U.S. spot Bitcoin ETFs recorded total net outflows of $148.69 million in a single day, ending a 10-trading-day streak of net inflows. Fidelity's FBTC led withdrawals with $125.58 million, followed by Bitwise's BITB at $13.63 million and BlackRock's IBIT at $9.48 million. The remaining products recorded no net inflows or outflows. Despite the daily reversal, cumulative net inflows for September totaled $2.65 billion, while year-to-date net inflows stood at $930.4 million. The $125.58 million figure was identified as FBTC's fund-level net outflow rather than a separately detailed client transaction.
