BlackRock has crossed a new milestone in its digital asset strategy, with cryptocurrency holdings now at $103.98 billion as of August 14, 2025, according to Finbold analysis of data from blockchain intelligence platform Arkham.
The portfolio includes $89.27 billion in Bitcoin (743,310 $BTC) and $14.71 billion in Ethereum (3.2 million $ETH).
Notably, this marks a staggering $49.15 billion net increase since the start of 2025, when BlackRock’s crypto holdings stood at $54.83 billion, comprising $51.16 billion in $BTC and $3.59 billion in $ETH.
BlackRock’s recent Ethereum accumulation
Notably, the pace of Ethereum accumulation has accelerated sharply in recent months. At the start of the year, BlackRock held roughly 1.07 million $ETH worth $3.59 billion. By June 30, that figure had climbed to $4.21 billion, and in just six weeks since, the position has more than tripled to $14.71 billion.
In percentage terms, Ethereum holdings have surged 198.64% in volume and over 309% in dollar value since January.
By contrast, while Bitcoin still dominates BlackRock’s crypto portfolio accounting for over 85% of holdings, $BTC accumulation has grown at a slower relative pace, rising 34.52% in volume and 74.48% in value since January.
The rapid build-up in Ethereum exposure comes as institutional demand for $ETH spikes on the back of Ethereum ETF inflows, broader DeFi adoption, and rising optimism around Ethereum’s scaling roadmap.
With $12.53 trillion in total assets under management as of June 30, BlackRock’s $100 billion-plus crypto position represents less than 1% of its total portfolio, but sends a clear signal about the firm’s conviction in digital assets.
