BlackRock’s iShares Bitcoin Trust (IBIT) has set a new benchmark in the U.S. spot Bitcoin ETF landscape by amassing $91.06 billion in assets under management as of August 13, 2025.
This milestone comes amid strong investor interest, even as the price of bitcoin experienced recent volatility.
IBIT extends its market lead
IBIT has captured 3.72% of the total bitcoin supply and continues to draw both institutional and retail investors.
Since its January 2024 debut, IBIT has attracted over $5 billion in net inflows during its first month, a record for new U.S. ETFs.
By mid-July 2025, IBIT crossed $80 billion in cumulative net inflows, highlighting its unmatched investor appeal.

Competitors
Competitors like Fidelity’s FBTC and Grayscale’s GBTC trail behind, managing $24.77 billion and $22.18 billion, respectively.
Grayscale’s GBTC has seen $23.72 billion in cumulative outflows since converting to an ETF, while Ark Invest’s ARKB and Bitwise’s BITB remain smaller players.
Inflation data spurs bitcoin selloff
Bitcoin’s price briefly surged to $124,000 on optimism that the Federal Reserve would cut rates.
However, hotter-than-expected U.S. inflation data prompted a sharp reversal, sending bitcoin below $118,000 and triggering more than $1 billion in liquidations across digital asset markets.
Overall, more than $930 million in leveraged bitcoin positions were wiped out in less than a day.
