BlackRock Bitcoin Fund Witnesses “Head-Turning” Growth, Nears $100 Billion Valuation
The BlackRock iShares Bitcoin Trust ETF (IBIT) is nearing $100 billion in assets under management (AUM). Despite being 438 days old, this ETF has cemented its place as the company’s most profitable.
IBIT’s Headed for the Stars
IBIT hit its near-$100 billion valuation in just 435 days. According to reports, the ETF hit astronomical valuation faster than some legacy funds ever could. For context, the Vanguard S&P 500 ETF (VOO) needed over 1,000 days to reach $100 billion.
Market analysts assert that IBIT is set to become the fastest ETF to reach $100 billion. Eric Balchunas, a Bloomberg analyst, who noted that IBIT was just $2 billion away from $100 billion, describes this uptick as absurd.
Here’s how he captioned an X post detailing IBIT’s stance in BlackRock’s ETF portfolio:
$IBIT a hair away from $100 billion, is now the most profitable ETF for BlackRock by a good amount now based on current aum. Check out the ages of the rest of the Top 10. Absurd. pic.twitter.com/E8ZMI2wynx

The picture tied to Eric’s post shows that IBIT sits pretty on top, with an annual fee revenue of just over $244.5 million. However, the funds in 2nd and 3rd place, iShares Russell 1000 Growth ETF and iShares MSCI EAFE ETF, are valued at $219.3 million and $219 million, respectively. Note that both ETFs were launched 25 and 24 years ago, respectively. This just goes to show how otherworldly IBIT is.
IBIT’s Value Rise Coincides With Bitcoin’s All-Time High
The 6th of October wasn’t just the day that IBIT’s near-$100 billion aum valuation made waves, it was the day that Bitcoin’s overall value rose to a new high of $125,800.
This rise was trailed by a week when institutional inflows tipped the scale, for good. For context, global crypto exchange-traded products (ETPs) attracted $5.95 billion, which doubles as the highest total made in one week.
U.S. spot Bitcoin ETFs accounted for a whopping $5 billion of that amount, while IBIT led the charts in net inflows with a whopping $3.2 billion. Little wonder that BlackRock’s ETF hit $100-billion valuation territory the following week!
Conclusion
IBIT is BlackRock’s best performing ETF currently. This Bitcoin is almost at a $100 billion aum valuation, under two years of its launch. Nonetheless, investors must still exercise caution before investing in related financial investments. Don’t want FOMO steering you towards digital assets that won’t yield dividends in the long run?
