U.S. spot bitcoin and ether exchange-traded funds took in a combined $2.6 billion in net inflows last week, their strongest week since October 2025, according to SoSoValue data.
Spot bitcoin ETFs accounted for $1.9 billion of that total, while spot ether ETFs drew $697.2 million, their biggest weekly inflow of the year. Compared with the previous week, when the two categories posted a combined $392 million in net outflows, the turnaround was roughly $3 billion.
Last week’s total was also more than double the $1.1 billion brought in during the week ending Aug. 7, which had been the best result for both categories since April.
Bitcoin ETFs logged inflows in every session
Bitcoin funds recorded net inflows across all five trading sessions last week. The high point came on Thursday, when they pulled in $606.3 million. Of that amount, $503 million went to BlackRock’s iShares Bitcoin Trust.
Bitcoin moved above $79,000 on Friday as bitcoin ETF trading volume climbed to $22.1 billion, up from $6.9 billion a week earlier. Assets under management for bitcoin ETFs increased 25.4% to $96.1 billion from $76.6 billion.
Ether ETF volumes and assets also climbed
Ether funds followed the same pattern. Weekly trading volume rose to $6.9 billion from $1.9 billion, while net assets increased 35.9% to $14.3 billion.
Net assets in ether ETFs now stand about $2.1 billion above cumulative net inflows. Two weeks earlier, assets had trailed inflows by about $711 million.
Cumulative inflows remain positive, but the year is still negative
Since launch, cumulative net inflows have reached $53.7 billion for bitcoin funds and $12.2 billion for ether funds.
One strong week has not erased the year’s losses. Bitcoin ETFs remain down about $2.9 billion on a year-to-date basis, while ether ETFs are still down about $191.8 million. Even so, the combined year-to-date deficit has narrowed from $5.7 billion.
Those losses were built during a punishing stretch in which the funds turned year-to-date flows negative and posted the third-worst weekly outflow on record.
