US Bitcoin ETFs pull in $987M in a week as three-week streak hits $3.8B

US spot Bitcoin ETFs attracted $986.9 million in net inflows for the week ending September 5, capping off a three-week streak that has funneled $3.8 billion into these products. Early 2026 was rough for Bitcoin ETF flows, with year-to-date net figures still sitting at approximately negative $1 billion. Three consecutive weeks of heavy buying haven't erased that deficit, but they've dramatically narrowed it.

Daily inflows during the week were anything but evenly distributed. Thursday alone accounted for roughly $731 million in net new capital, the largest single-day haul since January 14. Friday cooled off to $174.6 million. BlackRock's iShares Bitcoin Trust (IBIT) was responsible for $117.4 million of that total, while Fidelity's Wise Origin Bitcoin Fund (FBTC) contributed $57.2 million.

Total assets under management across all US spot Bitcoin ETFs stood at $101.3 billion as of the latest data, after briefly touching $103.3 billion during the week. Since their collective launch in January 2024, these funds have accumulated $55.6 billion in cumulative net inflows.

Bitcoin's price during the week hovered near $80K, dipping briefly below $79K before recovering to roughly $79,700. Spot Ether ETF inflows dropped 74% week-over-week, while XRP ETF products saw an 83% decline.
