Strategy disclosed $2.01 billion Bitcoin purchase funded by stock sales

Strategy Inc. disclosed on May 18, 2026 that it had acquired 24,869 bitcoin for approximately $2.01 billion between May 11 and May 17. The Form 8-K put the average purchase price at $80,985 per bitcoin, including fees and expenses, and said the purchases were financed with proceeds from securities sold through the company’s at-the-market programs.

The disclosure was consequential because it showed Strategy converting demand for its listed securities into a large, direct purchase of bitcoin even as the company managed a capital structure built around common stock, multiple preferred issues and convertible debt. The event was not a protocol change or a broad market transaction count; it was one public company’s balance-sheet decision, documented in a securities filing.

What the filing establishes

Strategy reported 843,738 BTC in aggregate holdings as of May 17, 2026. It listed an aggregate purchase price of approximately $63.87 billion and an average acquisition cost of $75,700 per bitcoin, both inclusive of fees and expenses. Those are company-reported cost figures, not a mark-to-market valuation.

For the May 11–17 financing window, Strategy reported selling 19,519,801 shares of its variable-rate Series A perpetual Stretch preferred stock, traded as STRC. The sale carried $1.952 billion of notional value and produced $1.949 billion of net proceeds after sales commissions. It also sold 430,344 shares of MSTR common stock for $83.7 million in net proceeds. The filing reported $2.0327 billion in total net proceeds across those sales.

The filing expressly connected the bitcoin purchases to proceeds from the at-the-market share sales. It did not provide timestamps, venues or transaction-by-transaction execution data for the bitcoin acquisitions, so the record supports a weekly aggregate, not a claim about a single trade on May 18.

Why the financing mix mattered

The preferred-stock component supplied roughly 95.9% of the $2.0327 billion of reported net securities-sale proceeds, based on Coinburn’s calculation of $1.949 billion divided by $2.0327 billion. That calculation describes the disclosed funding mix; it does not prove that particular dollars from each issuance can be traced to particular bitcoin purchases.

The structure mattered beyond the headline purchase size. Strategy was using capital-market instruments whose holders had claims and economic exposures different from owning bitcoin directly. STRC was variable-rate perpetual preferred stock, while MSTR represented common equity. Converting proceeds from both into bitcoin enlarged the company’s asset concentration while leaving investors to assess separate dividend, dilution, volatility and corporate-credit risks.

Contemporaneous coverage from The Block and CoinDesk independently reported the 24,869 BTC purchase and the resulting 843,738 BTC balance. Their reports corroborate the filing but do not replace it; the Form 8-K remains the controlling record for the amounts, dates and financing disclosures.

What remained uncertain on May 18

The filing did not establish how the purchase affected Bitcoin’s market price, liquidity or volatility. No causal market claim can be made from the company disclosure alone, especially because Bitcoin trades continuously across many venues and the acquisition window covered seven calendar days. This reconstruction therefore does not pair the announcement with a spot-price move.

The filing also presented “BTC Yield” of 12.6% for 2026 through May 17, but that company-defined performance indicator is not an investment return earned by a shareholder or a bitcoin holder. The central verifiable development on May 18 was narrower: Strategy disclosed a $2.01 billion weekly bitcoin acquisition, funded through at-the-market securities sales, that raised its reported treasury to 843,738 BTC.
