IBIT Rockets to $83 Billion, Fueling Spot Bitcoin ETF Boom Past $140 Billion
Blackrock’s iShares Bitcoin Trust (IBIT) has set a new industry benchmark, becoming the fastest exchange-traded fund (ETF) to reach $80 billion in assets under management (AUM). The milestone was achieved in just 374 days, nearly five times faster than the previous record-holder, Vanguard’s S&P 500 ETF ($VOO), which took 1,814 days.
According to a tweet by Eric Balchunas, Senior ETF Analyst for Bloomberg, IBIT surged to $83 billion in AUM on Thursday, July 10, ranking it as the 21st largest ETF in the world.

This came as BTC hit a new all-time high of more than $118,000, with the rapid growth of Blackrock’s IBIT underscoring investor appetite for regulated exposure to bitcoin through traditional financial vehicles.
The broader market for spot bitcoin ETFs has also crossed a significant threshold, with total assets managed across all providers now exceeding $140 billion. That figure reflects continued inflows from both institutional and retail investors seeking access to crypto in a regulated format.
