Bitcoin ETFs See $433 Million Inflow as Fidelity’s FBTC Leads

Bitcoin ETFs — U.S. spot Bitcoin exchange-traded funds (ETFs) recorded a net inflow of $433 million on Friday, September 20, 2026, led by a significant contribution from Fidelity’s FBTC fund.

Fidelity’s FBTC accounted for $310.7 million of the total daily inflow, a substantial sum that helped push the products to a positive weekly performance. The inflows on Friday were crucial in offsetting earlier withdrawals seen earlier in the week.

In a contrasting move, U.S. spot Ethereum ETFs snapped a four-week streak of net inflows, according to the report. The shift highlights diverging investor sentiment between the two major crypto asset classes in the regulated fund space.

The data indicates continued institutional interest in Bitcoin through the ETF wrapper, with specific funds like Fidelity’s attracting the bulk of capital on high-volume days.
