BlackRock’s IBIT spot Bitcoin ETF has become the fastest ever to reach $70 billion in assets under management. It did this in just 341 trading days, way quicker than anyone thought.
IBIT is a spot Bitcoin ETF. That means it directly holds Bitcoin instead of just tracking it. According to ETF analyst Eric Balchunas, it “blew through $70 billion” in just 341 days—over five times faster than the previous record held by the gold ETF GLD, which took 1,691 days (Watcher Guru).
This run isn’t a one-off. IBIT had a 31-day streak of daily inflows, meaning investors kept putting money in every day for a month . That’s a strong sign people want Bitcoin exposure in a simple, regulated way.
As of early June, the fund held over 661,000 BTC, making it one of the largest institutional holders—still behind Satoshi Nakamoto but ahead of big players like Binance and Michael Saylor’s firm (Cointelegraph).
BlackRock’s success also means big money. Bloomberg reports IBIT now brings in more annual fee revenue than BlackRock’s S&P 500 ETF—though the S&P fund has many times more assets (Watcher Guru). That shows investor demand for Bitcoin is very strong.
Conclusion:
IBIT’s record pace proves spot Bitcoin ETFs are more popular than ever. With growing inflows and big institutional backing, this could pull more investors into crypto. Next stops: even higher AUM and wider Bitcoin acceptance.
