US-listed spot Bitcoin exchange-traded funds recorded their strongest three-week inflow stretch of 2026, attracting $986.9 million in the week ending Friday. Net inflows over the past three weeks totaled $3.8 billion during a period when Bitcoin traded around $80,000.
According to SoSoValue data, total net assets across the funds stood at $101.3 billion on Friday, after briefly reaching $103.3 billion the previous day. Cumulative net inflows have reached $55.6 billion, though year-to-date net flows remain approximately $1 billion negative.
The recent inflows represent a significant shift from heavy outflows earlier in 2026, marking a sharp turnaround in investor demand for Bitcoin ETFs.
Daily Flows and Leading Funds
Friday's inflows moderated considerably, with US spot Bitcoin ETFs attracting $174.6 million in net inflows, down sharply from the nearly $731 million recorded Thursday. BlackRock's iShares Bitcoin Trust (IBIT), the largest spot Bitcoin ETF by assets, drew $117.4 million on Friday, accounting for approximately 67% of the day's total net inflows. Fidelity's Wise Origin Bitcoin Fund (FBTC) contributed $57.2 million, while all other US spot Bitcoin ETFs recorded no net flows for the day.
The slowdown coincided with Bitcoin's decline from around $81,200 to briefly below $79,000 on Friday, trading at $79,716 at publication time, still up approximately 2.6% over the prior seven days.
Diverging Trends in Altcoin ETFs
Bitcoin ETF inflows increased about 7% compared with the previous week, while inflows into US spot Ether and XRP ETFs declined significantly. Spot Ether ETF inflows dropped to $218.4 million from $824.4 million, representing a 74% decrease, while XRP ETF inflows fell to $19 million from $110.5 million, a decline of 83%.
Despite weaker recent inflows, both Ether and XRP ETFs remain in positive territory for the year, with US spot Ether ETFs having recorded approximately $863 million in net inflows year-to-date and XRP ETFs attracting roughly $515 million.
