Fidelity's FBTC Drives $433M Bitcoin ETF Rebound
Fidelity's Wise Origin Bitcoin Fund (FBTC) led a dramatic turnaround in U.S. spot Bitcoin exchange-traded funds (ETFs), posting a $433 million inflow on September 18, 2026, after midweek withdrawals and market volatility.
The sector narrowly avoided its second consecutive week of net outflows, with investors pouring $310.7 million into Fidelity's FBTC and smaller but still positive flows into other funds.
Despite the surge, the broader weekly picture remained mixed, with BlackRock's iShares Bitcoin Trust (IBIT) accumulating $120.6 million across five sessions, while the other Bitcoin funds lost approximately $194.4 million.
