Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information. In the opinion of the Company, the accompanying unaudited interim condensed consolidated financial statements reflect all adjustments, consisting of only normal recurring adjustments, considered necessary for a fair statement of such interim results. All intercompany balances and transactions have been eliminated. The equity attributable to noncontrolling interests in subsidiaries is shown separately in the accompanying condensed consolidated balance sheets. Certain prior period amounts have been reclassified to conform with current period presentation. The results for the unaudited interim condensed consolidated statements of operations are not necessarily indicative of results to be expected for the year ending December 31, 2026 or for any future interim period. The unaudited interim condensed consolidated financial statements do not include all the information and notes required by U.S. GAAP for complete presentation of annual financial statements. The accompanying unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025.
Use of Estimates in the Financial Statements	Use of Estimates in the Financial Statements The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates are used for (but are not limited to) such items as the fair values of assets acquired and liabilities assumed in business combinations and asset acquisitions, fair value of contingent consideration issued in a business combination, the establishment of useful lives for property, plant and equipment and intangible assets, the fair value of equity securities or warrants to purchase the Company’s Common Stock issued individually or as a component of a debt or equity offering, the fair value of changes to the conversion terms of embedded conversion features, the fair value and requisite service periods of stock-based compensation, the fair value of assets received in nonmonetary transactions, the fair value of nonmonetary consideration, the establishment of right-of-use assets and lease liabilities that arise from leasing arrangements, the timing of commencement of capitalization for plant and equipment, impairment of indefinite-lived intangible assets, impairment of long-lived assets, recoverability of deferred tax assets, amortization of deferred issuance costs and debt discount, the fair value of leased assets for the purpose of lease classification, and the recording of various accruals. These estimates are made after considering past and current events and assumptions about future events. Actual results could differ from those estimates.
Revenue Recognition	Revenue Recognition Mining Pool The Company has entered into an arrangement with a cryptocurrency mining pool (the Foundry USA Pool) to perform hash computations (i.e. hashrate) for the mining pool in exchange for consideration. Providing hash computation services to a mining pool is an output of the Company’s ordinary activities. The provision of such hash computation services is the sole performance obligation. The mining pool arrangement is terminable at any time without substantial penalty by Foundry USA Pool and may be terminated without substantial penalty by the Company upon providing one Contract Day’s, as defined, prior written notice. The Company’s enforceable right to compensation only begins when and continues while the Company provides hash computation services to its customer, the mining pool operator. Accordingly, the contract term with Foundry USA Pool is deemed to be less than 24 hours and to continuously renew throughout the day. Additionally, the Company concluded that the mining pool operator’s (i.e., the customer’s) renewal right is not a material right because the renewal rights do not include any discounts; that is, the terms, conditions, and compensation amounts are at the then-current market rates. There is no significant financing component in these transactions. The mining pool applies the Full Pay Per Share (“FPPS”) payout model. Under the FPPS model, in exchange for providing hash computation services to the pool, the Company is entitled to pay-per-share base amount and transaction fee reward compensation, calculated on a daily basis, at an amount that approximates the total bitcoin that could have been mined and transaction fees that could have been awarded using the Company’s hash computation services, based upon the then current blockchain difficulty. Under this model, the Company is entitled to compensation, payable in bitcoin, regardless of whether the pool operator successfully records a block to the bitcoin blockchain. The transaction consideration the Company receives, if any, is noncash consideration and is all variable. Because digital assets are considered noncash consideration, fair value of the digital asset award received would generally be determined using the quoted price of the related digital asset in the Company’s principal market at the time of contract inception. The Company has adopted an accounting policy to aggregate individual contracts with individual terms less than 24 hours within each intraday period and apply a consistent valuation point, the start of day Coordinated Universal Time (00:00:00 UTC), to value the related noncash consideration. Revenue is recognized when it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur, which is the same day that control of the contracted service transfers to the mining pool and is the same day as the contract inception. After every 24-hour contract term, the mining pool transfers the digital asset consideration to the Company’s designated digital assets wallets. Consideration payable to the customer in the form of a pool operator fee, which is incurred only to the extent that the Company has generated FPPS consideration, is deducted from the bitcoin the Company receives and is recorded as contra-revenue, as it does not represent a payment for a distinct good or service.
