BlackRock, the world’s largest asset manager with approximately $11.6 trillion in assets under management, currently holds over 567,000 Bitcoin (BTC), valued at over $47.8 billion—making the asset manager one of the largest holders of BTC globally.
According to Arkham Intelligence, the most recent BTC acquisition by BlackRock occurred on March 14, when a Coinbase Prime wallet transferred 268 BTC, worth over $22 million, to the asset manager’s iShares Bitcoin ETF (IBIT) wallet.

Data from Arkham also reveals that BlackRock holds over 1.2 million Ether (ETH), valued at over $2.3 billion, roughly 70 million USDC stablecoins, alongside a diverse range of altcoins.
Bitcoin exchange-traded funds (ETFs) are widely recognized as some of the most successful launches in the history of ETFs, as asset managers like BlackRock drive significant liquidity into cryptocurrency markets, disrupting the cyclical capital rotation that typically characterizes crypto investments.

Crypto ETFs Experience Four Weeks of Outflows
Crypto ETFs faced four consecutive weeks of outflows during February 2025 and early March due to macroeconomic uncertainties and fears surrounding a potential prolonged trade war.
According to CoinShares, the outflows during the recent market downturn tallied up to $4.75 billion, with March 9 alone seeing $876 million in outflows.
For that week, BlackRock’s iShares Bitcoin fund experienced $193 million in outflows, contributing to a total of $756 million in month-to-date outflows across all BTC ETFs.

Despite heightened volatility and macroeconomic uncertainties, BlackRock added IBIT to its model portfolio in February 2025.
BlackRock’s model portfolios consist of preset investment strategies featuring a variety of diversified financial instruments paired with various risk profiles. The portfolios are marketed to asset managers, who present these investment strategies to their clients.
The inclusion of an ETF or an asset into a model portfolio can significantly amplify inflows as it attracts new capital.
In the case of IBIT, this strategy allows passive investors to gain exposure to Bitcoin without requiring them to manage the digital asset directly or conduct on-chain transactions.
