U.S. spot crypto ETFs suffered another heavy redemption session on May 27, with Bitcoin and Ethereum funds losing a combined $800.5 million as institutional demand weakened into the latest market pullback.
The Bitcoin ETF flow table shows $733.4 million in net outflows on May 27. BlackRock’s IBIT carried most of the pressure with $527.8 million leaving the fund, followed by $104.8 million from Grayscale’s GBTC, $60.3 million from Fidelity’s FBTC, $17.5 million from Bitwise’s BITB, $17.4 million from ARK 21Shares’ ARKB and $9.9 million from Grayscale’s BTC. Morgan Stanley’s MSBT was the only Bitcoin ETF to post a net inflow, adding $4.3 million.
Ethereum ETFs added another $67.1 million in outflows. The Ethereum ETF flow table shows BlackRock’s ETHA losing $65.1 million, while Fidelity’s FETH lost $2 million. The rest of the listed Ethereum products were flat on the day, leaving ETHA responsible for nearly the entire ETH ETF redemption print.
The daily combined total puts the pressure in clear terms: Bitcoin funds lost $733.4 million, Ethereum funds lost $67.1 million, and the two largest U.S. spot crypto ETF categories lost $800.5 million together in a single trading session.
Two-Day Outflows Near $1.17B
The May 27 move extended a rough two-day stretch for crypto ETFs. Bitcoin funds lost $333.6 million on May 26 and $733.4 million on May 27, bringing two-day BTC ETF outflows to $1.067 billion. Ethereum funds lost $35.1 million on May 26 and $67.1 million on May 27, bringing two-day ETH ETF outflows to $102.2 million.
Together, spot Bitcoin and Ethereum ETFs lost about $1.169 billion across the two sessions. That is a meaningful liquidity drain at a time when Bitcoin is already testing key support and Ethereum has slipped below the $2,000 level.
The flow picture lines up with the broader market reset. Bitcoin is sitting near a major $73,000 to $71,300 support zone as traders watch whether the February ascending channel can hold. Ethereum’s break below $2,000 has also triggered a sharp sentiment shift, with retail buy-the-dip calls rising even as price action remains weak.
Sentiment has already deteriorated. The Crypto Fear & Greed Index dropped to extreme fear, while sticky April PCE inflation has added pressure to risk assets by keeping the Fed’s rate-cut path uncertain.
The ETF market now becomes one of the clearest short-term signals for Bitcoin and Ethereum. A return to inflows would help stabilize support and improve confidence around the current pullback. Continued redemptions from IBIT, FBTC, GBTC, ETHA and other large funds would keep pressure on spot demand and leave crypto more exposed to another leg lower if key support levels fail.
