US-listed spot Bitcoin exchange-traded funds posted their strongest three-week inflow streak of 2026, with Bitcoin holding near the $80,000 level. The recent surge has reversed trends seen earlier this year, when heavy outflows weighed on the market.
Record inflows fuel Bitcoin ETF growth
From Monday to Friday last week, spot Bitcoin ETFs in the US attracted $986.9 million, according to data compiled by SoSoValue. Over the past three weeks, net inflows reached a total of $3.8 billion, marking the most significant inflow period so far this year.
Total net assets across these US spot Bitcoin ETFs stood at $101.3 billion at the end of the week, having briefly peaked at $103.3 billion the day before. Cumulative net inflows now sit at $55.6 billion, reflecting strong investor participation despite previous volatility in 2026.
However, year-to-date flows remain approximately $1 billion negative, underscoring the challenging start to 2026 before this recent turnaround.
Friday saw net inflows of $174.6 million into US spot Bitcoin ETFs, a notable decrease from the previous day’s figure of nearly $731 million. Analysts attributed the slowdown to profit-taking and softer market sentiment as Bitcoin’s price moved lower late in the week.
BlackRock’s iShares Bitcoin Trust (IBIT), now the largest US spot Bitcoin ETF by assets, recorded $117.4 million in inflows on Friday, representing 67% of all new money entering US spot Bitcoin ETFs that day. Fidelity’s Wise Origin Bitcoin Fund (FBTC) followed, attracting $57.2 million and standing as the only other spot Bitcoin ETF in the US to see net inflows for the day. All other US spot Bitcoin ETFs experienced neutral flows.
Bitcoin’s price declined from roughly $81,200 to briefly under $79,000 on Friday, and BTC traded at $79,716 at the end of the period, still up about 2.6% over the previous seven days, CoinGecko data showed.
Bitcoin ETF gains contrast with declining Ether and XRP flows
Spot Bitcoin ETF inflows grew about 7% compared to the prior week, highlighting robust interest even as altcoin-focused ETFs lost momentum.
US spot Ether ETF inflows dropped by roughly 74%, totaling $218.4 million, down sharply from $824.4 million the prior week. Meanwhile, US XRP ETF inflows fell 83% to $19 million, compared to $110.5 million a week earlier.
Despite reduced weekly inflows, both Ether and XRP ETFs remain in positive territory for the year, with net inflows of about $863 million and $515 million, respectively, according to SoSoValue.
These variations in ETF demand reflect a shifting market environment, where altcoins have seen less attention as Bitcoin continues drawing sizable allocations.