HPC Leasing	HPC Leasing In December 2024 and August 2025, the Company entered into long-term datacenter lease agreements (the “Core42 HPC Leases” and the “Fluidstack HPC Leases”, respectively, and collectively, the “HPC Leases”) with customers for specified datacenter infrastructure at the Lake Mariner Data Campus to support the customers’ HPC operations. In accordance with ASC 842, Leases, the Company determined at contract inception that these agreements contained a lease, comprising lease components related to the right to use datacenter space and nonlease components for power delivery, physical security, and maintenance services. As of June 30, 2026, all of the Core42 HPC Leases have commenced and one of the Fluidstack HPC Leases has partially commenced and the remaining Fluidstack HPC Leases are expected to commence in the second half of 2026 as well as in early 2027. In July 2026, TeraWulf had energized 102 MW of critical IT HPC capacity at the Lake Mariner Data Campus. The Company has elected the practical expedient available under ASC 842 to combine the nonlease revenue components that have the same pattern of transfer as the related operating lease components into a single combined component. The single combined component is accounted for under ASC 842 as an operating lease if the lease components are the predominant components and is accounted for under ASC 606 if the nonlease components are the predominant components. The lease components are the predominant components in the Company’s HPC Leases and the single combined component in these arrangements are accounted for under the operating lease guidance of ASC 842. Recognition of HPC lease revenue begins when the Company determines the asset has been made available for the customer’s use. The Company has concluded that it is probable that substantially all of the payments will be collected over the term of the arrangements and recognizes the total combined fixed payments under the agreements on a straight-line basis over the noncancellable term. The Company recognizes the difference between straight-line revenue recognized during the period and the lease payments due pursuant to the underlying arrangement as deferred rent liability or accrued rent receivable in the condensed consolidated balance sheets. Certain arrangements include options to extend the term. These extension options are not reasonably certain to be exercised and are excluded from the lease term and calculation of lease payments at lease commencement. Payments for physical security and other routine maintenance services are included in the fixed lease payments. The lease agreements provide for variable payments for power delivery. Power delivery services represent a stand-ready obligation to make power available to the customer over the coterminous lease term and have the same pattern of transfer as the related operating lease components. Customers are charged monthly for actual power costs incurred at current utility rates. These payments from customers for power delivery are recognized as variable lease payments in accordance with the practical expedient elected. Variable lease payments are presented on a gross basis and are included in HPC lease revenue in the condensed consolidated statements of operations. The lease agreements also provide for variable payments for certain fit-out services as requested by the customer and the Company recognizes revenues as performance obligations are satisfied, unless agreed with the customer to include the costs in the base rent. In the course of providing its services, the Company routinely subcontracts for services and incurs other direct costs on behalf of its customers. These costs are passed through to the customers, generally with a mark-up, and, in accordance with GAAP, are included in the Company’s HPC lease revenue .
Cost of Revenue	Cost of Revenue Cost of revenue for mining pool revenue is comprised primarily of direct costs of electricity, but excludes depreciation which is separately presented. Cost of revenue for HPC lease revenue is comprised primarily of direct costs of electricity and also includes costs incurred by the Company in connection with its fit-out services under the HPC Leases.
Power Curtailment Credits	Power Curtailment Credits Proceeds from participation in demand response programs are recorded as a reduction in cost of revenue in the condensed consolidated statements of operations for the period in which the corresponding demand response program occurs.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted Cash Highly liquid instruments with an original maturity of three months or less are classified as cash equivalents. As of June 30, 2026 and December 31, 2025, the Company had cash and cash equivalents of $2,619.2 million and $3,266.4 million, respectively. The Company considers cash and marketable securities to be restricted when withdrawal or general use is legally restricted. The Company reports restricted cash in the condensed consolidated balance sheets and determines current or noncurrent classification based on the expected duration of the restriction.
Digital Assets	Digital Assets Digital assets consists of bitcoin earned as noncash consideration for providing hash computation services to a mining pool, in accordance with the Company’s revenue recognition policy. Digital assets is classified as a current asset in the condensed consolidated balance sheets as it is highly liquid and the Company expects to sell it within the next twelve months to support operations. The Company measures digital assets at fair value each reporting period in accordance with ASC 820, Fair Value Measurement (“ASC 820”). Fair value is determined using Level 1 inputs based on quoted prices from the active trading platform on which the Company regularly transacts, which is considered its principal market for bitcoin. Because bitcoin is continuously traded, the Company uses the midnight UTC price to align with its revenue recognition policy. Gains and losses from remeasurement are included within “loss (gain) on fair value of digital assets, net” in the condensed consolidated statements of operations. For bitcoin sales, gains and losses are calculated as the difference between cash proceeds and the cost basis, using a first-in, first-out (FIFO) method. These gains and losses are also included within “loss (gain) on fair value of digital assets, net” in the condensed consolidated statements of operations. The Company recorded loss (gain) on fair value of digital assets, net of $0.8 million and $1.5 million during the three and six months ended June 30, 2026, respectively, and $(0.9) million and $(17,000) during the three and six months ended June 30, 2025, respectively. Bitcoin earned through mining activities is recorded as an adjustment in the condensed consolidated statements of cash flows, reconciling net loss to cash flows from operating activities. Bitcoin received as distributions-in-kind from equity investees is disclosed in supplemental noncash investing activities. Prior to July 2024, proceeds from sales of digital assets were included within cash flows from operating activities in the condensed consolidated statements of cash flows as bitcoin was converted nearly immediately into cash during that period. Starting in July 2024, the Company no longer converts bitcoin into cash immediately and accordingly, proceeds from sales of digital assets are included within cash flows from investing activities in the condensed consolidated statements of cash flows.
