BlackRock’s IBIT extends dominance in ETFs
IBIT’s dominance was not confined to derivatives. At press time, it accounted for more than 50% of the U.S. spot Bitcoin ETF market, representing 3.84% of the circulating Bitcoin supply.
Bloomberg analyst Eric Balchunas called the scale unprecedented, noting
“An equity ETF would need $2.2 trillion in assets to have as much ownership of its underlying asset class. For perspective, SPY owns 1.1% of most stocks and it’s 32 years old — IBIT is still a toddler.”
In the past 24 hours, U.S. Spot Bitcoin ETFs recorded $429.96 million in inflows, with IBIT contributing $199.43 million. That reinforced its role as the leading driver of institutional demand.
