With the price of Bitcoin smashing new all-time highs over the last two days, BlackRock’s spot Bitcoin exchange-traded fund has made history. The iShares Bitcoin Trust (IBIT) has become the fastest fund ever to surpass $80 billion in assets under management (AUM).

IBIT Blows Past $80 Billion

BlackRock’s IBIT has pulled off something no other ETF has done so fast. The ETF has officially crossed the $80 billion in assets, making it the fastest ETF in history to hit that milestone. It took the iShares Bitcoin Trust just 374 days, which is approximately five times faster than the previous record holder, the Vanguard S&P 500 ETF (VOO), which took 1,814 trading days to reach $80 billion AUM.

“$IBIT blew through the $80b mark last night, fastest ETF to get there in 374 days, about 5x faster than the previous record, held by $VOO, which did it in 1,814 days,” Bloomberg Intelligence senior ETF analyst Eric Balchunas wrote on X.

IBIT is now the 21st biggest ETF globally by assets, a tremendous achievement for an ETF that debuted on Wall Street just over a year ago.

The firm’s holdings of 706,008 Bitcoin make it the largest institutional holder of Bitcoin, ahead of crypto exchange giant Binance and Michael Saylor’s Strategy. The largest holder of Bitcoin is still presumed to be Bitcoin’s enigmatic creator, Satoshi Nakamoto. Pundits estimate that addresses linked to Satoshi hold roughly 1.1 million BTC, accounting for around 5.2% of Bitcoin’s 21 million supply.

Meanwhile, the dozen spot Bitcoin ETFs locked in over $1.17 billion in inflows on Thursday, notching their second-highest single-day totals since launch as institutional money flooded into cryptocurrencies.

“Total assets for all the spot Bitcoin ETFs crossed $140b for the first time as well,” Balchunas posited. “They took in over $1b last night but it was really the big move up in price that is doing most of the heavy lifting here.”

The massive inflows to Bitcoin ETFs came as the maiden crypto broke a fresh historic high above $118,600.
