Content overview: “BlackRock's IBIT Bitcoin ETF Rakes in $665M as Rivals Fidelity, Grayscale Lose Funds”. BlackRock's iShares Bitcoin Trust (IBIT) pulled in roughly $665.16 million in net inflows on Monday, October 19, according to fund-flow data from SoSoValue. The surge stood in stark contrast to the broader U.S. spot Bitcoin ETF market, which saw combined net inflows of only about $526.6 million. The gap highlights a clear investor preference for the largest Bitcoin fund, even as competing products faced redemptions.
Fidelity's FBTC lost about $83.6 million, while Grayscale's GBTC shed roughly $54.9 million, meaning IBIT's inflows more than offset those outflows. The one-day numbers suggest that institutional and retail investors are consolidating exposure into the most liquid and established ETF, rather than spreading demand across the entire category. The flows also follow a Friday session of net withdrawals, underscoring how quickly sentiment can shift amid market volatility.
