Despite its current downtrend, Bitcoin’s integration into traditional finance remains an unprecedented success for its major players, such as global asset management leader BlackRock. A “big surprise” that now represents its main source of revenue.
BlackRock’s Bitcoin ETFs have $100 billion in assets under management
It will soon be two years since the U.S. stock market officially integrated spot Bitcoin ETFs, in January 2024. A minor revolution for its major fund managers, given a launch and results far exceeding all forecasts.
Indeed, these exchange-traded funds linked to the BTC price will quickly establish themselves as the best launches recorded over the past 30 years, among a list of competitors involving several thousand financial vehicles of this type.
A success that was clearly unexpected, according to Cristiano Castro, Director of Business Development at BlackRock Brazil, in an interview with the financial media outlet Estadao E-Investidor. Indeed, he describes these results as a “big surprise,” with assets under management now approaching $100 billion.
When we launched the product, we were optimistic, but we didn’t expect it to be on this scale.

This amount will be distributed among the various Bitcoin ETFs offered by BlackRock, such as the undisputed star IBIT, established in the U.S. market, as well as the local Brazilian version, IBIT39. The iShares Bitcoin Trust (IBIT) alone has reached $70 billion in assets since its launch and generated approximately $245 million in annual fees.

Its most profitable revenue source
To fully understand the scope of BlackRock’s Bitcoin ETF success, it is important to note that this global leader in asset management alone holds more than 1,400 ETFs, with a total of $13.4 trillion in assets under management.
Within this vast portfolio, these Bitcoin-related funds have now emerged as its most profitable revenue source, with the share of BTC held on behalf of its clients exceeding 3% of the total supply of this cryptocurrency.
This reality is further reinforced by the confidence expressed by the giant BlackRock through its Strategic Income Opportunities portfolio, whose stake in the IBIT was recently increased to 14%, despite the current market turbulence.
In fact, Cristiano Castro is not particularly concerned about the current increase in net outflows in the spot Bitcoin ETF market. This reaction is considered fairly typical among retail investors and does not call into question the ability of ETFs to establish themselves as “highly liquid and powerful tools designed to enable people to manage cash flows.”
