Key Takeaways
  • • Brevan Howard reduced its BlackRock iShares Bitcoin Trust (IBIT) position by 70%, from a peak of 37.9 million shares worth $2.3–$2.6 billion in Q2 2025 to approximately 7.2 million shares valued at $240–$255 million as of mid-August 2026.
  • • The firm executed an 86% reduction of spot IBIT holdings in Q4 2025, selling approximately 31.2 million shares worth roughly $275 million, coinciding with a broader Bitcoin market downturn.
  • • Rather than exiting Bitcoin exposure entirely, Brevan Howard shifted strategy to a layered options overlay, acquiring call options on approximately 8 million IBIT shares (notional value exceeding $400 million) and put options on roughly 5 million shares (notional value over $248 million).
  • • Brevan Howard's dedicated crypto strategy posted a 30% loss for the full year 2025, reflecting significant losses on its Bitcoin positions amid volatile market conditions.
  • • The timing of the firm's aggressive position-building in Q2 2025—nearly doubling its IBIT stake immediately before the subsequent market downturn—highlighted poor execution on directional timing for one of the world's most prominent macro hedge funds.
Summary
Brevan Howard, a major institutional player in macro investing, has substantially de-risked its direct Bitcoin exposure while maintaining upside participation through derivative strategies. The hedge fund reduced its stake in BlackRock's iShares Bitcoin Trust by approximately 70%, bringing its spot holdings down to $255 million from a peak position of $2.3–$2.6 billion in the second quarter of 2025.

The reduction was not gradual. The bulk of the selling occurred in Q4 2025, when Brevan Howard liquidated approximately 31.2 million IBIT shares—an 86% cut to its spot position—bringing direct holdings to roughly 5.2 million shares. This timing coincided with a broader downturn in Bitcoin prices, and the firm's performance reflects the impact: its dedicated crypto strategy lost 30% for the full year 2025.

Rather than abandoning Bitcoin entirely, Brevan Howard has reoriented its exposure toward options-based hedging and leverage. The firm now maintains call options on approximately 8 million IBIT shares, representing notional exposure exceeding $400 million, alongside put options covering roughly 5 million shares worth over $248 million in notional value. This shift from spot holdings to optionality suggests the firm is managing downside risk while preserving leverage to potential Bitcoin rallies.

The fund's positioning reveals the execution risk inherent in macro directional bets. In Q2 2025, Brevan Howard nearly doubled its IBIT position immediately ahead of the subsequent market decline, illustrating a significant timing miss on a highly volatile asset class. The subsequent 70% reduction of spot holdings and pivot to options reflects both losses crystallized and a repositioning toward lower-volatility exposure mechanisms. As of mid-August 2026, the firm's remaining direct IBIT stake has stabilized at approximately 7.2 million shares, valued between $240 million and $255 million.
