US spot Bitcoin exchange-traded funds recorded about $2.65 billion in net inflows during September, their second-largest monthly inflow since October 2025 and their strongest monthly inflow of 2026 after August’s $3.52 billion. The total followed a Sept. 30 reversal, when the funds posted $148.7 million in net outflows after nine consecutive positive sessions that had attracted about $3.08 billion, according to Farside Investors. Fidelity’s FBTC accounted for $125.6 million of the withdrawals, while Bitwise’s BITB lost $13.6 million and BlackRock’s IBIT shed $9.5 million; the other nine listed funds reported no net flows. Spot ether ETFs attracted $832.43 million in September, down from $1.85 billion in August. Bitcoin traded near $83,800 early Oct. 1 as investors monitored whether ETF inflows would resume.
