Catenaa, Tuesday, December 2, 2025- BlackRock’s bitcoin ETFs have overtaken all other products as the firm’s most profitable line, according to Cristiano Castro, director of business development at BlackRock Brazil.
The US-listed IBIT ETF, launched in January 2024, reached $70 billion in assets in just 341 days, generating an estimated $245 million in annual fees.
The ETF’s rapid adoption follows regulatory approval in the U.S. and growing institutional interest. IBIT currently holds more than 3% of total bitcoin supply.
Other BlackRock bitcoin products, including Brazil’s IBIT39 and overseas BTC-linked ETPs, have also seen strong inflows, contributing to a near $100 billion allocation across its bitcoin funds.
Castro noted that outflows tied to price volatility are normal, and ETFs provide investors with liquidity and flexibility to manage positions.
BlackRock’s Strategic Income Opportunities Portfolio recently increased its IBIT holdings by 14%, demonstrating continued institutional confidence in the product.
The ETF’s growth far outpaced other launches in the past decade. Net inflows in the first year exceeded $52 billion. BlackRock, which manages over 1,400 ETFs globally and holds more than $13.4 trillion in assets under management, said the scale of adoption surprised even internal forecasts.
