BlackRock and Fidelity have made waves in the ETF world with the debut of their spot Bitcoin exchange-traded funds (ETFs), achieving a remarkable milestone by amassing over $3 billion in assets within the first month of trading. This feat places them in an exclusive league, as only two ETFs out of more than 5,500 launched in the United States over the past three decades have reached this significant asset threshold so rapidly. The Bloomberg Intelligence data underscores the exceptional performance of BlackRock's IBIT and Fidelity's FBTC, both securing over $3 billion in assets within just 17 trading days, setting them apart as unparalleled leaders in the ETF landscape.
