U.S. spot bitcoin and ether ETFs pulled $2.6 billion last week. That is their strongest combined inflow since October 2025. Trading volume more than tripled to $29 billion during a rally that handed both assets their largest weekly gain in two years.
The inflows reversed $392 million in outflows from the prior week. They more than doubled the $1.1 billion recorded during the week ending Aug. 7, according to SoSoValue data analyzed by The Block. Bitcoin ETFs drew $1.9 billion. Ether ETFs took $697.2 million. Both were each category’s largest weekly haul of 2026. The swing from net outflows to net inflows ran roughly $3 billion week over week.
For bitcoin ETFs, the $1.9 billion was the biggest weekly total since the week ending Oct. 10, 2025, when the category pulled $2.7 billion. Cumulative net inflows since the products launched now stand at $53.7 billion. The Aug. 7 result, at $1.1 billion, had been the strongest for both categories since April. Last week doubled it.
Trading volume climbed harder than flows. Bitcoin ETF turnover rose to $22.1 billion from $6.9 billion the prior week, a 219% jump. Ether ETF volume climbed to $6.9 billion from $1.9 billion, up 259%. Combined weekly volume reached roughly $29 billion, up from $8.8 billion the week before.
Much of the buying landed midweek. Wednesday logged $517.2 million, the largest single-day inflow since May 4. Thursday topped that at $606.3 million, led by $503 million into BlackRock’s iShares Bitcoin Trust (IBIT) alone. The two sessions together accounted for over $1.1 billion of the week’s total.
The volume surge tracked price. Bitcoin briefly traded above $79,000 on Friday during its largest weekly gain in two years, per The Block’s price pages. Both assets gained between 24% and 28% over the week. At press time Saturday afternoon, bitcoin sat near $77,200, off Friday’s peak. Ether changed hands around $2,423.
Ether’s flows held their own. The $697.2 million was the category’s largest weekly inflow since the week ending Oct. 3, 2025, when ether ETFs drew nearly $1.3 billion. The prior week had produced a near-flat $2.3 million in net outflows for the ether category. Ether ETF cumulative net inflows since launch stand at $12.2 billion.
Net assets climbed 35.9% to $14.3 billion from $10.5 billion. That figure reflects both fresh inflows and ether’s price appreciation over the week. Ether ETF assets now exceed cumulative net inflows by roughly $2.1 billion. Two weeks earlier, the category’s net assets sat about $711 million below its cumulative inflow total. Price gains compounded on top of new money entering the funds and flipped the gap.
Bitcoin ETF assets under management rose 25.4% to $96.1 billion from $76.6 billion over the week. Inflows and bitcoin’s price move drove the increase.
The rally did not erase the year’s deficit. Bitcoin ETFs remain roughly $2.9 billion net negative for 2026. Ether ETFs are down about $191.8 million year-to-date. The combined annual shortfall narrowed from $5.7 billion to $3.1 billion. The week’s $2.6 billion in inflows matched the reduction almost dollar for dollar. One strong week cut the gap nearly in half. It did not close it.
