Spot Bitcoin ETFs See $2.65 Billion Inflows in September, Second-Highest Since October 2025
U.S. spot bitcoin ETFs draw $2.65 billion in September
U.S. spot bitcoin exchange-traded funds (ETFs) attracted $2.65 billion in net investments during September, marking the second-largest monthly inflow since October 2025. ETFs are funds that trade on stock exchanges and track the price of an underlying asset like bitcoin.
The inflows were down from August’s $3.52 billion but remained well above levels seen throughout the past year. Spot ether ETFs also drew $832.43 million in September, compared with $1.85 billion in August. September’s ether total was their second-largest monthly inflow since August 2025.
Early October flows show mixed momentum
Bitcoin ETF inflows continued into the first day of October, reporting $102.7 million in net additions. Ether ETFs, however, shed $55.4 million on the same day.
Analyst says institutional demand remains intact
Dominick John, analyst at Zeus Research, said the ETF inflows suggest institutional demand “has not faded,” pointing to a more sustained recovery. With the fourth-quarter bottom seemingly established, continued ETF inflows also signal improving market sentiment and a potentially more bullish setup heading into the final quarter, he said.
Prices and sentiment data
Bitcoin climbed 3.1% over the past 24 hours to $86,626 as of 1:00 a.m. ET Friday, while ether rose 1% to $2,735. The Crypto Fear & Greed Index stood at 69 in “greed” territory, suggesting sentiment has strengthened without reaching extreme levels.
What traders will watch next
John said traders will continue to monitor ETF inflows for signs of sustained institutional demand, alongside key U.S. economic data. The Oct. 8 jobless claims report will offer another read on the U.S. labor market, while inflation data and Federal Reserve commentary could shift interest-rate expectations.
