Macro hedge fund Brevan Howard disclosed a $2.3 billion position in BlackRock’s Bitcoin ETF, representing over 20% of its total portfolio holdings.
Brevan Howard, often described as one of the largest “macro hedge funds” in the world, disclosed a stake of $2.30 billion in BlackRock‘s iShares Bitcoin Trust ETF on August 15, reportedly accounting for over 20% of its portfolio. The disclosure comes while BTC tanks in price, retracing back to $117,000 after making a new all-time high above $124,500.
Notably, the multi-billion-dollar hedge fund waited until the last day to submit its 2025 Q2 Form 13F to the Securities and Exchange Commission (SEC) of the United States, containing the surprisingly high allocation in BlackRock’s Bitcoin ETF. Form 13F is a quarterly report for institutional investment managers that exercise investment discretion over $100 million and must be presented within a maximum of 45 days after the end of each calendar quarter—which ended on June 30.
The filings reveal three separate entries for the iShares Bitcoin Trust ETF (IBIT) totaling $2.26 billion, $32.86 million, and $24.48 million. Additionally, the documents show an $800,000 allocation in the iShares Ethereum Trust ETF (ETHA).
