Bitcoin ETFs have experienced their largest outflow on record, with more than 100,000 BTC leaving ETF holdings in 2026 alone. Since ETF Bitcoin holdings peaked in October 2025, total outflows have exceeded 160,000 BTC, representing the largest drawdown since spot ETFs launched. With an estimated average acquisition price near $73,000, many ETF-held Bitcoin positions are now underwater. Investors will watch whether ETF flows stabilize or continue to weigh on Bitcoin prices.