Concentrations	Concentrations During 2026 and 2025, the Company contracted with one supplier for the provision of bitcoin miners and one mining pool operator. For the three and six months ended June 30, 2026, the Company’s HPC lease revenue was generated from two customers. For the three and six months ended June 30, 2025, the Company derived 100% of its revenues from bitcoin mining. The Company does not believe that these counterparties represent a significant performance risk. If the market value of bitcoin declines significantly, the condensed consolidated financial condition and results of operations of the Company may be adversely affected.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are recorded at cost, net of accumulated depreciation. The Company capitalizes the cost of additions and major improvements and modifications to property, plant, and equipment. The cost of repairs and normal maintenance of property, plant, and equipment is expensed as incurred. Major improvements and modifications of property, plant, and equipment are those expenditures that either extend the useful life or improve the operating efficiency of the asset. Depreciation is computed using the straight-line method over the estimated useful lives of the assets (generally 2 to 5 years for computer equipment and 4 years for miners, 2 to 25 years for electrical equipment, 5 to 20 years for building and improvements, 2 to 10 years for office furniture and fixtures, and 2 to 7 years for vehicles). Leasehold improvements are depreciated over the shorter of their estimated useful lives (25 years) or the lease term. Changes in depreciation and amortization, generally accelerated depreciation and variable amortization, are determined and recorded when estimates of the remaining useful lives or residual values of long-term assets change. Interest related to construction of assets is capitalized when the financial statement effect of capitalization is material, construction of the asset has begun, and interest is being incurred. Interest capitalization ends at the earlier of the asset being substantially complete and ready for its intended use or when interest costs are no longer being incurred.
Asset Retirement Obligation	Asset Retirement Obligation The Company recognizes the fair value of a liability for an asset retirement obligation in the period in which it was incurred if a reasonable estimate of fair value can be made. When the liability is recorded, the Company capitalizes a cost by increasing the carrying amount of the related long-lived asset. Over time, the liability is accreted to its present value each period, and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, the Company will settle the obligation for its recorded amount or incur a gain or loss. If any of the assumptions the Company used to value the retirement obligation materially changed, it will review and reassess its estimates to determine if an adjustment to the asset retirement obligation is required. The Company’s asset retirement obligations relate primarily to asbestos remediation and spent pot liner removal at the Justified Data Campus.
Impairment of Long-lived Assets	Impairment of Long-lived Assets The Company reviews its long-lived assets, including property, plant and equipment, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset, or asset group, may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to undiscounted future cash flows expected to be generated by the asset. Any impairment loss recorded is measured as the amount by which the carrying value of the assets exceeds the fair value of the assets.
Business Combinations	Business Combinations The Company includes the results of operations of the businesses it acquires as of the acquisition date. The Company allocates the purchase price of the acquisitions to the assets acquired and liabilities assumed based on their estimated fair values. The excess of the purchase price over the fair values of identifiable assets and liabilities is recorded as goodwill. Contingent consideration is included within the purchase price and is recognized at its fair value on the acquisition date. A liability resulting from contingent consideration is remeasured to fair value as of each reporting date until the contingency is resolved, and subsequent changes in fair value are recognized in earnings. While the Company uses its best estimates and assumptions to accurately apply preliminary values to assets acquired and liabilities assumed at the acquisition date as well as contingent consideration, where applicable, these estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of the assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded in the condensed consolidated statements of operations. Accounting for business combinations requires management to make significant estimates and assumptions, especially at the acquisition date, including estimates for assets acquired, liabilities assumed, and contingent consideration, where applicable. Although the Company believes the assumptions and estimates it has made have been reasonable and appropriate, they are based in part on historical experience and information obtained from management of the acquired companies and are inherently uncertain. Critical estimates include valuation of the contingent consideration transferred, and assets acquired and liabilities assumed. Unanticipated events and circumstances may occur that may affect the accuracy or validity of such assumptions, estimates, or actual results. Acquisition-related expenses are recognized separately from the business combination and are expensed as incurred.
