US Spot Bitcoin ETFs faced significant outflows totaling $616.1 million on May 30, 2025, with BlackRock's iShares Bitcoin Trust (IBIT) accounting for $430.8 million. This marked IBIT's largest single-day outflow since its inception in January 2024, ending a 31-day inflow streak. The outflows occurred after a period of strong inflows, with US Bitcoin ETFs attracting $2.75 billion in the week ending May 23. Despite the sell-off, Bitcoin's price remained 9% higher than a month earlier, though it dropped 2.3% on May 30, partly due to the ETF redemptions.
