U.S. spot bitcoin and ether ETFs drew a combined $2.6 billion in net inflows last week, their strongest week since October 2025. Bitcoin ETFs accounted for $1.9 billion and ether ETFs $697.2 million, giving both categories their largest weekly inflows of 2026. The result reversed the previous week's combined $392.0 million outflow and created a roughly $3 billion week-over-week swing.
Why it matters
The flow reversal puts institutional ETF demand back at the center of the crypto rally. Bitcoin ETF cumulative net inflows since launch reached $53.7 billion, while cumulative ether ETF inflows reached $12.2 billion. The latest combined inflow also more than doubled the $1.1 billion recorded for the week ending Aug. 7.
Buying intensified during the rally. Bitcoin funds drew $517.2 million on Wednesday and $606.3 million on Thursday, including $503.0 million into BlackRock's IBIT. That timing links the strongest demand to the market rally.
Market impact
Bitcoin ETF trading volume rose to $22.1 billion from $6.9 billion, an increase of more than 219%. Ether ETF volume climbed to $6.9 billion from $1.9 billion, up 259.4%. Net assets rose 25.4% for bitcoin funds to $96.1 billion and 35.9% for ether funds to $14.3 billion, reflecting both fresh inflows and price gains.
Bitcoin briefly traded above $79,000 during its largest weekly gain in two years, while BTC and ETH each gained between 24% and 28%. The latest inflows narrowed the combined 2026 ETF deficit from $5.7 billion to $3.1 billion, but did not erase it. Bitcoin ETFs still show about $2.9 billion in 2026 net outflows and ether ETFs about $191.8 million.