Asset Acquisition	Asset Acquisition The Company evaluates acquisitions of assets and other similar transactions to assess whether or not the transaction should be accounted for as a business combination or asset acquisition by first applying a screen to determine if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. If the screen is met, the transaction is accounted for as an asset acquisition. If the screen is not met, further determination is required as to whether the Company has acquired inputs and processes that have the ability to create outputs, which would meet the requirements of a business. If determined to be an asset acquisition, the Company recognizes the assets acquired and liabilities assumed based on the cost of acquiring the assets, which generally includes the transaction costs of the asset acquisition and no gain or loss is recognized as of the date of acquisition unless the fair value of noncash assets given as consideration differs from the assets’ carrying amounts on the Company’s books. If the consideration given includes noncash consideration in the form of noncash assets, liabilities assumed or equity interests issued, the Company measures the cost of acquiring the assets based on either the fair value of the consideration given or the fair value of the assets (or net assets) acquired, whichever is more clearly evident and, thus, more reliably measurable. Goodwill is not recognized in an asset acquisition and any excess consideration transferred over the fair value of the net assets acquired is allocated to the identifiable assets based on relative fair values. Any contingent consideration in an asset acquisition is recognized only when amounts are both probable and estimable, at which point the consideration is allocated to the assets acquired on a relative fair value basis.
Goodwill	Goodwill The Company evaluates goodwill for impairment annually or more frequently when an event occurs or circumstances change that indicate the carrying value may not be recoverable. The Company may elect to utilize a qualitative assessment to evaluate whether it is more likely than not that the fair value of a reporting unit is less than its carrying value and if so, it performs a quantitative test. If a quantitative test is required, the Company estimates the fair value of the reporting unit using discounted cash flows. The Company’s analyses require significant assumptions and judgments, including assumptions about future economic conditions, revenue growth, and operating margins, among other factors. Events or changes in circumstances considered in the qualitative analysis, many of which are subjective in nature, include: a significant negative trend in the Company’s industry or overall economic trends, a significant change in how the Company uses the acquired assets, a significant change in business strategy, a significant decrease in the market value of the asset, and a significant change in regulations or in the industry that could affect the value of the asset. The Company compares the carrying value of each reporting unit to its estimated fair value and if the fair value is determined to be less than the carrying value, the Company would recognize an impairment loss for the difference.
Derivatives	Derivatives The Company does not apply hedge accounting to its derivatives. Rather changes in the fair values of derivatives for a particular period are recognized in the condensed consolidated statements of operations. The Company evaluates its contracts to determine if they meet the definition of a derivative instrument. If a contract meets the definition, the Company evaluates whether it qualifies for the normal purchases and normal sales exemption and may elect the exemption if the criteria is met.
Loss per Share	Loss per Share The Company computes earnings (loss) per share using the two-class method required for participating securities. The two-class method requires income available to common stockholders for the period to be allocated between Common Stock and participating securities based upon their respective rights to receive dividends as if all income for the period had been distributed. Basic loss per share of Common Stock is calculated by dividing the Company’s net loss by the weighted average number of shares of Common Stock outstanding during the period. Diluted loss per share reflects the potential dilution that could occur if other instruments were converted into Common Stock, using the treasury stock method or if-converted method, as applicable. However, for periods in which the Company reports a net loss, all potentially dilutive instruments are excluded from the calculation of diluted loss per share, as their inclusion would be anti-dilutive. As of June 30, 2026, the Company’s potentially dilutive instruments and participating securities included Common Stock warrants, convertible notes, and restricted stock units (“RSUs”) issued for services.
Segment Reporting	Segment Reporting The Company has two operating segments: “Digital Asset Mining,” consisting of providing hash computation services to a mining pool operator and “HPC Leasing,” consisting of providing high-density colocation services to third parties for HPC operations and all operations are domiciled in the United States of America. The reportable segments are identified based on the types of services performed. The Company’s HPC Leasing operations met the criteria to be considered a new segment during the third quarter of 2025. The Digital Asset Mining segment generates revenue from operating owned digital infrastructure and computer equipment as part of a pool of users that process transactions conducted on one or more blockchain networks. In exchange for these services, the Company receives digital assets. The HPC Leasing segment generates revenue through lease agreements providing the right to use datacenter space and providing power delivery, physical security, and maintenance services. The Company’s operations are evaluated regularly by the chief operating decision maker, or decision–making group (“CODM”), which is composed of the Chief Executive Officer, Chief Technology Officer and Chief Strategy Officer, to assess performance and allocate resources. The CODM uses segment profit (loss) to evaluate performance and allocate resources. Segment profit (loss) is used to evaluate actual results against expectations, which are based on comparable prior results, and current budget. Segment profit (loss) is also used in deciding how profits and cash flows will be reinvested or otherwise deployed. No asset information for reportable segments is provided to the CODM as the CODM does not evaluate performance or allocate resources based on segment asset or liability information; accordingly, the Company has not presented a measure of assets by segment. The segments’ accounting policies are the same as those described in the summary of significant accounting policies. The Company excludes certain operating expenses and other expenses from the allocations to operating segments.

