Bitcoin And Ethereum ETFs Surge As Markets Rebound

A dramatic reversal in U.S. crypto ETF flows sees Bitcoin and Ethereum funds post major inflows after a week of heavy outflows, with institutional demand and mainstream adoption both showing renewed strength.

After a turbulent week marked by dramatic swings in investor sentiment, U.S. cryptocurrency exchange-traded funds (ETFs) closed out September 18, 2026, with a broad-based resurgence in demand—most notably for Bitcoin and Ethereum products. According to Farside Investors and reporting from multiple financial news outlets, the day’s ETF inflows signaled renewed institutional interest, though questions remain about the durability of this apparent turnaround.

Bitcoin ETFs led the charge, raking in a staggering $433.03 million in net inflows on Friday. Fidelity’s FBTC was the standout, attracting $310.72 million, while BlackRock’s IBIT followed with $108.44 million. Bitwise’s BITB, VanEck’s HODL, and ARK & 21Shares’ ARKB also posted positive figures, albeit in smaller amounts. Remarkably, no listed Bitcoin ETF recorded an outflow during the session—a welcome change after the hefty withdrawals earlier in the week.
