BlackRock's Bitcoin Fund Draws Record Inflows Exceeding Half Billion Dollars

BlackRock's iShares Bitcoin Trust experienced a massive influx of capital on September 4, 2026, pulling in $117.4 million as clients continued to invest in the largest spot Bitcoin ETF.

This single-day haul pushed total U.S. spot Bitcoin ETF inflows to $174.6 million that day, with Fidelity's FBTC contributing the remaining $57.2 million.

The massive influx is not an isolated incident; cumulative net inflows into IBIT have now exceeded $60 billion since its launch in January 2024, cementing its position as the dominant vehicle in the U.S. spot Bitcoin ETF category by a considerable margin.
