U.S. spot Bitcoin and Ethereum ETFs shed nearly $900 million in combined net outflows over three trading sessions from May 13 to May 15, 2026, as both assets failed to break out of a narrow trading range and institutional investors pulled back sharply.
Three Days of Redemptions Across Both Products
The selling started on May 13, when U.S. spot Bitcoin ETFs posted -$630.4 million in net outflows, the largest single-day exit in three months. BlackRock's IBIT accounted for -$284.7 million of that total, followed by ARKB at -$177.1 million and FBTC at -$133.2 million.
Ethereum ETFs saw a smaller but parallel move, recording -$36.3 million in net outflows on the same day. The simultaneous weakness across both products pointed to broad risk-off positioning rather than a single-asset rotation.
Bitcoin ETFs briefly reversed course on May 14 with $131.3 million in inflows, but the reprieve was short-lived. By May 15, another -$290.4 million flowed out of Bitcoin funds while Ethereum ETFs lost -$65.7 million, bringing the three-session combined total to roughly $897 million in net redemptions.
The May 13 washout reversed a five-week inflow streak worth approximately $3.8 billion through the week ending May 6, according to reporting from Decrypt. That reversal underscored how quickly institutional sentiment can shift when momentum fades.
Flat Prices Reinforced the Exit Signal
Bitcoin traded near $77,937 with a 24-hour change of just -0.4% at the time of research, while Ethereum hovered around $2,178, essentially flat. The lack of price follow-through gave momentum-driven participants little reason to stay.
Stalled prices and rising redemptions tend to feed on each other. When ETF holders see flat performance alongside heavy outflows, conviction erodes, which can trigger further selling. The Fear & Greed Index sat at 27, firmly in "Fear" territory, reflecting the cautious mood across the broader market.
Illia Otychenko, an analyst quoted by Decrypt, noted that "a large part of the outflows was driven by this week's U.S. inflation data, which significantly shifted market expectations around Federal Reserve policy." That macro backdrop helps explain why the selling hit both Bitcoin and Ethereum funds simultaneously rather than affecting just one asset.
The pattern contrasts with recent weeks when spot XRP ETFs were posting their strongest weekly flows since December, and when corporate buyers like Michael Saylor were signaling fresh Bitcoin accumulation. That divergence suggests the current pullback may be more about macro timing than a structural shift in crypto ETF demand.
What Comes Next for ETF Flows
The most immediate signal to watch is whether redemptions persist into the following week or reverse. A return to net inflows would suggest the three-day drawdown was a positioning adjustment tied to the inflation print rather than a lasting sentiment shift.
On the price side, Bitcoin's ability to hold above the $77,000 level or break decisively below it will likely influence how ETF allocators behave. A clean breakout above recent resistance could pull sidelined capital back in, while a sustained breakdown might accelerate outflows further.
For Ethereum, the picture is complicated by the asset's underperformance relative to Bitcoin for most of 2026. Ethereum ETF flows have been consistently smaller in magnitude, and the evolving U.S. regulatory landscape around digital asset classification adds another layer of uncertainty for institutional allocators sizing positions in ETH-based products.
