U.S. spot bitcoin ETFs recorded $2.65 billion in net inflows during September, their second-largest monthly haul since October 2025, according to SoSoValue data. The total came in below August's $3.52 billion but stayed well above the trailing-year baseline, and the first day of October added another $102.7 million to the streak.
Dominick John, analyst at Zeus Research, told The Block that the consistency of the flows signals institutional demand "has not faded." Spot ether ETFs drew $832.43 million in September, their second-largest monthly inflow since the product launched.
Why it matters
Two consecutive months above $2.5 billion in net inflows is the kind of cadence that points to structural rather than reactive demand. John's read is that the Q4 bottom has been established, and continued ETF inflows confirm improving sentiment heading into the final quarter of the year.
The ether ETF total, while down from August's $1.85 billion, still ranks as the second-largest monthly inflow on record. Bitcoin and ether products moving in tandem is itself a signal that the institutional allocation thesis is broadening beyond BTC alone.
Market impact
BTC climbed 3.1% over 24 hours to $86,626 as of 1:00 a.m. ET Friday, while ETH rose 1% to $2,735. The Crypto Fear & Greed Index sat at 69, in greed territory but below the extreme readings that have historically preceded corrections.
Traders will watch the Oct. 8 jobless claims report, plus upcoming inflation data and Federal Reserve commentary, for the next macro impulse. As long as the ETF tape keeps printing net positive, the institutional bid remains the dominant force framing the market.
