Strategy crossed 500,000 bitcoin after a $584.1 million purchase

Strategy disclosed on March 24, 2025 that it had acquired approximately 6,911 bitcoin for $584.1 million in cash, taking the company’s total holdings above 500,000 BTC for the first time.

The purchase occurred between March 17 and March 23, 2025 at an average acquisition price of approximately $84,529 per bitcoin, including fees and expenses, according to the company’s Form 8-K filed with the U.S. Securities and Exchange Commission. As of March 23, Strategy and its subsidiaries held approximately 506,137 BTC acquired for an aggregate purchase price of about $33.7 billion, or an average of approximately $66,608 per bitcoin.

The disclosure mattered because it documented both the scale of Strategy’s bitcoin concentration and the capital-markets mechanism supporting it. The company was no longer using only accumulated corporate cash to expand its treasury. It was selling securities and directing much of the resulting capital into bitcoin.

Share sales financed the acquisition

Strategy reported selling 1,975,000 shares of MSTR class A common stock between March 17 and March 23 through an at-the-market offering program. Those sales produced approximately $592.6 million in net proceeds after sales commissions. The company also sold 13,100 shares of its 8% Series A perpetual strike preferred stock, traded as STRK, for approximately $1.1 million in net proceeds.

The filing states that proceeds from those two programs funded the bitcoin purchases. As of March 23, approximately $3.57 billion of common shares and $20.99 billion of STRK preferred shares remained available for issuance under the respective programs.

An at-the-market program permits securities to be sold into the market over time; the disclosed net proceeds do not represent a single block transaction or one uniform sale price. For existing shareholders, continued common-stock issuance could expand the share count, while preferred issuance added a separate security with its own dividend claim. The bitcoin acquisition therefore increased the company’s digital-asset exposure while also changing its capital structure.

The half-million threshold

Strategy’s March 17 SEC filing had placed its holdings at 499,226 BTC as of March 16, following a much smaller purchase of 130 BTC for approximately $10.7 million. The 6,911-BTC acquisition disclosed on March 24 moved the reported balance to 506,137 BTC, or 6,137 BTC above the half-million threshold.

Dividing 506,137 by Bitcoin’s 21 million maximum supply produces approximately 2.41%. That calculation is a comparison with the protocol’s eventual supply ceiling, not a measure of circulating liquidity, coins available for sale, voting power or control over the network.

The acquisition price also requires care. The reported $84,529 figure was Strategy’s fee-inclusive average for purchases made from March 17 through March 23. It was not a March 24 spot-market opening or closing price. The filing did not disclose individual execution times, trading venues, counterparties or per-trade prices, preventing an independent reconstruction of execution quality.

Why the disclosure mattered

The verified development was not simply that one company bought more bitcoin. Strategy demonstrated that public equity and preferred-stock markets could serve as repeatable funding channels for a concentrated corporate bitcoin policy. That model linked the interests of bitcoin holders, MSTR shareholders and preferred investors through the same balance sheet.

For the bitcoin market, the disclosure identified a large corporate buyer over a precise seven-day window, but it did not prove that the purchases caused any particular market movement. For equity investors, the filing reinforced that MSTR exposure depended on bitcoin prices, financing conditions and future securities issuance in addition to the company’s operating business.

What was knowable on March 24, 2025 was therefore narrow but significant: Strategy reported holding 506,137 BTC, disclosed how the latest purchase was financed and retained substantial capacity to issue additional securities. Future purchases, valuations and financing outcomes remained uncertain.
