BlackRock's Bitcoin ETFs have become the company's most profitable product line globally. The statement came from Cristiano Castro, Business Development Director at BlackRock Brazil. This data is noteworthy considering that BlackRock, the world's largest asset manager, manages more than 1,400 ETFs and has total assets exceeding $13.4 trillion. Speaking to Brazilian media at the Blockchain Conference in São Paulo, Castro described the growth of Bitcoin ETFs as a “big surprise.” He said allocations to the company's BTC ETFs, including US-based IBIT and Brazil's IBIT39, are approaching nearly $100 billion. “We were optimistic at launch, but we didn't expect this level of growth,” he said. Launched in January 2024, the US spot Bitcoin ETF IBIT reached $70 billion in assets in just 341 days, becoming the fastest ETF in history to surpass this threshold. According to SoSoValue data, the fund's current net assets are $70.7 billion.

IBIT also generated approximately $245 million in annual trading fee revenue as of October 2025. BlackRock's global distribution network and institutional demand following regulatory approval for spot Bitcoin ETFs in the US are cited as key drivers of IBIT's rapid rise. The fund currently holds over 3% of the Bitcoin supply. Following IBIT, the company has also launched various BTC-related products in various countries. Castro also addressed the recent outflows from Bitcoin funds, stating that this volatility was natural. He noted that individual investors react more quickly to price drops, saying, “ETFs are highly liquid and powerful instruments. They were created to manage flows.” *This is not investment advice.
