Michael Saylor’s Strategy bought 641 Bitcoin a day in 2025

Michael Saylor-led Strategy (formerly MicroStrategy) has continued its aggressive Bitcoin (BTC) accumulation campaign, adding another 10,645 BTC in the last week as the company steadily expanded its exposure.

According to Finbold Research, which analyzed Strategy’s disclosed Bitcoin purchases throughout 2025, the company acquired a total of 223,800 BTC year to date. Based on weekly purchase data tracked and company filings, Strategy’s Bitcoin buys this year were executed at a weighted average price of $99,908 per BTC.

In its latest acquisition, disclosed in a Form 8-K filed on December 15, 2025, Strategy purchased 10,645 Bitcoin for approximately $980.3 million at an average price of $92,098 per BTC. Following the transaction, the company’s total Bitcoin holdings rose to 671,268 BTC.

At current market prices, Strategy’s Bitcoin treasury is valued at roughly $60.05 billion. The company’s lifetime average Bitcoin purchase price now stands at $74,972, leaving Strategy with an unrealized profit of approximately $9.73 billion, or 19%, despite the majority of its 2025 purchases being executed at significantly higher price levels.

Finbold Research calculations show that Strategy’s 2025 Bitcoin acquisitions translate to an average buying pace of approximately 641 Bitcoin per day between January 6 and December 14. On an hourly basis, the company added close to 27 Bitcoin, reflecting a highly consistent accumulation strategy rather than opportunistic market timing.

Strategy buys Bitcoin in 41 separate weeks

Throughout the year, Strategy carried out purchases across 41 separate weekly reporting periods, with only a single week showing no additional Bitcoin acquired. The data indicates that Strategy continued buying during periods of both price strength and short term consolidation, reinforcing the firm’s long stated view of Bitcoin as a long term treasury reserve asset.

Notably, a substantial portion of Strategy’s 2025 Bitcoin purchases occurred at prices above $100,000, including several weekly acquisitions in the $110,000 to $120,000 range. Despite this, the company’s overall cost basis remains well below current levels due to earlier accumulation cycles, allowing Strategy to maintain a sizable unrealized gain.

With 671,268 BTC on its balance sheet, Strategy remains one of the largest corporate holders of Bitcoin globally. While spot Bitcoin ETF inflows have dominated institutional adoption narratives in 2025, Strategy’s direct and consistent Bitcoin purchases continue to represent a significant and independent source of demand.

With more than 223,000 Bitcoin added this year alone at an average price near $100,000, Strategy appears positioned to remain a central figure in Bitcoin’s corporate ownership landscape heading into 2026.
