US Spot Bitcoin ETFs Log $527M Inflow as BlackRock Dominates Market Rebound

U.S. spot Bitcoin ETFs secured up to $526.7 million in net inflows on Oct. 19, marking their largest single-day haul since Sept. 22. The turnaround was driven solely by BlackRock's iShares Bitcoin Trust (IBIT), which captured $665.2 million in new capital, its largest single-day inflow in a year. This concentrated demand offset substantial redemptions across rival products, including $83.6 million in outflows from Fidelity's FBTC and $54.9 million from Grayscale's GBTC. Despite the heavy ETF accumulation, Bitcoin traded around $81,564 to $82,060, while spot Ether ETFs shed $103.3 million.
