BlackRock’s iShares Bitcoin Trust (IBIT) crossed $80 billion in assets under management on July 10, becoming the fastest exchange-traded fund (ETF) to reach the threshold in 374 trading days.

Bloomberg senior ETF analyst Eric Balchunas noted on X that IBIT outperformed the Vanguard S&P 500 ETF (VOO), which took 1,814 days to accumulate the same asset base, and surpassed comparable milestones for international-equity funds IEFA (2,034 days) and IEMG (2,089 days). 

The attached performance chart shows IBIT’s trajectory surpassing that of its peers well before its first anniversary. At $83 billion as of late July 11, 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, the third-largest daily haul recorded for these products, according to CoinShares head of research James Butterfill. 

Farside Investors data added that IBIT led with $448.5 million, 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 large share of industry inflows, yet still leaves the group’s net figure firmly positive.

Bitbo data show 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.
