Blackrock’s iShares Bitcoin Trust ETF (IBIT) Achieves Unprecedented Success
Blackrock’s iShares Bitcoin Trust ETF (IBIT) has reached a remarkable milestone, with assets under management (AUM) approaching $100 billion in just 435 days since its inception. This impressive feat has catapulted IBIT to become the most profitable ETF for Blackrock, outpacing other funds that have been in operation for decades.
According to Eric Balchunas, Senior ETF analyst at Bloomberg, IBIT has generated more income for Blackrock than some of its other funds have in decades. The top 10 sales generators for Blackrock highlight the significant age difference, with the iShares Russell 1000 Growth ETF, which has been active for 25 years, holding assets of $121.8 billion. In contrast, IBIT has achieved its remarkable success in a fraction of the time.
Fee Structure and Profitability
IBIT’s fee structure, which charges 0.25% for assets, has contributed to its impressive profitability. With annual sales of around $244.5 million at the current level, the fund’s considerable asset base and relatively high fee have driven its success. In comparison, Blackrock’s core S&P 500 ETF charges zero base points, highlighting the significance of IBIT’s fee structure in its profitability.
Balchunas also noted that IBIT is just $2 billion away from reaching the $100 billion threshold and is on track to break the record for the fastest ETF to achieve this milestone. The current record holder, the Vanguard S&P 500 ETF, took 2,011 days to reach this threshold, while IBIT is expected to achieve it in about a fifth of the time.
Bitcoin ETF Inflows and Market Performance
The success of IBIT extends beyond individual fund comparisons, with the Bitcoin ETF drawing significant inflows. On October 5, IBIT and Blackrock’s iShares Ethereum Trust ETF (ETHA) attracted monthly inflows of $10 billion, securing third and fourth place in all ETFs for monthly inflows. According to James Seyffart, Bloomberg ETF analyst, Bitcoin ETFs have seen $3.3 billion in inflows for the week, with year-to-date inflows reaching $24 billion and lifetime inflows approaching $60 billion.
The $60 billion milestone marks a new record for the product category since its inception in January 2024. The surge in ETF inflows has been accompanied by a significant increase in Bitcoin’s price, which reached new all-time highs and crossed $125,500 on October 6. The cumulative flow diagram illustrates a steady acceleration of inflows, from $12 billion in March 2024 to $40.25 billion in February 2025, followed by a jump to $59.54 billion in October 2025.