Basis of Presentation and Principles of Consolidation

The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information. In the opinion of the Company, the accompanying unaudited interim condensed consolidated financial statements reflect all adjustments, consisting of only normal recurring adjustments, considered necessary for a fair statement of such interim results. All intercompany balances and transactions have been eliminated. The equity attributable to noncontrolling interests in subsidiaries is shown separately in the accompanying condensed consolidated balance sheets. Certain prior period amounts have been reclassified to conform with current period presentation.

The results for the unaudited interim condensed consolidated statements of operations are not necessarily indicative of results to be expected for the year ending December 31, 2026 or for any future interim period. The unaudited interim condensed consolidated financial statements do not include all the information and notes required by U.S. GAAP for complete presentation of annual financial statements. The accompanying unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

Use of Estimates in the Financial Statements

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates are used for (but are not limited to) such items as the fair values of assets acquired and liabilities assumed in business combinations and asset acquisitions, fair value of contingent consideration issued in a business combination, the establishment of useful lives for property, plant and equipment and intangible assets, the fair value of equity securities or warrants to purchase the Company’s Common Stock issued individually or as a component of a debt or equity offering, the fair value of changes to the conversion terms of embedded conversion features, the fair value and requisite service periods of stock-based compensation, the fair value of assets received in nonmonetary transactions, the fair value of nonmonetary consideration, the establishment of right-of-use assets and lease liabilities that arise from leasing arrangements, the timing of commencement of capitalization for plant and equipment, impairment of indefinite-lived intangible assets, impairment of long-lived assets, recoverability of deferred tax assets, amortization of deferred issuance costs and debt discount, the fair value of leased assets for the purpose of lease classification, and the recording of various accruals. These estimates are made after considering past and current events and assumptions about future events. Actual results could differ from those estimates.

Revenue Recognition

Mining Pool

The Company has entered into an arrangement with a cryptocurrency mining pool (the Foundry USA Pool) to perform hash computations (i.e. hashrate) for the mining pool in exchange for consideration. Providing hash computation services to a mining pool is an output of the Company’s ordinary activities. The provision of such hash computation services is the sole performance obligation. The mining pool arrangement is terminable at any time without substantial penalty by Foundry USA Pool and may be terminated without substantial penalty by the Company upon providing one Contract Day’s, as defined, prior written notice. The Company’s enforceable right to compensation only begins when and continues while the Company provides hash computation services to its customer, the mining pool operator. Accordingly, the contract term with Foundry USA Pool is deemed to be less than 24 hours and to continuously renew throughout the day. Additionally, the Company concluded that the mining pool operator’s (i.e., the customer’s) renewal right is not a material right because the renewal rights do not include any discounts; that is, the terms, conditions, and compensation amounts are at the then-current market rates.

There is no significant financing component in these transactions.

The mining pool applies the Full Pay Per Share (“FPPS”) payout model. Under the FPPS model, in exchange for providing hash computation services to the pool, the Company is entitled to pay-per-share base amount and transaction fee reward compensation, calculated on a daily basis, at an amount that approximates the total bitcoin that could have been mined and transaction fees that could have been awarded using the Company’s hash computation services, based upon the then current blockchain difficulty. Under this model, the Company is entitled to compensation, payable in bitcoin, regardless of whether the pool operator successfully records a block to the bitcoin blockchain.

The transaction consideration the Company receives, if any, is noncash consideration and is all variable. Because digital assets are considered noncash consideration, fair value of the digital asset award received would generally be determined using the quoted price of the related digital asset in the Company’s principal market at the time of contract inception. The Company has adopted an accounting policy to aggregate individual contracts with individual terms less than 24 hours within each intraday period and apply a consistent valuation point, the start of day Coordinated Universal Time (00:00:00 UTC), to value the related noncash consideration. Revenue is recognized when it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur, which is the same day that control of the contracted service transfers to the mining pool and is the same day as the contract inception. After every 24-hour contract term, the mining pool transfers the digital asset consideration to the Company’s designated digital assets wallets.

Consideration payable to the customer in the form of a pool operator fee, which is incurred only to the extent that the Company has generated FPPS consideration, is deducted from the bitcoin the Company receives and is recorded as contra-revenue, as it does not represent a payment for a distinct good or service.

