U.S. spot bitcoin ETFs just logged their quietest full trading week since October 2024, with volume down 14% to roughly $8.05 billion. The funds scraped together only $33.8 million in net inflows, while spot ether ETFs pulled in more than three times that — outdrawing their larger rivals for a second straight week.
Trading in U.S. spot bitcoin ETFs has slowed. Weekly volume slid to its lowest level for a full five-session week since the week ending Oct. 11, 2024. At roughly $8.05 billion, that marked a 14% drop from $9.37 billion the week before, with bitcoin holding near $64,000.
Despite the lull, the funds closed with about $33.8 million in net inflows, a third straight positive week after they ended a record eight-week outflow streak earlier this month. That was the weakest of the three, trailing $75.7 million the previous week and $197.4 million before that.
The week's shape told the story. Bitcoin ETFs drew about $499.1 million over the first three sessions. Investors then pulled $225.2 million on Thursday and another $240.1 million on Friday, erasing nearly all the earlier gains.
BlackRock's iShares fund leads the week's outflows
BlackRock's iShares Bitcoin Trust, the largest spot bitcoin fund by net assets, recorded roughly $95.5 million in net outflows after shedding a combined $414.7 million over the final two sessions. Grayscale's Bitcoin Mini Trust and the ARK 21Shares Bitcoin ETF softened the blow with approximately $85.8 million and $78.1 million in inflows, respectively.
Ether funds keep pulling ahead
Spot ether ETFs told a different story. They drew approximately $103.9 million in net inflows, a third consecutive positive week and more than triple the bitcoin total. Over the past three weeks the ether products have gathered about $293.8 million, nearly matching the $306.9 million that flowed into bitcoin ETFs.
Fund size puts those inflows in context. Ethereum ETF net assets stood at $10.17 billion on Friday, against $77.82 billion for the bitcoin products, so the latest ether inflows equaled roughly 1% of assets versus about 0.04% for bitcoin.
Both groups still sit underwater for the year. Bitcoin ETFs remain at about $5.23 billion in net outflows since the start of 2026, while ether ETFs are down roughly $1.15 billion. Yet ether has led in July, drawing about $337.7 million against $234 million for the bitcoin funds.
