BlackRock’s iShares Bitcoin Trust ETF (IBIT) has approached $100 billion in assets under management, making it the firm’s most profitable ETF despite its launch just 435 days ago.
Bloomberg senior ETF analyst Eric Balchunas noted on Oct. 6 that IBIT now generates more revenue for BlackRock than funds that have been operating for decades.
The age disparity stands out sharply in BlackRock’s top 10 revenue generators. At one year old, IBIT outearns the iShares Russell 1000 Growth ETF, which has been operating for 25 years and holds $121.8 billion in assets.
The iShares MSCI EAFE ETF and the iShares Core S&P 500 ETF, despite managing $68.4 billion and $701 billion, respectively, also trail IBIT in profitability over 24 years of operation.
IBIT charges a 0.25% fee on assets, generating approximately $244.5 million in annual revenue at current levels.
The fund’s profitability stems from both its substantial asset base and relatively high fee compared to BlackRock’s Core S&P 500 ETF, which charges zero basis points.
Balchunas also shared that IBIT sits $2 billion away from the $100 billion threshold and is on track to shatter the record for the fastest ETF to reach that milestone.
The Vanguard S&P 500 ETF currently holds that record at 2,011 days. IBIT will complete the journey in roughly one-fifth of that time.
The Bitcoin ETF’s velocity extends beyond individual fund comparisons. IBIT and BlackRock’s iShares Ethereum Trust ETF (ETHA) pulled in $10 billion in monthly inflows as of Oct. 5, ranking third and fourth among all ETFs for monthly flows.
Bloomberg ETF analyst James Seyffart highlighted that Bitcoin ETFs collectively pulled in $3.3 billion in the week ending Oct. 3, pushing year-to-date inflows to $24 billion and lifetime flows to approximately $60 billion.
The $60 billion mark represents a new high-water mark for the product category since launch in January 2024.
Bitcoin hit new all-time highs following a surge in ETF inflows, briefly crossing $125,500 on Oct. 6.
The cumulative flow chart shows a steady acceleration from $12 billion in March 2024 to $40.25 billion in February 2025, followed by a jump to $59.54 billion by October 2025.
