U.S. Spot Bitcoin ETFs Post Record $6.35B 30-Day Outflow as BTC Slides

U.S. spot Bitcoin ETFs just logged their largest 30-day net outflow since debuting in January 2024, with $6.35 billion leaving the group, according to Galaxy Research. The pullback coincided with a sharp drop in Bitcoin, which fell about 17% over the month and briefly touched four-month lows around $60,000 to $61,300 in early June. Galaxy's data shows the record outflow was the top reading among 582 rolling 30-day windows tracked by the firm. A key driver was a 13-day redemption streak from May 15 through June 3, when investors withdrew roughly $4.4 billion, equivalent to about 59,400 BTC based on prices during that span. Outflows later eased, with ETFs posting a modest $3 million net inflow around June 4 and June 5, though weekly redemptions continued, including one week that saw $1.7 billion pulled. The largest daily withdrawals were concentrated in the biggest products, including BlackRock's iShares Bitcoin Trust (IBIT) and Fidelity's Wise Origin Bitcoin Fund (FBTC), as institutional investors reduced exposure across multiple ETFs. Even after the recent wave of redemptions, U.S. spot Bitcoin ETFs still show more than $53 billion in cumulative net inflows. The latest withdrawals brought cumulative net flows down to about $53.4 billion from a peak near $63 billion in October 2025. Bloomberg ETF analyst Eric Balchunas described the outflow levels as "noise" within typical ETF activity, as markets watch whether institutional demand continues to cool.
