U.S. spot bitcoin ETFs draw second-largest monthly inflow since October 2025
Bitcoin ETFs see strong inflows

Institutional appetite for crypto exchange-traded funds remains firm entering the final quarter, with U.S. spot bitcoin products attracting $2.65 billion in net inflows in September. The total is lower than August's $3.52 billion but still stands well above most monthly levels seen over the past year.

Highlights

  • U.S. spot bitcoin ETFs posted $2.65 billion in net inflows for September, their second-largest monthly intake since October 2025, after $3.52 billion in August.
  • Spot ether ETFs saw $832.43 million in September inflows, their second-largest since August 2025, versus $1.85 billion taken in during August.
  • The Crypto Fear & Greed Index sits at 69, signaling strengthened but not extreme sentiment as institutional participation in spot ETFs remains robust.

September ETF flows and early October trading

As reported by The Block, citing SoSoValue data, U.S. spot bitcoin ETFs post $2.65 billion in net inflows in September, marking their second-largest monthly intake since October 2025. That compares with $3.52 billion in August, while spot ether ETFs bring in $832.43 million in September after drawing $1.85 billion a month earlier.

The September figure for spot ether ETFs is also their second-largest monthly inflow since August 2025. On the first day of October, bitcoin ETFs add another $102.7 million, while ether ETFs record $55.4 million in net outflows.

Institutional demand and market sentiment

Dominick John, an analyst at Zeus Research, says the ETF flows indicate institutional demand has not faded and point to a more sustained recovery in crypto markets. He says a fourth-quarter bottom appears to be in place, and continued inflows signal improving sentiment and a potentially more bullish setup for the rest of the quarter.

John also says traders are watching ETF activity alongside key U.S. economic releases. He points to the Oct. 8 jobless claims report as another test of the U.S. labor market, while inflation data and commentary from the Federal Reserve could alter interest-rate expectations.

The Crypto Fear & Greed Index stands at 69, in greed territory, which John says suggests sentiment has strengthened without moving into extreme levels. For digital-asset markets, continued allocations into spot ETFs remain a key gauge of whether institutional participation is holding up.

Our earlier report on Bitcoin’s chart signals highlighted that the August rebound began to look more durable after several failed bullish setups in late 2025 and early 2026. It noted improving long-term trend support and strengthening momentum, suggesting the move could underpin a broader recovery across the cryptocurrency market.
