US spot Bitcoin ETFs recorded $2.65 billion in net inflows in September, their second-highest monthly total since October 2025, according to SoSoValue data.

The inflow was down from $3.52 billion in August but remained above levels seen through much of the past year. Spot Ether ETFs attracted $832.43 million in September, compared with $1.85 billion the previous month, marking their second-highest monthly inflow since August 2025.

Bitcoin ETFs added another $102.7 million on 1 October, while Ether ETFs recorded $55.4 million in outflows.

Zeus Research analyst Dominick John said the continued ETF inflows indicate institutional demand has remained strong and could point to a sustained market recovery.
