BlackRock’s IBIT Surpasses $80 Billion in Assets, Setting New ETF Speed Record
BlackRock’s iShares Bitcoin Trust (IBIT) surpassed $80 billion in assets under management on July 10, becoming the fastest exchange-traded fund (ETF) to reach this milestone in 374 trading days.
Performance data shows IBIT’s trajectory surpassing that of its peers well before its first anniversary. As of late July 11, with assets reaching $83 billion, IBIT ranks as the 21st-largest ETF in the United States.

Inflows surge alongside the milestone
US spot Bitcoin ETFs attracted $1.18 billion on July 10, marking the third-largest daily haul recorded for these products, according to CoinShares head of research James Butterfill.
Data from Farside Investors indicated that IBIT led with $448.5 million in inflows, followed by Fidelity’s FBTC at $324.3 million and Ark 21Shares’ ARKB at $268.7 million.
Furthermore, Farside data shows cumulative net inflows of $51.3 billion across the 12 US spot Bitcoin ETFs through July 11.
IBIT accounts for $53.45 billion of that total, followed by FBTC with $12.62 billion, Ark 21Shares’ ARKB with $3.02 billion, and Bitwise’s BITB with $2.29 billion.
GBTC’s $23.38 billion in redemptions offsets a significant portion of industry inflows, yet the group’s net figure remains firmly positive.
Data from Bitbo shows that the 12 US spot Bitcoin ETFs now hold 1.26 million BTC, worth approximately $149 billion, equivalent to 6% of the eventual 21 million supply.
IBIT alone controls 706,008 BTC, roughly 56% of the cohort, valued at $83 billion. Fidelity’s FBTC sits a distant second at $24.4 billion, while Grayscale’s GBTC retains $21.7 billion after months of redemptions.