HPC Leasing

In December 2024 and August 2025, the Company entered into long-term datacenter lease agreements (the “Core42 HPC Leases” and the “Fluidstack HPC Leases”, respectively, and collectively, the “HPC Leases”) with customers for specified datacenter infrastructure at the Lake Mariner Data Campus to support the customers’ HPC operations. In accordance with ASC 842, Leases, the Company determined at contract inception that these agreements contained a lease, comprising lease components related to the right to use datacenter space and nonlease components for power delivery, physical security, and maintenance services. As of June 30, 2026, all of the Core42 HPC Leases have commenced and one of the Fluidstack HPC Leases has partially commenced and the remaining Fluidstack HPC Leases are expected to commence in the second half of 2026 as well as in early 2027. In July 2026, TeraWulf had energized 102 MW of critical IT HPC capacity at the Lake Mariner Data Campus.

The Company has elected the practical expedient available under ASC 842 to combine the nonlease revenue components that have the same pattern of transfer as the related operating lease components into a single combined component. The single combined component is accounted for under ASC 842 as an operating lease if the lease components are the predominant components and is accounted for under ASC 606 if the nonlease components are the predominant components. The lease components are the predominant components in the Company’s HPC Leases and the single combined component in these arrangements are accounted for under the operating lease guidance of ASC 842. Recognition of HPC lease revenue begins when the Company determines the asset has been made available for the customer’s use.

The Company has concluded that it is probable that substantially all of the payments will be collected over the term of the arrangements and recognizes the total combined fixed payments under the agreements on a straight-line basis over the noncancellable term. The Company recognizes the difference between straight-line revenue recognized during the period and the lease payments due pursuant to the underlying arrangement as deferred rent liability or accrued rent receivable in the condensed consolidated balance sheets. Certain arrangements include options to extend the term. These extension options are not reasonably certain to be exercised and are excluded from the lease term and calculation of lease payments at lease commencement.

Payments for physical security and other routine maintenance services are included in the fixed lease payments. The lease agreements provide for variable payments for power delivery. Power delivery services represent a stand-ready obligation to make power available to the customer over the coterminous lease term and have the same pattern of transfer as the related operating lease components. Customers are charged monthly for actual power costs incurred at current utility rates. These payments from customers for power delivery are recognized as variable lease payments in accordance with the practical expedient elected. Variable lease payments are presented on a gross basis and are included in HPC lease revenue in the condensed consolidated statements of operations.

The lease agreements also provide for variable payments for certain fit-out services as requested by the customer and the Company recognizes revenues as performance obligations are satisfied, unless agreed with the customer to include the costs in the base rent. In the course of providing its services, the Company routinely subcontracts for services and incurs other direct costs on behalf of its customers. These costs are passed through to the customers, generally with a mark-up, and, in accordance with GAAP, are included in the Company’s HPC lease revenue .

Cost of Revenue

Cost of revenue for mining pool revenue is comprised primarily of direct costs of electricity, but excludes depreciation which is separately presented. Cost of revenue for HPC lease revenue is comprised primarily of direct costs of electricity and also includes costs incurred by the Company in connection with its fit-out services under the HPC Leases.

Power Curtailment Credits

Proceeds from participation in demand response programs are recorded as a reduction in cost of revenue in the condensed consolidated statements of operations for the period in which the corresponding demand response program occurs.

Cash, Cash Equivalents and Restricted Cash

Highly liquid instruments with an original maturity of three months or less are classified as cash equivalents. As of June 30, 2026 and December 31, 2025, the Company had cash and cash equivalents of $2,619.2 million and $3,266.4 million, respectively.

The Company considers cash and marketable securities to be restricted when withdrawal or general use is legally restricted. The Company reports restricted cash in the condensed consolidated balance sheets and determines current or noncurrent classification based on the expected duration of the restriction.

Digital Assets

Digital assets consists of bitcoin earned as noncash consideration for providing hash computation services to a mining pool, in accordance with the Company’s revenue recognition policy. Digital assets is classified as a current asset in the condensed consolidated balance sheets as it is highly liquid and the Company expects to sell it within the next twelve months to support operations.

The Company measures digital assets at fair value each reporting period in accordance with ASC 820, Fair Value Measurement (“ASC 820”). Fair value is determined using Level 1 inputs based on quoted prices from the active trading platform on which the Company regularly transacts, which is considered its principal market for bitcoin. Because bitcoin is continuously traded, the Company uses the midnight UTC price to align with its revenue recognition policy. Gains and losses from remeasurement are included within “loss (gain) on fair value of digital assets, net” in the condensed consolidated statements of operations.

For bitcoin sales, gains and losses are calculated as the difference between cash proceeds and the cost basis, using a first-in, first-out (FIFO) method. These gains and losses are also included within “loss (gain) on fair value of digital assets, net” in the condensed consolidated statements of operations. The Company recorded loss (gain) on fair value of digital assets, net of $0.8 million and $1.5 million during the three and six months ended June 30, 2026, respectively, and $(0.9) million and $(17,000) during the three and six months ended June 30, 2025, respectively.

