Strategy brings its reserves to 639,835 bitcoins after a new massive acquisition

The machine is well oiled. Strategy shows its claws again and grows its digital treasure like few can. The company led by Michael Saylor pursues a momentum that fascinates as much as it worries. With exploding figures and bold financial strategies, it establishes itself a little more as the “unofficial treasurer” of global bitcoin. While others hesitate, Strategy continues to run the capital printing press to inflate its vaults.

Strategy faces the challenge of the global bitcoin safe

The story accelerates after the recent accumulation of 525 BTC : between September 15 and 21, 2025, Strategy bought 850 BTC for 99.7 million dollars, at an average price of 117,344 dollars per bitcoin. Its total thus climbs to 639,835 BTC , representing more than 72 billion dollars in digital assets.

With more than 3% of the total bitcoin supply, the company occupies an unrivaled place in the ecosystem.

For Michael Saylor, this policy is a creed. Regardless of symbolic exclusions, like the refusal to include the company in the S&P 500, Strategy keeps moving forward. Analysts see it as a risky strategy, but the conviction remains intact: treat bitcoin as a global strategic asset, on par with gold.

This accumulation logic goes beyond mere speculation. It reflects a long-term vision, that of a world where bitcoin becomes a pillar of stability. Beyond politics, Saylor even joined discussions around the BITCOIN Act in Washington, confirming that his mission goes beyond his company’s interests.

The line between private capital and national strategy is increasingly blurred.

BTC and macroeconomics: Strategy navigates global turbulences

This purchase did not happen by chance. It takes place in a context marked by the Fed’s rate cut (-25 basis points). The bitcoin price briefly exceeded 117,000 dollars, confirming its role as a safe haven. Strategy took advantage of this window to consolidate its stock.

The company finances these acquisitions with careful financial engineering: sales of MSTR shares and preferred stock programs STRK, STRF, STRC and STRD. Stated goal: raise 84 billion dollars by 2027 to keep the BTC machine fed.

Key figures to remember

• 850 BTC bought in September for 99.7 M$;
• 639,835 BTC held in total, valued at 72 B$;
• 3% of the global bitcoin supply concentrated at Strategy;
• 84 B$ of planned fundraising by 2027 to finance accumulation.

This strategy comes with a slowdown in pace: 3,330 BTC bought in September, compared to 7,714 in August and 31,466 in July. While other companies like Metaplanet intensify their purchases (5,419 BTC for 632.5 M$ recently), Strategy chooses to anchor its policy in a macroeconomic logic, at the intersection of financial markets and monetary cycles.

A conclusion emerges: bitcoin’s future remains under close watch. For September, some experts predict no spectacular rebound, even if it means consoling themselves with temporary losses. But all eyes turn to October, announced as an explosive month for bitcoin . If the trend holds, the current lull could just be the calm before the storm.
