Hedge funds dump bitcoin ETFs as the futures basis trade dries up
Nine hedge funds and banks, including Brevan Howard, reduced their exposure to bitcoin ETFs by 68,000 BTC ($5.4B) from Sep 2025 to Jun 2026. The move followed a decline in the arbitrage opportunity between spot ETFs and futures, not a change in bitcoin's price outlook. CME open interest and net long positions also fell significantly.
