Bitcoin, ether ETFs draw $2.6B in strongest week since October

US spot bitcoin and ether ETFs drew a combined $2.6 billion in net inflows last week, their strongest week since October 2025, The Block reported, citing SoSoValue data. Bitcoin ETFs pulled in $1.9 billion and ether ETFs added $697.2 million, both categories posting their largest weekly inflows of 2026.

The result reversed a combined $392.0 million outflow the previous week, a swing of about $3 billion in a single week. It also more than doubled the $1.1 billion combined inflow recorded during the week ending August 7, which had itself been the strongest result since April.

The $1.9 billion flowing into bitcoin ETFs marked their largest weekly total since the week ending October 10, 2025, when they drew $2.7 billion. Cumulative net inflows since the funds began trading reached $53.7 billion. Weekly trading volume climbed to $22.1 billion from $6.9 billion, an increase of more than 219%, while combined net assets under management rose 25.4% to $96.1 billion from $76.6 billion, reflecting both the fresh inflows and bitcoin's price appreciation over the week.

• Bitcoin ETF inflows: $1.9 billion, largest since the week ending Oct. 10, 2025
• Ether ETF inflows: $697.2 million, largest since the week ending Oct. 3, 2025
• Bitcoin ETF volume: $22.1 billion, up more than 219% week over week
• Ether ETF net assets: $14.3 billion, up 35.9% from $10.5 billion
• Wednesday's inflow: $517.2 million, the largest daily total since May 4

Most of the buying landed during Wednesday and Thursday's rally. The funds drew $517.2 million on Wednesday, their largest daily inflow since May 4, then added $606.3 million on Thursday, led by $503.0 million entering BlackRock's IBIT alone.

Ether ETFs told a similar story. Their $697.2 million weekly total was the largest since the week ending October 3, 2025, when the funds attracted nearly $1.3 billion, and it followed a $2.3 million net outflow the week before last. Cumulative net inflows since launch now stand at $12.2 billion. Weekly trading volume rose to $6.9 billion from $1.9 billion, up 259.4%, and net assets climbed 35.9% to $14.3 billion from $10.5 billion. Ether ETF net assets now exceed cumulative net inflows by roughly $2.1 billion, a reversal from two weeks earlier when assets sat about $711 million below cumulative inflows, driven largely by ether's price gains alongside the fresh money.

The ETF inflows landed alongside a broad crypto rally. Bitcoin briefly traded above $79,000 on Friday during its largest weekly gain in two years, and both bitcoin and ether gained between 24% and 28% for the week. Bitcoin traded near $77,200 Saturday afternoon, with ether around $2,423, a move that also lifted institutional treasuries: Strategy's Bitcoin holdings returned to profit during the same stretch.

The strong week didn't fully erase 2026's losses across the two fund categories. Bitcoin ETFs have still seen about $2.9 billion in net outflows for the year, and ether ETFs remain down roughly $191.8 million. The latest weekly inflows narrowed the two categories' combined year-to-date deficit from $5.7 billion down to $3.1 billion.
