U.S. spot Bitcoin ETFs have just gone through the sharpest withdrawal cycle since their launch. According to a TechFlowPost article by Claude of ShenChao TechFlow, the products recorded 13 straight trading days of net outflows from May 15 to June 3, with total withdrawals of about $4.37 billion, equal to roughly 59,000 Bitcoin. In the article’s framing, that figure is close to $4.4 billion and is more than double the previous record set in February 2025. The outflow streak also pushed the 2026 year-to-date net flow figure into negative territory for the first time.
Thirteen Trading Days and About $4.37 Billion in Withdrawals
The report treats ETF flow data as a direct measure of institutional positioning toward Bitcoin. Spot Bitcoin ETFs buy and sell physical Bitcoin in line with investor creations and redemptions, so inflows and outflows correspond to changes in fund holdings rather than public commentary. Galaxy Research data cited in the article shows that the 13-day outflow run from May 15 to June 3 was the longest continuous withdrawal period since these products listed in January 2024.
The previous record had been eight days and $3.2 billion in February 2025. This latest streak exceeded that mark both in duration and in dollar value. Galaxy Research also noted that outflows across multiple observation windows, including seven-day, ten-day, and twenty-day periods, reached new historical highs during the same span. That pattern indicates that the withdrawals were not concentrated in a single trading session, but extended over a meaningful period. Bloomberg ETF analyst Eric Balchunas confirmed that year-to-date cumulative flows turned negative for the first time during this episode.
The heaviest redemption pressure was concentrated in BlackRock’s IBIT. According to Farside Investors data cited in the report, IBIT alone saw about $3.3 billion in net outflows during the withdrawal period, accounting for three quarters of the total. Fidelity’s FBTC followed with about $456.6 million in outflows, while Grayscale’s GBTC recorded about $303.6 million. IBIT had been the strongest asset gatherer among the spot Bitcoin ETFs since launch, but it became the center of redemptions during this flow reversal.
Total ETF Assets Shrink by About $21.5 Billion in Three Weeks
The impact of fund withdrawals was amplified by the decline in Bitcoin’s price over the same period. The Defiant, citing SoSoValue data, reported that total assets across all U.S. spot Bitcoin ETFs fell from about $104.29 billion on May 15 to about $82.83 billion on June 3. That represents a decrease of roughly $21.5 billion in three weeks.
The article attributes the drop to two overlapping forces: redemptions removed capital directly, while Bitcoin’s decline from above $80,000 to near $63,000 reduced the value of the remaining holdings. The price decline over that span was about 21%. As a result, the funds experienced pressure both from investor withdrawals and from lower mark-to-market values on their Bitcoin positions.
By holdings, the ETFs’ Bitcoin balance fell to about 1.277 million BTC, around 7.2% below the peak reached in October 2025. These ETFs currently hold Bitcoin equal to about 6.36% of Bitcoin’s circulating market capitalization, down from more than 7% at the mid-May high. One redemption stood out on May 28, when BlackRock’s IBIT recorded $527.8 million in single-day net outflows, the second-largest daily redemption in the fund’s history. For the full month of May, U.S. Bitcoin ETFs saw $2.43 billion in net outflows, setting a monthly withdrawal record, with the final week alone contributing $1.42 billion.
June 12 Brings a Clean No-Outflow Session
The turning point appeared in early June. On June 5, Bitcoin ETFs ended the 13-day outflow streak with a modest $3.05 million in net inflows. That amount is small relative to the size of the market, but the direction changed. On the same day, Ethereum ETFs also ended a 17-day outflow streak and recorded $19.3 million in net inflows, all of which came from BlackRock’s ETHA.
The data point cited more directly by institutions came on Friday, June 12. SoSoValue data showed that U.S. spot Bitcoin ETFs posted $85.84 million in single-day net inflows. Five funds recorded inflows, while the other seven showed zero net flow. None of the 12 products posted a net outflow. The original article described this “all zero outflow” condition as a key state for observers assessing whether selling pressure had eased.
Standard Chartered Adds the Flow Shift to Its Bottom Checklist
Geoff Kendrick, global head of digital assets research at Standard Chartered, included the June 12 flow signal in his Bitcoin bottom checklist. In a brief note to clients on Friday, Kendrick said crypto asset prices had already reached the low of this cycle, corresponding to Bitcoin near $59,000, down 53% from the $126,000 high. He listed three indicators to confirm the view: Strategy reported that it bought more Bitcoin the previous week, ETFs recorded positive inflows on Friday, and oil prices continued to move lower.
Kendrick ended the note with the line: “Winter is over, welcome back to crypto spring.” The TechFlowPost article also stressed that a single day of $85.84 million in inflows cannot reverse roughly $4.4 billion in withdrawals over three weeks. Still, a clean trading day with no ETF posting net outflows provides a starting point for observing whether selling pressure has peaked.
ETF flows now have a growing connection with Bitcoin price movement. A calculation cited by Cryptopolitan states that ETF flows can currently explain about 45% of Bitcoin’s weekly price volatility. Since their January 2024 launch, these Bitcoin ETFs still have more than $55 billion in cumulative net inflows and remain less than $10 billion away from their historical peak. Based on that context, Balchunas judged the $4.4 billion outflow to be a meaningful momentum reversal rather than a structural collapse.
