U.S. spot Bitcoin ETFs recorded $2.386 billion in net inflows during the Sept. 21-25 trading week, marking a near one-year high and extending the products' recovery after a prolonged period of negative 2026 flows. BlackRock's IBIT led with $1.158 billion, lifting its cumulative historical inflows to $65.280 billion. Fidelity's FBTC attracted $702 million and reached $11.060 billion cumulatively, while WisdomTree's BTCW posted the largest weekly outflow at $4.016 million. Total net assets across the funds reached $108.420 billion, or 6.43% of Bitcoin's total market value, and cumulative historical net inflows stood at $57.550 billion. Earlier figures had placed the weekly inflow at about $2.39 billion and 2026 flows at roughly $925 million to $934 million positive, reflecting a discrepancy in reporting precision.
