Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying Consolidated Financial Statements of Strategy Inc (“Strategy,” or the “Company”) are unaudited. The Consolidated Financial Statements and Notes to Consolidated Financial Statements are presented as required by the rules and regulations of the United States Securities and Exchange Commission (“SEC”) for interim reporting and do not contain certain information included in the Company’s annual financial statements and notes. These financial statements should be read in conjunction with the Company’s audited financial statements and the notes thereto filed with the SEC in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025. There have been no significant changes in the Company’s accounting policies since December 31, 2025. Certain prior period amounts have been reclassified and aggregated to conform to the current period presentation. These changes did not have a material impact on the Company’s Consolidated Financial Statements and no underlying accounting policies or measurement bases have changed. In the opinion of management, all adjustments necessary for a fair statement of financial position and results of operations have been included. All such adjustments are of a normal recurring nature, unless otherwise disclosed. Interim results are not necessarily indicative of results for a full year.
Reclassification	Certain prior period amounts have been reclassified and aggregated to conform to the current period presentation. These changes did not have a material impact on the Company’s Consolidated Financial Statements and no underlying accounting policies or measurement bases have changed.
Consolidation	The accompanying Consolidated Financial Statements include the accounts of the Company and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.
Digital Assets	Digital Assets The Company initially records its bitcoin purchases at cost and any increases or decreases in fair value are recognized as incurred in the Company's Consolidated Statements of Operations, and the fair value of the Company’s bitcoin is reflected within the Company's Consolidated Balance Sheet each reporting period-end. The Company establishes a deferred tax liability when the fair value of bitcoin at the reporting date exceeds the average cost basis of the Company’s bitcoin holdings at that date. Subsequent increases or decreases in the fair value of bitcoin result in corresponding increases or decreases to the deferred tax liability. If the fair value of bitcoin declines below the Company’s cost basis, the deferred tax liability related to unrealized gains is reversed, and a deferred tax asset is recognized for the resulting unrealized loss. The Company evaluates the realizability of deferred tax assets each reporting period and records a valuation allowance against its U.S. federal and state deferred tax assets when it is more likely than not that some or all of the deferred tax assets will not be realized. In determining the gain or loss to be recognized upon the sale of bitcoin, the Company calculates the difference between the sales price and fair value of the specific bitcoin sold immediately prior to sale and records any gain or loss in the period in which the sale occurs. The Company accounts for its digital assets, which are comprised solely of bitcoin, as indefinite-lived intangible assets in accordance with ASC 350, Intangibles—Goodwill and Other and ASU 2023-08, Intangibles—Goodwill and Other—Crypto Assets. The Company’s digital assets are initially recorded at cost. Subsequent to the Company’s adoption of ASU 2023-08 on January 1, 2025, bitcoin assets are measured at fair value as of each reporting period. The Company determines the fair value of its bitcoin in accordance with ASC 820, Fair Value Measurement, based on quoted (unadjusted) prices on the Coinbase exchange, the active exchange that the Company has determined is its principal market for bitcoin (Level 1 inputs). Changes in fair value and gains or losses on sales are recognized as incurred in the Company's Consolidated Statements of Operations, within “Unrealized loss (gain) on digital assets”, within operating expenses in the Company’s Consolidated Statement of Operations.
Redeemable Preferred Stock	Redeemable Preferred Stock As of June 30, 2026, the following series of preferred stock of the Company were outstanding: •10.00% Series A Perpetual Strife Preferred Stock (“STRF Stock”); •Variable Rate Series A Perpetual Stretch Preferred Stock (“STRC Stock”); •10.00% Series A Perpetual Stream Preferred Stock ("STRE Stock"); •8.00% Series A Perpetual Strike Preferred Stock (“STRK Stock”); and •10.00% Series A Perpetual Stride Preferred Stock (“STRD Stock”). In these Notes to Consolidated Financial Statements, STRF Stock, STRC Stock, STRE Stock, STRK Stock and STRD Stock are collectively referred to as “Preferred Stock.” In accordance with Accounting Standards Codification (“ASC”) 480, Distinguishing Liabilities from Equity, each series of Preferred Stock outstanding as of June 30, 2026 is classified within mezzanine equity, as certain events that could cause shares of each such series of Preferred Stock to become redeemable are not solely within the control of the Company. In each case, the carrying values of the shares are initially recognized based on proceeds received, net of issuance costs, and are not accreted to their redemption value unless it becomes probable that the shares will become redeemable. Refer to Note 10, Redeemable Preferred Stock for further discussion.
Interest Income (Expense), Net	Interest Income (Expense), Net Interest income consists of interest earned on the Company’s cash and cash equivalents and short-term investments, which are invested in money market funds and other interest-bearing instruments. Interest income is recognized on an accrual basis as earned. Interest expense consists of contractual interest and the amortization of debt issuance costs on the Company’s Convertible Notes, recognized using the effective interest method over the expected term of the related instrument. Refer to Note 6, Long-term Debt, for further discussion of the Company’s indebtedness. Interest income and interest expense are presented on a net basis within “Interest income (expense), net” in the accompanying Consolidated Statements of Operations.
Recent Accounting Standards	Recent Accounting Standards The following Accounting Standards Updates (“ASU”) were issued by the FASB but have not yet been adopted: In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40), which requires further disaggregation of specific expense captions in the notes to consolidated financial statements. The guidance is effective for the Company’s 2027 annual and 2028 interim periods, with early adoption permitted. The Company is currently evaluating the impact of this standard on its disclosures and does not expect the adoption to have a material impact on its consolidated financial statements. In September 2025, the FASB issued ASU No. 2025-06, Intangibles: Goodwill and Other‒Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software (ASU 2025-06). Upon adoption, the Company will be required to account for internal-use software under the updated capitalization criteria. The standard is effective for the Company's interim and annual 2028 periods, with early adoption permitted. The standard can be applied either prospectively, retrospectively, or under a modified transition approach. The Company is currently evaluating the impact of this standard on its consolidated financial statements as well as its method of adoption.
