U.S. spot bitcoin and ether ETFs pulled in $2.6 billion last week. That is their strongest week since October 2025. Weekly trading volume more than tripled to $29 billion as both assets rallied sharply.
The inflows, according to The Block’s analysis of SoSoValue data, reversed a combined $392.0 million outflow from the prior week. A swing of roughly $3 billion in seven days. They more than doubled the $1.1 billion combined inflow recorded the week before that, which had stood as the strongest result for both categories since April.
Spot bitcoin ETFs drove most of the action. They logged $1.9 billion in net inflows. Spot ether ETFs drew $697.2 million. Both categories posted their largest weekly inflows of 2026.
Trading volume jumped across the board. Bitcoin ETF volume climbed to $22.1 billion from $6.9 billion the prior week, an increase of more than 219%. Ether ETF volume rose to $6.9 billion from $1.9 billion, up 259.4%. Combined volume reached roughly $29 billion.
Buyers concentrated midweek. Funds drew $517.2 million on Wednesday, their largest daily inflow since May 4. Thursday brought $606.3 million more, led by $503.0 million into BlackRock’s IBIT.
Bitcoin traded near $77,200 on Saturday afternoon. It had briefly crossed $79,000 on Friday during its largest weekly gain in two years. Ether changed hands around $2,423. Both assets gained between 24% and 28% for the week.
The price move lifted assets under management across both categories. Bitcoin ETF net assets climbed 25.4% to $96.1 billion from $76.6 billion. Ether ETF assets rose 35.9% to $14.3 billion from $10.5 billion. Each figure reflects both new inflows and price appreciation in the underlying assets.
For ether ETFs, the weekly inflow was the largest since the week ending Oct. 3, 2025, when they attracted nearly $1.3 billion. The category had recorded a $2.3 million net outflow the week before last. Ether ETF net assets now exceed cumulative net inflows by about $2.1 billion. Two weeks earlier, assets sat roughly $711 million below cumulative inflows. The reversal was driven by ether’s price gains alongside fresh buying.
For bitcoin ETFs, the $1.9 billion week was the largest since the week ending Oct. 10, 2025, which saw $2.7 billion in net inflows. Cumulative net inflows since the funds began trading now stand at $53.7 billion.
The strong week did not erase the year’s damage. Bitcoin ETFs have seen roughly $2.9 billion in net outflows for 2026. Ether ETFs are down about $191.8 million. The latest week did reduce the two categories’ combined year-to-date deficit from $5.7 billion to $3.1 billion.
The Block did not name a driver for the rally beyond the price move itself, and no fund issuer was quoted in the article.
