Fidelity Leads $433 Million Inflow Into US Bitcoin ETFs

U.S. spot Bitcoin ETFs attracted $433.03 million in net inflows on September 18, 2026, recording their second consecutive trading day of positive flows.

Fidelity’s Wise Origin Bitcoin Fund, FBTC, led with $310.72 million, according to the September 18 fund-flow figures. BlackRock’s iShares Bitcoin Trust, IBIT, followed with $108.44 million. Those two funds accounted for most of the money entering the category during the session.

The $433.03 million represents net flows across U.S. spot Bitcoin ETFs rather than subscriptions to an individual product.

Ethereum investment products also attracted fresh capital. U.S. spot Ethereum ETFs recorded $144.8 million in net inflows on the same day, according to SoSoValue data, giving both cryptocurrency ETF categories a positive session.
