BlackRock’s Crypto Holdings Balloon As Bitcoin, Ethereum Reach For New ATHs — Here Are The Numbers

BlackRock’s cryptocurrency portfolio has surpassed the $100 billion mark, as Bitcoin and Ethereum push to new all-time highs. The world’s largest asset manager now holds nearly $104 billion in digital assets, and this achievement came as Bitcoin briefly broke above $124,000 on August 14, 2025, to set a new price record before consolidating between $118,000 and $121,000. Ethereum also surged to nearly $4,790, just shy of its 2021 peak of $4,878. 

Bitcoin and Ethereum have been on a price roll in recent weeks, and a large part of this momentum can be attributed to steady institutional inflows into Spot Bitcoin and Ethereum ETFs based in the US. At the forefront of this surge is BlackRock, the world’s largest asset manager, which continues to dominate in terms of assets under management (AUM) and growth in cryptocurrency exposure, particularly in Ethereum in the past two months.

Interestingly, data from Arkham Intelligence shows that BlackRock has crossed the $100 billion mark in terms of total crypto holdings. This interesting milestone is based on a combination of inflows into its ETFs, which has increased its accumulation strategy, and the recent uptick in the price of cryptocurrencies across the board.

Data from Arkham Intelligence shows BlackRock’s total holdings recently hit a peak value of $107 billion when Bitcoin reached a record price of $124,128 yesterday, and Ethereum reached a multi-year price peak of $4,775. At the time of writing, the investment management company is holding 744,240 BTC worth $88.43 billion and 3.2 million ETH, worth approximately $14.78 billion.

At the beginning of 2025, BlackRock’s cryptocurrency portfolio was valued at roughly $54 billion, with the overwhelming majority of that exposure concentrated in Bitcoin. However, the first quarter of the year brought a period of weakness, as Arkham Intelligence data shows the portfolio’s value slid to a low of about $46 billion in early April. From that point on, momentum shifted sharply in the opposite direction. The firm’s total holdings have since climbed by about 124% from April 7 up until the time of writing.

Bitcoin still accounts for more than 85% of BlackRock’s crypto allocation, but the most remarkable growth story in the past eight months has come from Ethereum. In both volume and market value, ETH holdings have expanded at a far more aggressive pace than Bitcoin, surging by over 309% in dollar terms since the start of the year.

At the start of 2025, BlackRock’s Bitcoin reserves stood at approximately 552,000 BTC. Current data indicates that Bitcoin holdings have grown by about 34% over the course of the year. Ethereum’s expansion within BlackRock’s portfolio has been even more notable, as the firm began the year with roughly 1.1 million ETH and has more than doubled its position in just eight months, with the current volume representing a 190% increase.
