Bitcoin ETF inflows just notched their second-best month in nearly a year, and the numbers suggest Wall Street’s appetite for crypto exposure hasn’t cooled off as much as some traders feared. US spot bitcoin exchange-traded funds pulled in $2.65 billion in net inflows during September, according to data from SoSoValue cited by The Block. That figure places last month just behind August as the strongest stretch for bitcoin ETFs since October 2025, and it’s giving analysts fresh reason to talk about sustained institutional demand heading into the final quarter of the year.
Key takeaways
US spot bitcoin ETFs saw net inflows of $2.65 billion during September, marking their second-biggest monthly total since October 2025.
September’s total came in below August’s $3.52 billion but stayed well above most of the past year’s monthly averages.
Spot ether ETFs drew $832.43 million in September, their second-best month since August 2025.
On October 1, bitcoin ETFs gained $102.7 million while ether ETFs lost $55.4 million to net outflows.
The Crypto Fear & Greed Index sat at 69, in “greed” territory but not extreme, as bitcoin traded at $86,626.
US Bitcoin ETF Inflows Hit $2.65 Billion in September
Bitcoin ETF inflows totaled $2.65 billion in September, marking the second-strongest month for the funds since October 2025. That’s the headline number, and it confirms that institutional buyers kept adding exposure even as crypto prices wobbled through parts of the summer and early fall.
September Inflows Compare to August’s $3.52 Billion
The September figure did fall short of August, when bitcoin ETFs drew $3.52 billion. Still, the gap isn’t a red flag on its own. September’s total remained comfortably above the levels these funds posted through most of the past twelve months, which points to a demand floor that hasn’t really cracked. SoSoValue’s tracking of the US spot bitcoin ETF market has become one of the clearest windows into how traditional finance is treating bitcoin as an asset class, and the September numbers suggest that window is still showing steady buying rather than a retreat.
Ether ETFs Also Post Strong September Inflows but Early October Shows Outflows
Spot ether ETFs had their own solid month, drawing $832.43 million in net inflows in September — the second-largest monthly total for those products since August 2025. That’s a notable showing for ether funds, even though it fell well short of August’s $1.85 billion. The pattern here mirrors bitcoin’s: a strong month that didn’t quite match the prior one, but still outperformed the broader trend from earlier in the year.
Bitcoin Gains, Ether Slips on October 1
The first trading day of October split the two markets apart. Bitcoin ETFs added $102.7 million in net inflows, while ether ETFs saw $55.4 million flow back out. It’s a reminder that even when the broader monthly trend looks encouraging, day-to-day flows can diverge sharply between the two largest crypto ETF categories.
Why Analysts See Sustained Institutional Demand
According to Dominick John, an analyst at Zeus Research, the ETF inflow figures indicate that institutional demand “has not faded,” suggesting a more lasting recovery rather than a brief uptick, as he told The Block. His read on the numbers frames September’s bitcoin ETF inflows as evidence that large investors are still treating dips as buying opportunities rather than exits.
Fear & Greed Index Signals Greed, Not Euphoria
John also pointed to broader sentiment data to back up his view. “With the Q4 bottom seemingly established, continued ETF inflows also signal improving market sentiment and a potentially more bullish setup heading into the final quarter,” he said. The Crypto Fear & Greed Index stood at 69 at the time, placing the market in “greed” territory. John said that level suggests “sentiment has strengthened without reaching extreme levels” — in other words, investors are optimistic, but the market hasn’t tipped into the kind of euphoria that often precedes a sharp pullback.
This distinction matters for anyone trying to read the tape right now. A Fear & Greed reading near 70 without hitting the high 80s or 90s typically means there’s still room for buyers to keep adding before sentiment becomes stretched. For an asset class that moves on narrative as much as fundamentals, that gap between “greed” and “extreme greed” is often where institutional capital keeps flowing rather than pulling back.
What Traders Are Watching Next
Traders are now turning their attention to a cluster of US economic data that could shape rate expectations and, by extension, risk appetite for crypto. John flagged the upcoming jobless claims report, inflation figures, and commentary from Federal Reserve officials as the next set of catalysts likely to move both ETF flows and token prices.
Jobless Claims, Inflation Data and Fed Commentary Loom
“The Oct. 8 jobless claims report will offer another read on the U.S. labor market, while inflation data and Fed commentary could shift rate expectations,” John said. The jobless claims report is scheduled for Thursday, October 8, and traders will be pairing that release with incoming inflation data to gauge how much room the Fed has to adjust policy. Any surprise on either front could ripple through bitcoin ETF inflows and ether ETF flows alike, given how closely institutional positioning tends to track rate expectations.
At the same time, price trends have remained positive, with bitcoin rising 3.1% in the last 24 hours to reach $86,626 by 1 a.m. ET Friday, as reported on The Block’s price page, and ether gaining 1% over the same period to trade at $2,735. Those gains, combined with the October 1 bitcoin ETF inflow, suggest the market entered the new quarter with at least some of the momentum that built through September.
