U.S. spot Bitcoin (BTC) ETFs pulled in $2.39 billion last week, recording the strongest weekly net inflow since October 2025. Despite a late-week pullback in Bitcoin prices, new capital inflows are spreading across virtual asset funds overall.
Key takeaways
U.S. spot Bitcoin ETFs saw inflows of $2.39 billion last week, recording the largest weekly net inflow since October 2025 and surpassing the August 2026 peak as well.
Cumulative net outflows, which had reached roughly $5.55 billion from the start of this year through early July, have since rebounded to a net inflow of about $0.92 billion.
Other U.S. spot crypto ETFs also showed steady inflows over the same period.
Bitcoin ETFs see a sudden reversal in 2026
According to SoSoValue, U.S. spot Bitcoin exchange-traded funds added another $134.5 million on just Friday, bringing the total net inflow for the entire week to $239 million. This is the highest level since the week ended October 10, 2025, when $2.71 billion flowed in, and it also surpassed the previous intra-year peak of $1.92 billion recorded in August 2026.
With this inflow rally, the cumulative net fund flow into Bitcoin ETFs since the start of the year reversed to about $922.6 million net inflow as of last Friday. This stands in stark contrast to the big negative of roughly a $5.55 billion net outflow on a cumulative basis as recently as early July.
However, flows during the week gradually slowed. Early Monday saw inflows close to $1 billion, showing a strong start, but the pace then slowed after midweek. During the same period, the price of Bitcoin briefly rose above $87,100, but at the time of writing it had fallen to about $83,116. According to CoinGecko, it was down 1.6% over 24 hours, though still up 1.7% on a seven-day basis.
Even with the price correction, investor sentiment remained resilient. The crypto “Fear & Greed Index,” compiled by Alternative.me, rose from 70 to 74 over the past week, and still stayed in the “Greed” range.

Funds also flow into Ether and XRP ETFs
About $690 million in net inflows entered U.S. spot Ether (ETH) ETFs over the same period. It quickly reversed the prior week’s net outflow of roughly $140 million, flipping demand and supply. Spot XRP (XRP) ETFs also pulled in about $76 million, showing that new demand via ETFs was not limited to Bitcoin alone.
Bloomberg Intelligence ETF analyst **Eric Balchunas** linked the recent recovery in Bitcoin ETF inflows to an expanded long-term Treasury buyback plan by the U.S. Department of the Treasury. He interprets this flow not as something limited to Bitcoin as an individual asset, but as part of a broader shift toward improving liquidity and risk appetite across the market.
This viewpoint also reminds us that ETF fund flows reflect not just demand for a particular asset, but also the macro environment and liquidity conditions. In fact, last week’s data shows that funds were flowing simultaneously into multiple U.S. spot crypto ETF products.
In 2026, Bitcoin ETF fund flows went through sharp fluctuations. As of the start of the year, by early July they were at roughly a $5.55 billion net outflow on a year-to-date basis; now they have swung back to about a $922.6 million net inflow. The “big week” worth $2.39 billion recorded in September is seen as a trend-changing event that significantly outpaced August’s peak of $1.92 billion.
