Spot Bitcoin ETFs Extend September Recovery
SoSoValue data showed that September inflows stayed well above levels seen through much of the past year. The monthly total also came as Bitcoin recovered during the quarter, while investors continued tracking daily fund flows for signs of steady demand.
Earlier data showed a five-session buying streak that brought about $2.34 billion into U.S. Bitcoin funds through September 23. The run included several strong sessions before daily inflows slowed, showing how quickly fund activity can shift from day to day.
Ether Funds Also Record Strong Month
Spot ether ETFs added $832.43 million during September, down from $1.85 billion in August. Even with the decline, September ranked as their second-largest monthly inflow since August 2025, showing continued demand for regulated ether products.
Recent market data also showed Ethereum ETF demand strengthening during the final week of September. U.S. spot ether ETFs drew nearly $690 million in the week ended September 25, while large holders increased their ether balances during the same period.
October Starts With Mixed ETF Flows
The first trading day of October produced different results across the two largest crypto ETF markets. Spot Bitcoin ETFs added $102.7 million, while spot ether ETFs recorded $55.4 million in net outflows.
Bitcoin also moved higher. The asset gained 3.1% over 24 hours to $86,626 early Friday, while ether rose 1% to $2,735. The Crypto Fear and Greed Index reached 69, placing market sentiment in greed territory without reaching its highest range.
Economic Data Remains in Focus
Analyst Dominick John said continued ETF buying showed that institutional demand had not faded. Bitcoin’s latest price move also followed a period of strong ETF activity, although traders continued watching bond yields, inflation data, and Federal Reserve signals.
Market attention now turns to upcoming labor data, including the October 8 jobless claims report. Investors will also monitor inflation releases and Federal Reserve comments, while Spot Bitcoin ETFs remain a key measure of regulated demand entering the final quarter.
