Strategy bought 13,627 bitcoin last week for about $1.25 billion, marking its largest purchase since July 2025.

The company disclosed in a Form 9-K filing that it now holds 687,410 BTC, acquired at an aggregate cost of roughly $51.8 billion.

Purchase details

Strategy said the latest batch was bought at an average price of $91,519 per bitcoin.

That sits above the company’s overall average cost basis of $75,353.

Funding via equity programs

The filing said the purchases were funded through Strategy’s at-the-market equity programs.

These included sales of MSTR common stock and STRC Variable Rate Series A Perpetual Stretch Preferred Stock.

Strategy said it raised about $1.25 billion in net proceeds and used the funds to buy bitcoin from Jan. 5 through Jan. 11.

The company added that its reported aggregate and average purchase prices included fees and expenses.

Buying through drawdowns

The latest buy followed Strategy’s first bitcoin purchase of 2026, when it bought 1,283 BTC for $116 million on Jan. 5.

That disclosure came alongside reporting of a $17.4 billion unrealized loss on its bitcoin holdings in the fourth quarter of 2025 after prices fell more than 20% late last year.

Strategy said it continued issuing equity and kept cash reserves to service dividends and other obligations despite the paper losses.

The company stated in its filing:

“The company still retains substantial issuance capacity across its common and preferred stock programs.”
