Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION	ORGANIZATION Nature of operations Cipher Mining Inc. (“Cipher” or the “Company”) is focused on the development and operation of industrial-scale data centers for bitcoin mining and high-performance compute (“HPC”) hosting. The Company operates two wholly-owned bitcoin mining data centers, a 207 MW site located in Odessa, Texas that draws fixed priced power from a power purchase agreement with its electricity provider (the “Odessa Facility”), and a 300 MW data center in Wink, Texas that draws power from the power grid (the “Black Pearl Facility”) and has equity investments in three partially-owned joint venture bitcoin mining data centers. The Company’s portfolio as of June 30, 2025 also includes three wholly-owned sites which have not commenced operations, and options to acquire three additional wholly-owned sites. Risks and uncertainties Liquidity and capital resources The Company has historically experienced net losses and negative cash flows from operations; however, proceeds from sales of bitcoin are categorized as cash flows from investing activities to the extent bitcoin is sold after seven days of receipt. As of June 30, 2025, the Company had approximate balances of cash and cash equivalents of $62.7 million, working capital of $167.2 million, total stockholders’ equity of $748.9 million and an accumulated deficit of $266.2 million. The Company uses a combination of proceeds from sales of bitcoin earned by or received from its bitcoin mining data centers, short-term and long-term financing arrangements, and strategic sales of shares through “at-the-market” offerings to support its operating expenses and capital expenditures. The Company monitors its balance sheet on an ongoing basis to determine the proper mix of bitcoin retention and bitcoin sales to support its cash requirements, ongoing operations, and capital expenditures. Bitcoin is classified as a current asset on the Company’s balance sheets due to its intent and ability to sell bitcoin to support operations when needed. Approximately $103.5 million of cash was used for operating activities during the six months ended June 30, 2025. During the six months ended June 30, 2025, the Company sold bitcoin for proceeds of approximately $121.4 million, paid approximately $162.4 million for deposits on equipment primarily related to new miner purchases, and paid approximately $55.9 million for property and equipment primarily related to the build-out of the Black Pearl Facility. The Company has a master loan agreement with Coinbase Credit, Inc., as Lender, and Coinbase, Inc., as Lending Service Provider (the “Coinbase Master Loan Agreement”). Pursuant to the master loan agreement, the Company has a secured line of credit up to $25.0 million (the “Coinbase Overnight Credit Facility”), and a term loan facility with Coinbase with a limit of $35.0 million and maximum period of one year (the “Term Loan Facility”). As described in more detail in Note 14. Debt, the borrowings are collateralized by bitcoin transferred to the Lending Service Provider’s platform. On May 22, 2025, the Company issued $172.5 million principal amount of convertible notes due in 2030 with an interest rate of 1.75% (the “2030 Convertible Notes”). The 2030 Convertible Notes are senior, unsecured obligations with interest due semiannually on May 15 and November 15 each year beginning on November 15, 2025. Refer to Note 14. Debt for more details. Management believes that the Company’s existing financial resources, combined with projected cash and bitcoin inflows from its data centers, its ability to sell bitcoin received or earned, and its intent and ability to sell common stock through at-the-market offerings will be sufficient to enable the Company to meet its operating and capital requirements for at least 12 months from the date these condensed consolidated financial statements are issued.
