BlackRock moves $286 million in Bitcoin and Ether to Coinbase Prime

The world's largest asset manager moved a substantial chunk of crypto to its custodial partner, but the transaction is more operational plumbing than market signal.

BlackRock transferred 54,096 ETH valued at approximately $132 million and 2,015 BTC worth nearly $154 million to Coinbase Prime, according to on-chain data tracked by Arkham Intelligence. The ETF-linked transaction involved roughly $286 million in combined crypto assets.

The deposit, representing a substantial volume of digital assets, is tied to the operational management of BlackRock’s iShares Bitcoin Trust (IBIT) and iShares Ethereum Trust (ETHA).

Coinbase Prime serves as the primary custodian and execution agent for BlackRock’s crypto ETFs. That means it handles everything from buying and selling to settlement and redemptions, all as outlined in BlackRock’s regulatory filings with the SEC.

On-chain monitoring services, including both Arkham Intelligence and Lookonchain, have tracked a recurring pattern of large transfers between BlackRock-linked wallets and Coinbase Prime. Historical deposits have ranged from tens of millions to hundreds of millions of dollars in value. One notable transfer in December 2025 involved around 2,019 BTC and 29,928 ETH, worth approximately $273M at the time.

Bitcoin changed hands around $76,800 at press time, recovering from a slide toward $75,000 following the CLARITY Act setback and the Federal Reserve’s rate hike.

Ether was trading at around $2,460, up 2% in the past 24 hours.
