BlackRock’s iShares Bitcoin Trust (IBIT) has crossed the $50 billion threshold in assets under management, cementing its position as the fastest-growing ETF product in history. The milestone was reached on April 4 as continued institutional inflows pushed the fund’s AUM past the landmark figure.
IBIT, which launched in January 2024, reached $10 billion faster than any ETF in history — in just 49 days. The fund has since become one of the 15 largest ETFs in the United States across all asset classes.
“This is a genuinely historic inflection point for Bitcoin as an institutional asset class,” said Robert Mitchnick, BlackRock’s head of digital assets. “The demand we’re seeing speaks for itself — this is long-term strategic allocation.”
Pension funds, endowments, and sovereign wealth funds now collectively represent approximately 22% of IBIT’s investor base. The combined AUM of all US spot Bitcoin ETFs now exceeds $110 billion. Analysts at Bernstein believe the market could reach $500 billion within three years.
