US spot Bitcoin ETFs just logged their worst 30-day stretch since they debuted in January 2024, with cumulative outflows reaching approximately $6 billion across recent months as Bitcoin’s price cratered 17% over the past month.
The bleeding was most acute during a 13-day consecutive outflow streak from May 15 through June 3, which alone accounted for roughly $4.4 billion in net redemptions. In Bitcoin terms, that’s about 59,400 BTC walking out the door.
Where the money went
The outflows weren’t evenly distributed across the dozen-odd spot Bitcoin ETF products. The pain was concentrated in the two biggest funds: BlackRock’s IBIT and Fidelity’s FBTC, which saw peak daily redemptions in the hundreds of millions of dollars.
The streak finally snapped with a modest net inflow of $3 million around June 4-5. Weekly outflows remained considerable even after the streak ended, with one week alone seeing $1.7 billion in net redemptions.
Bitcoin’s price reflected the selling pressure, dropping to four-month lows in the $60,000 to $61,300 range in early June.
Why institutions hit the sell button
Three forces converged to create this perfect storm of outflows. First, plain old profit-taking. Many institutional players who entered Bitcoin ETF positions in 2024 or early 2025 were sitting on substantial gains, even after the recent decline. Second, macroeconomic uncertainty. Third, a general cooling of risk appetite.
Bloomberg ETF analyst Eric Balchunas characterized the outflow levels as “noise” within the broader context of institutional adoption and typical ETF volatility.
What this means for investors
The $6 billion in cumulative outflows needs to be weighed against the full picture. Since their launch in January 2024, spot Bitcoin ETFs have attracted cumulative net inflows exceeding $50 to $60 billion. The recent selling represents a single-digit percentage of total capital that has flowed into these products.
Year-to-date flows for 2026 were hovering near breakeven before the May-June streak hit.
For traders, the immediate concern is volatility. Large ETF redemptions create selling pressure on spot Bitcoin markets because ETF issuers must sell their underlying Bitcoin holdings to meet withdrawals.
