US spot Bitcoin ETFs have clawed back billions in recent weeks, but they’re still about $1 billion underwater for 2026. That’s the gap between what investors have pulled out and what they’ve put back in since January.
The summer that almost broke the streak
June 2026 was the villain in this story. Net redemptions from US spot Bitcoin ETFs hit roughly $4.5 billion that month alone. May wasn’t exactly a picnic either, with heavy outflows contributing to the cumulative damage.
August’s $3.5 billion comeback
Net inflows of $3.52 billion poured into spot Bitcoin ETFs during August, making it the strongest monthly performance of 2026 by a wide margin.
The momentum carried into September. A three-week inflow streak running through early September delivered approximately $3.8 billion in fresh capital. The week ending September 5 alone accounted for $986.9 million in net inflows, pushing the year-to-date deficit down to roughly $1 billion.
One particularly aggressive day stood out: September 3 saw $730.9 million flow into Bitcoin ETFs in a single session.
The bigger picture: $55.6 billion and counting
The cumulative scorecard for US spot Bitcoin ETFs since their January 11, 2024 launch shows total net inflows of approximately $55.6 billion, supporting aggregate assets under management of roughly $101.3 billion.
BlackRock’s iShares Bitcoin Trust (IBIT) continues to anchor the category as the largest single fund, with Fidelity’s Wise Origin Bitcoin Fund (FBTC) also playing a pivotal role in driving the recovery phase. The competitive landscape includes offerings from ARK 21Shares, Bitwise, and others, while legacy products such as Grayscale’s GBTC continue to experience redemptions.
