BlackRock, the world’s largest asset manager, has expanded its Bitcoin and Ethereum holdings to record levels. Data from Arkham Intelligence shows its iShares Bitcoin ETF (IBIT) wallets now control more than 735,000 BTC valued at $86 billion. Recent on-chain activity revealed multiple transfers of 300 BTC each, worth $37 million apiece, funneled through Coinbase Prime.
This marks a major increase from March 2025, when BlackRock was reported to hold 567,000 BTC valued at $47.8 billion. The rapid accumulation now places the firm among the largest Bitcoin holders globally, surpassing even MicroStrategy, which currently holds about 628,946 BTC worth $54.93 billion.
BlackRock’s crypto strategy extends beyond Bitcoin. Its Ethereum ETF (ETHA) wallets recently received deposits of 5,900 ETH alongside multiple 10,000 ETH transfers within just two days. Combined, these additions exceed $121 million, pushing the fund’s Ethereum holdings to over $14 billion.
The surge in BlackRock’s crypto exposure underscores the strength of ETF-driven adoption. Bitcoin ETFs remain among the most successful launches in financial history, attracting billions in trading volume since approval in 2024.
At press time, Bitcoin trades at $117,789, easing from its weekly high of $124,000. Despite modest weekend movements, BlackRock’s growing position highlights deepening institutional confidence in crypto assets.
