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.
