According to a Feb. 6 filing with the US Securities and Exchange Commission (SEC), BlackRock has expanded its stake in Strategy (formerly MicroStrategy) to 5%.

The asset manager now owns around 11.2 million shares, increasing its position from 4.09% in September 2024. With Strategy’s stock trading near $334, BlackRock’s total stake exceeds $3.6 billion in value.

The move means BlackRock is now among Strategy’s largest shareholders. Other major investors include Capital International Investors and Vanguard Group, each holding more than 7% of the Bitcoin-focused company.

This disclosure follows Strategy’s recent rebranding to strengthen its identity as the top corporate holder of Bitcoin. The company currently holds 471,107 BTC, valued at over $46 billion at current market prices.

Market observers noted that BlackRock’s increased stake not only boosts its exposure to Bitcoin but also reflects its growing influence in the crypto market. BlackRock is the issuer of IBIT, the largest spot Bitcoin ETF, and has recently touted the importance of investing in Bitcoin.
