Strategy expanded its Bitcoin treasury again last week, buying 17,994 BTC for about $1.28 billion. The purchase lifted its total holdings to 738,731 BTC, according to the company’s March 9 filing with the US Securities and Exchange Commission.
Strategy said it paid an average of $70,946 per coin in the latest transaction, while its full Bitcoin stack carries an average acquisition cost of $75,862 per coin.
The filing places strategy even deeper at the center of the corporate Bitcoin market. Executive Chairman Michael Saylor has continued to position the company around Bitcoin accumulation, using capital markets activity to fund purchases. On Monday, MSTR shares traded at about $138.29, up nearly 3.5% intraday, while Bitcoin changed hands near $68,960.
Strategy said the latest purchase took place between March 2 and March 8. The company spent nearly $1.28 billion on 17,994 BTC during that period. The filing also states that Strategy’s total Bitcoin holdings now stand at 738,731 BTC, acquired for about $56.04 billion in total.
Those figures matter because they show the scale of Strategy’s treasury model. The company is no longer making occasional Bitcoin buys. It is adding large blocks of BTC regularly and reporting them through its public filings and treasury dashboard. Strategy’s purchase page also reflects the updated total and average cost basis disclosed on March 9.
Strategy financed the latest acquisition through share sales. The company disclosed that it sold 6,327,541 Class A common shares, which generated about $899.5 million in net proceeds. It also sold 3,776,205 shares of its variable-rate Series A Perpetual Stretch Preferred Stock, producing about $377.1 million in net proceeds. Combined, those proceeds closely matched the amount used for the Bitcoin purchase.
The filing also shows that Strategy amended its Omnibus Sales Agreement. The revision allows the company to appoint a second sales agent for the same security class outside regular market hours, specifically before 9:30 a.m. and after 4:00 p.m. New York time. The change gives Strategy more flexibility as it continues to raise capital through at-the-market programs.
The latest filing reinforces Strategy’s long-running position that Bitcoin serves as its main reserve asset. Saylor summarized the update on social media, stating that Strategy had acquired 17,994 BTC for about $1.28 billion and now holds 738,731 BTC overall. His statement matched the figures reported in the filing.
The new purchase also highlights Strategy’s scale within the Bitcoin market. With 738,731 BTC on its balance sheet, the company remains the largest public corporate holder of Bitcoin by a wide margin. This status keeps MSTR closely tied to Bitcoin price moves, capital raising conditions, and investor demand for Bitcoin-linked corporate exposure. Monday’s market action reflected that connection, with both MSTR stock and Bitcoin trading higher after the disclosure.
