Strategy acquired 950 BTC between September 14 and September 20 at an average price of $79,670 per coin, including fees and expenses, according to a September 21 filing with the US Securities and Exchange Commission. The filing identifies "USD Cash" as the source of the $75.7 million purchase and does not connect the acquisition to any stock or debt sale completed during the same reporting period. In other words, the latest coins were bought with cash on hand rather than proceeds from share sales.

A cash-funded purchase with no ATM proceeds

The company also reported no sales through its at-the-market (ATM) programs that week. These programs allow the company to sell common or preferred shares gradually at prevailing market prices. In this case, Strategy added Bitcoin without recording fresh ATM proceeds alongside the purchase, showing that it can keep accumulating without drawing on equity sales in every reporting period.

Latest batch bought below market price

Bitcoin traded near $85,000 at approximately 12:15 UTC on September 21 after moving above its May 2026 high. That market price was about 6.% above the $79,670 average Strategy paid for its latest batch. The difference is not a realized profit, because Strategy continues to hold the coins; it only compares the market price at that moment with the average cost of the 950 BTC acquired before September 21.

The purchase lifted Strategy's position by roughly 0.1%, so it did not materially change the company's exposure to Bitcoin. For scale, privately held SpaceX reportedly owns 18,712 BTC, while Strategy's 846,000 BTC position is more than 45 times larger.

In a post on X, Michael S confirmed both transactions:

Strategy has acquired 950 $BTC and repurchased $174M of $STRC. As of 9/20/26, we hold 846,000 BTC and $6.09B of USD Assets. $MSTR

Total Bitcoin cost reaches $63.8 billion

The filing places Strategy's aggregate Bitcoin acquisition cost at $63.8 billion, with an overall average purchase price of $75,416 per coin, including fees and expenses. At $85,000 per Bitcoin, the 846,000-coin position would be worth approximately $71.9 billion — about $8.1 billion, or 12.7%, above the reported cost basis. Both figures are unrealized and would change immediately with Bitcoin's price.

Strategy ended September 20 with $1.05 billion in USD Cash and a separate $5.04 billion reserve earmarked for preferred-stock dividends and interest payments. During the week, it used $57.4 million from that reserve for dividends and debt interest — a draw equal to roughly 1.1% of the reserve's ending balance.

Financing choice matters more than purchase size

The 950 BTC addition was small beside Strategy's existing holdings. The more revealing part of the filing is how the company allocated its cash while making the purchase. Strategy spent $174 million repurchasing 1.77 million shares of its STRC preferred stock — more than twice the amount spent on Bitcoin. The filing therefore records two separate uses of cash: expanding the BTC position and reducing the amount of STRC outstanding.

STRC sits within Strategy's preferred-stock lineup, a class of shares that ranks ahead of common stock in the capital structure and carries fixed dividend commitments. Because those commitments recur, a smaller outstanding count means a smaller aggregate claim on the reserve the company maintains for such payments.

One week does not establish a new financing pattern. However, the purchase shows that Strategy can continue adding Bitcoin without relying on ATM sales in every reporting period. Its next filing will indicate whether this was an isolated cash-funded acquisition or part of a longer sequence.
