Strategy holds a record 847,666 BTC after buying 1,665 Bitcoin for $142.7 million between September 21 and September 27, according to a Monday filing with the Securities and Exchange Commission.

The company paid an average of $85,681 per coin. Its cumulative position, acquired for $63.95 billion, carries an average cost basis of $75,437 per Bitcoin. The new total eclipses Strategy's previous record of 847,363 BTC, set on June 22, per BitcoinTreasuries data.

The purchase marks a second consecutive week of net Bitcoin buying after a summer in which the company moved in the opposite direction. Strategy sold 6,948 BTC between May and August, according to earlier disclosures, while building up its dollar reserves. It resumed purchases in August.

The company confirmed the move on X: "Strategy has acquired 1,665 $BTC and repurchased $152M of $STRC. As of 9/27/26, we hold 847,666 BTC and $6.02B of USD Assets."

How did Strategy fund the purchase?

The company financed the acquisition through its at-the-market equity program. It sold 1.47 million MSTR common shares during the week, generating $246.2 million in net proceeds. It allocated $142.7 million to Bitcoin purchases and directed $103.5 million toward repurchases of STRC preferred stock.

The structure shows Strategy managing two capital priorities at once: accumulating Bitcoin and retiring preferred equity trading below its stated value.

What is happening with STRC buybacks?

Alongside the Bitcoin purchase, Strategy repurchased 1.53 million shares of its Variable Rate Series A Perpetual Stretch Preferred Stock, ticker STRC, for $151.7 million in total.

The buybacks form part of a broader capital-allocation strategy the company has laid out in previous filings. Strategy has now spent hundreds of millions of dollars repurchasing STRC to capture the discount to its stated amount. The latest filing reports $723.5 million still available under its digital credit securities repurchase program.

Last week, the firm proposed daily dividend accrual on its preferred stock — including STRF, STRC, SREK and STRD — in an effort to dampen volatility in those instruments.

How large are Strategy's dollar reserves?

The 8-K discloses $6.02 billion in USD assets as of September 27, split between a $5.02 billion USD Reserve and $1 billion of USD Cash.

The two pools serve distinct functions. The USD Reserve backs preferred-stock dividends and interest on debt. The company established the separate USD Cash facility last month for Bitcoin purchases, reserve increases and other capital-management purposes.

During the latest week, Strategy drew $48.1 million from USD Cash to fund STRC repurchases and used $22.1 million from the USD Reserve to pay preferred-stock dividends.

The company has stated its capital framework permits selling up to $1.25 billion of Bitcoin to fund the USD Reserve, preferred dividends, interest expenses and buybacks of MSTR or its preferred securities — a buffer that remains available if market conditions force it back into distribution mode.

For now, the disclosure shows Strategy on the buy side of both markets. With 847,666 BTC on its balance sheet and $723.5 million of remaining authorization under the STRC repurchase program, the company enters October with record Bitcoin exposure and multiple active channels for deploying its $6.02 billion dollar position.
