Which Funds Lead in Capital Outflows
The largest share of the outflow was from the iShares Bitcoin Trust ETF (IBIT) by BlackRock — $527.84 million. Investors withdrew an additional $104.76 million from the Grayscale Bitcoin Trust ETF (GBTC), and $60.3 million from the Fidelity Wise Origin Bitcoin Fund (FBTC).
A similar trend is observed among Ethereum-based products. Over 12 consecutive trading days, approximately $570 million was withdrawn from Ethereum ETFs, with investors leaving these funds by $67.15 million on May 27 alone. Withdrawals from ETHA amounted to $65.1 million, while FETH saw $2.05 million withdrawn.
Analysts’ Assessments and Potential Risks
“Wintermute analysts previously stated that the key issue for the market remains the flows into spot Bitcoin ETFs. According to them, these products have shown significant outflows in recent weeks.”
Experts believe that institutional demand, which previously stimulated the Bitcoin market, has significantly weakened. Analysts emphasize that some risk capital has shifted from cryptocurrencies to traditional stocks.
Swissblock points out that the risk index for Bitcoin is approaching a zone of increased danger due to prolonged deterioration in inflows into spot Bitcoin ETFs. Their observations suggest that this dynamic may indicate institutional distribution — when selling pressure in the market outweighs demand. Despite this, since the beginning of 2026, spot Bitcoin ETFs have remained in a zone of net inflow, although this figure has decreased to approximately 4500 BTC.
Timothy Misir, head of research at BRN, believes that the outflow of funds from Bitcoin ETFs does not signify a complete exit of institutional players from the market. Previously, from May 18 to 22, 2026, spot Bitcoin ETFs in the US recorded a significant weekly outflow of $1.26 billion, marking the fourth largest figure in the history of the segment and the third such case in 2026.
