BlackRock has increased its bet on Strategy despite a decline in shares of Michael Saylor’s company. The new $535 million MSTR purchase shows that the world’s largest asset manager continues to show interest in companies whose value is closely tied to Bitcoin.
According to CoinGape, BlackRock bought an additional 3.14 million shares of Strategy in the first quarter of 2026 for about $535.6 million. After the purchase, its stake reached 17.75 million shares, valued at roughly $3.02 billion. That represents a 21.5% increase in BlackRock’s position in Strategy.
For BlackRock, this is not a direct Bitcoin purchase, but an investment in a company that has effectively become a public-market proxy for BTC exposure. Strategy has used capital markets for years to buy cryptocurrency, and its shares often move more sharply than Bitcoin itself because of the company’s debt structure, preferred share issuance and expectations of further BTC purchases.
The disclosure came at a time when MSTR was under pressure. The shares closed at $177.42 on May 15, down $9.55, or 5.11%, for the day. The company’s market capitalization at the time stood at about $62.3 billion, while the value of its Bitcoin reserve was estimated at roughly $62.9 billion.
Coingape also noted that MSTR fell to $170.45 in premarket trading, implying an additional decline of about 3.93%. The stock’s 52-week range remained wide, from $104.16 to $457.22, underscoring its high volatility.
Separately, on May 18, it became known that Strategy had acquired 24,869 BTC for about $2.01 billion at an average price of roughly $80,985 per Bitcoin. After that purchase, the company held 843,738 BTC, acquired for about $63.87 billion at an average price of around $75,700 per BTC.
For the market, this is an important signal: even as MSTR declines, major institutional investors are not stepping away from the Strategy story. BlackRock is increasing its equity stake, while Strategy itself continues to expand its Bitcoin reserve. The risk remains the same: if BTC falls, pressure on MSTR tends to intensify faster. But if demand for Bitcoin recovers, Strategy remains one of the main public-market beneficiaries of that move.
Earlier, we reported that Strategy nears STRC limit as Bitcoin buying may slow.
