U.S. Spot Bitcoin ETFs Post Biggest One-Day Outflow Since Jan. 29, 2026

BlockBeats reported that on May 19, U.S. spot Bitcoin ETFs saw net redemptions of about $648.6 million, the largest single-day outflow since Jan. 29, 2026. The move extends last week's roughly $1 billion in net outflows. BlackRock's iShares Bitcoin Trust (IBIT) led the day's selling with around $448.3 million in net outflows. ARK 21Shares Bitcoin ETF (ARKB) and Fidelity Wise Origin Bitcoin Fund (FBTC) followed. Bitwise, VanEck, Invesco and Franklin Templeton products also reported withdrawals. Analysts attributed the pullback to renewed risk aversion amid escalating U.S.-Iran geopolitical tensions, higher oil prices and rising long-term U.S. Treasury yields, which have amplified concerns about sticky inflation and encouraged short-term profit-taking by some institutions. Higher risk-free yields have also reduced the relative appeal of Bitcoin ETFs for institutional allocators. Despite elevated near-term volatility, some analysts said Bitcoin's broader structural uptrend remains intact. They added that the continued expansion in stablecoin market capitalization suggests sidelined capital may still be waiting to enter at lower levels.