Bitcoin earned through mining activities is recorded as an adjustment in the condensed consolidated statements of cash flows, reconciling net loss to cash flows from operating activities. Bitcoin received as distributions-in-kind from equity investees is disclosed in supplemental noncash investing activities.

Prior to July 2024, proceeds from sales of digital assets were included within cash flows from operating activities in the condensed consolidated statements of cash flows as bitcoin was converted nearly immediately into cash during that period. Starting in July 2024, the Company no longer converts bitcoin into cash immediately and accordingly, proceeds from sales of digital assets are included within cash flows from investing activities in the condensed consolidated statements of cash flows.

Concentrations

During 2026 and 2025, the Company contracted with one supplier for the provision of bitcoin miners and one mining pool operator. For the three and six months ended June 30, 2026, the Company’s HPC lease revenue was generated from two customers. For the three and six months ended June 30, 2025, the Company derived 100% of its revenues from bitcoin mining. The Company does not believe that these counterparties represent a significant performance risk. If the market value of bitcoin declines significantly, the condensed consolidated financial condition and results of operations of the Company may be adversely affected.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost, net of accumulated depreciation. The Company capitalizes the cost of additions and major improvements and modifications to property, plant, and equipment. The cost of repairs and normal maintenance of property, plant, and equipment is expensed as incurred. Major improvements and modifications of property, plant, and equipment are those expenditures that either extend the useful life or improve the operating efficiency of the asset.

Depreciation is computed using the straight-line method over the estimated useful lives of the assets (generally 2 to 5 years for computer equipment and 4 years for miners, 2 to 25 years for electrical equipment, 5 to 20 years for building and improvements, 2 to 10 years for office furniture and fixtures, and 2 to 7 years for vehicles). Leasehold improvements are depreciated over the shorter of their estimated useful lives (25 years) or the lease term. Changes in depreciation and amortization, generally accelerated depreciation and variable amortization, are determined and recorded when estimates of the remaining useful lives or residual values of long-term assets change.

Interest related to construction of assets is capitalized when the financial statement effect of capitalization is material, construction of the asset has begun, and interest is being incurred. Interest capitalization ends at the earlier of the asset being substantially complete and ready for its intended use or when interest costs are no longer being incurred.

Asset Retirement Obligation

The Company recognizes the fair value of a liability for an asset retirement obligation in the period in which it was incurred if a reasonable estimate of fair value can be made. When the liability is recorded, the Company capitalizes a cost by increasing the carrying amount of the related long-lived asset. Over time, the liability is accreted to its present value each period, and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, the Company will settle the obligation for its recorded amount or incur a gain or loss. If any of the assumptions the Company used to value the retirement obligation materially changed, it will review and reassess its estimates to determine if an adjustment to the asset retirement obligation is required. The Company’s asset retirement obligations relate primarily to asbestos remediation and spent pot liner removal at the Justified Data Campus.

Impairment of Long-lived Assets

The Company reviews its long-lived assets, including property, plant and equipment, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset, or asset group, may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to undiscounted future cash flows expected to be generated by the asset. Any impairment loss recorded is measured as the amount by which the carrying value of the assets exceeds the fair value of the assets.

Business Combinations

The Company includes the results of operations of the businesses it acquires as of the acquisition date. The Company allocates the purchase price of the acquisitions to the assets acquired and liabilities assumed based on their estimated fair values. The excess of the purchase price over the fair values of identifiable assets and liabilities is recorded as goodwill. Contingent consideration is included within the purchase price and is recognized at its fair value on the acquisition date. A liability resulting from contingent consideration is remeasured to fair value as of each reporting date until the contingency is resolved, and subsequent changes in fair value are recognized in earnings.

While the Company uses its best estimates and assumptions to accurately apply preliminary values to assets acquired and liabilities assumed at the acquisition date as well as contingent consideration, where applicable, these estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of the assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded in the condensed consolidated statements of operations. Accounting for business combinations requires management to make significant estimates and assumptions, especially at the acquisition date, including estimates for assets acquired, liabilities assumed, and contingent consideration, where applicable. Although the Company believes the assumptions and estimates it has made have been reasonable and appropriate, they are based in part on historical experience and information obtained from management of the acquired companies and are inherently uncertain. Critical estimates include valuation of the contingent consideration transferred, and assets acquired and liabilities assumed. Unanticipated events and circumstances may occur that may affect the accuracy or validity of such assumptions, estimates, or actual results. Acquisition-related expenses are recognized separately from the business combination and are expensed as incurred.

Asset Acquisition

The Company evaluates acquisitions of assets and other similar transactions to assess whether or not the transaction should be accounted for as a business combination or asset acquisition by first applying a screen to determine if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. If the screen is met, the transaction is accounted for as an asset acquisition. If the screen is not met, further determination is required as to whether the Company has acquired inputs and processes that have the ability to create outputs, which would meet the requirements of a business.

