Bitcoin and Ether ETFs Shed $159M as Institutional Rebound Stalls

U.S. spot Bitcoin and Ether ETFs recorded $159.2 million in combined net outflows on Monday, abruptly interrupting a rebound that had brought more than $1.1 billion into the products during the previous week.

Bitcoin funds accounted for most of the reversal. Farside data show the group lost $144.6 million on August 10, ending a five-session inflow streak. BlackRock’s IBIT posted $53.6 million in redemptions, Fidelity’s FBTC lost $40.3 million and Bitwise’s BITB shed $28.4 million. Grayscale’s GBTC recorded another $52 million outflow, partly offset by a $37.1 million inflow into its smaller BTC fund.

Ether ETFs finished the session with a smaller $14.6 million net outflow, ending four consecutive positive trading days. BlackRock’s ETHA lost $23.8 million and Fidelity’s FETH shed $3.3 million, while BlackRock’s ETHB attracted $3.9 million and Grayscale’s Ethereum Mini Trust added $8.6 million, according to Farside’s Ether flows.

BlackRock funds reverse after dominating inflows

The reversal was particularly sharp for BlackRock. Its Bitcoin and Ether funds recorded $77.4 million in combined outflows Monday after accounting for roughly 81% of the previous week’s $1.11 billion inflow. IBIT and ETHA alone had attracted about $896.5 million between August 3 and August 7.

Monday’s withdrawals amount to roughly 14% of the capital added during that week, so the rebound has not been erased. They do, however, break the synchronized inflow pattern that had provided the clearest sign of renewed institutional demand since April.

Bitcoin ETFs were still about $4.44 billion in net outflows for 2026 through Friday, while Ether funds were down roughly $873 million. Including Monday’s withdrawals would deepen those deficits to approximately $4.58 billion and $888 million, respectively.
