BlackRock's IBIT Swamps Fidelity's FBTC in Bitcoin Fund Flows

BlackRock's iShares Bitcoin Trust (NASDAQ: IBIT) recorded an astonishing $196 million in inflows on October 1, 2026, the largest single-day inflow for any U.S. spot Bitcoin fund that week.

In contrast, the Fidelity Wise Origin Bitcoin Fund (CBOE: FBTC) experienced a challenging day, facing $61 million in outflows and finishing the week with only one day of positive inflows.

The stark contrast highlights IBIT vs. FBTC performance, especially since both funds invest in the same cryptocurrency and charge an identical annual fee of 0.25%.

Over the four days from September 28 to October 1, the 12 U.S. spot Bitcoin funds collectively took in around $51 million, according to SoSoValue.