If determined to be an asset acquisition, the Company recognizes the assets acquired and liabilities assumed based on the cost of acquiring the assets, which generally includes the transaction costs of the asset acquisition and no gain or loss is recognized as of the date of acquisition unless the fair value of noncash assets given as consideration differs from the assets’ carrying amounts on the Company’s books. If the consideration given includes noncash consideration in the form of noncash assets, liabilities assumed or equity interests issued, the Company measures the cost of acquiring the assets based on either the fair value of the consideration given or the fair value of the assets (or net assets) acquired, whichever is more clearly evident and, thus, more reliably measurable. Goodwill is not recognized in an asset acquisition and any excess consideration transferred over the fair value of the net assets acquired is allocated to the identifiable assets based on relative fair values. Any contingent consideration in an asset acquisition is recognized only when amounts are both probable and estimable, at which point the consideration is allocated to the assets acquired on a relative fair value basis.

Goodwill

The Company evaluates goodwill for impairment annually or more frequently when an event occurs or circumstances change that indicate the carrying value may not be recoverable. The Company may elect to utilize a qualitative assessment to evaluate whether it is more likely than not that the fair value of a reporting unit is less than its carrying value and if so, it performs a quantitative test.

If a quantitative test is required, the Company estimates the fair value of the reporting unit using discounted cash flows. The Company’s analyses require significant assumptions and judgments, including assumptions about future economic conditions, revenue growth, and operating margins, among other factors. Events or changes in circumstances considered in the qualitative analysis, many of which are subjective in nature, include: a significant negative trend in the Company’s industry or overall economic trends, a significant change in how the Company uses the acquired assets, a significant change in business strategy, a significant decrease in the market value of the asset, and a significant change in regulations or in the industry that could affect the value of the asset. The Company compares the carrying value of each reporting unit to its estimated fair value and if the fair value is determined to be less than the carrying value, the Company would recognize an impairment loss for the difference.

Derivatives

The Company does not apply hedge accounting to its derivatives. Rather changes in the fair values of derivatives for a particular period are recognized in the condensed consolidated statements of operations. The Company evaluates its contracts to determine if they meet the definition of a derivative instrument. If a contract meets the definition, the Company evaluates whether it qualifies for the normal purchases and normal sales exemption and may elect the exemption if the criteria is met.

Loss per Share

The Company computes earnings (loss) per share using the two-class method required for participating securities. The two-class method requires income available to common stockholders for the period to be allocated between Common Stock and participating securities based upon their respective rights to receive dividends as if all income for the period had been distributed.

Basic loss per share of Common Stock is calculated by dividing the Company’s net loss by the weighted average number of shares of Common Stock outstanding during the period. Diluted loss per share reflects the potential dilution that could occur if other instruments were converted into Common Stock, using the treasury stock method or if-converted method, as applicable. However, for periods in which the Company reports a net loss, all potentially dilutive instruments are excluded from the calculation of diluted loss per share, as their inclusion would be anti-dilutive.

As of June 30, 2026, the Company’s potentially dilutive instruments and participating securities included Common Stock warrants, convertible notes, and restricted stock units (“RSUs”) issued for services.

Segment Reporting

The Company has two operating segments: “Digital Asset Mining,” consisting of providing hash computation services to a mining pool operator and “HPC Leasing,” consisting of providing high-density colocation services to third parties for HPC operations and all operations are domiciled in the United States of America. The reportable segments are identified based on the types of services performed. The Company’s HPC Leasing operations met the criteria to be considered a new segment during the third quarter of 2025. The Digital Asset Mining segment generates revenue from operating owned digital infrastructure and computer equipment as part of a pool of users that process transactions conducted on one or more blockchain networks. In exchange for these services, the Company receives digital assets. The HPC Leasing segment generates revenue through lease agreements providing the right to use datacenter space and providing power delivery, physical security, and maintenance services.

The Company’s operations are evaluated regularly by the chief operating decision maker, or decision–making group (“CODM”), which is composed of the Chief Executive Officer, Chief Technology Officer and Chief Strategy Officer, to assess performance and allocate resources. The CODM uses segment profit (loss) to evaluate performance and allocate resources. Segment profit (loss) is used to evaluate actual results against expectations, which are based on comparable prior results, and current budget. Segment profit (loss) is also used in deciding how profits and cash flows will be reinvested or otherwise deployed. No asset information for reportable segments is provided to the CODM as the CODM does not evaluate performance or allocate resources based on segment asset or liability information; accordingly, the Company has not presented a measure of assets by segment. The segments’ accounting policies are the same as those described in the summary of significant accounting policies. The Company excludes certain operating expenses and other expenses from the allocations to operating segments.
