Bitcoin ETF (IBIT.US) net inflow of $2.65 billion in September, institutional demand supports market recovery

According to Woofun AI, Zeus Research analyst Dominick John pointed out to The Block that institutional demand for crypto asset allocation has not weakened. This judgment is based on the strong recovery trend shown by ETF capital flows in September.

From a historical perspective, the US Bitcoin Spot ETF (IBIT.US) recorded a net inflow of $2.65 billion in September, which was lower than the $3.52 billion in August, but far above the average for the previous year, and was established as the second-highest monthly net inflow since October 2025. The Ethereum Spot ETF (ETHA.US) performed similarly well, with a net inflow of $8324.3 million in September, which was less than the $1.85 billion in August, the second-highest monthly net inflow since August 2025.

Data compiled by Woofun AI showed that as of October 1, Bitcoin ETFs continued to absorb $102.7 million, while Ethereum ETFs had a net outflow of $55.4 million.

Capital inflows directly boosted asset prices. As of 1 a.m. EST on Friday, BTC was up 3.1% to $86,626 and ETH was up 1% to $2,735 in 24 hours. The Crypto Fear & Greed Index recorded 69, which is in the greed range, confirming that market sentiment is growing but not extreme. John believes that, given the fourth-quarter low, continued net ETF inflows indicate that the trend in the coming quarter may be more optimistic.

The focus of the market is shifting to the reshaping of interest rate expectations from macro variables. The unemployment claim data released on October 8 will reveal the actual state of the US labor market, while inflation data and the Federal Reserve's statement will be key variables. Traders will closely monitor these indicators to verify the continuity of institutional demand and anticipate the potential impact of interest rate trends on the crypto market.
