BlackRock Exec Says Bitcoin ETFs Becoming A Major Revenue Source Was A ‘Big Surprise’
Overview
Spot Bitcoin exchange-traded funds (ETFs) have emerged as a significant narrative within the cryptocurrency sector over the past two years. These investment products allow individuals to engage with the cryptocurrency market without needing to directly own digital assets, leading to increased institutional adoption.
Key Developments
At the Blockchain Conference 2025 held in São Paulo, BlackRock’s business development director in Brazil, Cristiano Castro, revealed that Bitcoin ETFs have become the largest revenue source for the firm. This development was unexpected for BlackRock, the world’s largest asset manager.
Castro noted that while BlackRock was optimistic about the launch of Bitcoin ETFs, they did not anticipate such substantial success. He mentioned that the assets related to the Bitcoin ETFs, specifically referencing IBIT in the U.S. and IBIT39 in Brazil, approached significant allocation amounts. BlackRock has over 1,400 exchange-traded products globally and manages $13.4 trillion in assets.
The U.S.-based Bitcoin fund, known as IBIT, surpassed $70.7 billion in net assets, marking a milestone as the first ETF to reach this level. Despite a slowdown in the U.S. Bitcoin ETF market, BlackRock’s IBIT continues to outperform other recently launched ETFs. Reports indicate that IBIT generated approximately $245 million in annual fees.
When addressing the recent outflows from BlackRock’s Bitcoin ETF amid market fluctuations, Castro described such trends as “perfectly normal.” He explained that the liquidity of ETFs allows investors to manage their capital and cash flow effectively. Castro noted that the withdrawals were expected due to the product’s significant retail investor ownership, which tends to react to price corrections. Recently, the iShares Bitcoin Trust experienced a net outflow of $113.72 million, contributing to a weekly total of negative $137.01 million and marking the fifth consecutive week of withdrawals.
