BlackRock-linked wallets have sent large amounts of Bitcoin and Ether to Coinbase Prime over recent weeks, with on-chain data putting the total near $3 billion. The latest transfer came on Feb. 9, when roughly 2,400 BTC and 24,760 ETH were moved in a single transaction worth about $248 million.
Moves of this size quickly drew market attention. Traders and blockchain analysts often treat transfers into Coinbase Prime, Coinbase’s institutional venue for large trades and settlement, as signals worth watching. Even so, the source material points to ETF operations as the main explanation, not a discretionary bet on price direction.
A cluster of large transfers hit the chain
Data cited from Lookonchain, Arkham Intelligence, and Solid Intel shows that between Jan. 22 and Feb. 5, at least six major transfers tied to BlackRock’s crypto products were recorded. Those movements totaled about 20,000 BTC and 238,000 ETH, with a combined value of more than $2.2 billion. Analysts also noted that flows into Coinbase linked to the firm exceeded $2 billion by the end of last week.
Among the larger examples, addresses linked to BlackRock sent about 5,080 BTC and 27,196 ETH to Coinbase Prime on Feb. 5, valued at roughly $358 million and $57 million. On Jan. 22, another transfer worth about $603 million involved 3,970 BTC and 82,813 ETH. An earlier move on Jan. 13 included around 3,290 BTC and 5,692 ETH, worth about $303 million.
ETF mechanics are the stated reason
The material ties these flows to the creation and redemption process behind spot crypto ETFs. BlackRock’s products, including iShares Bitcoin Trust (IBIT) and iShares Ethereum Trust (ETHA), hold actual BTC and ETH to back fund shares. If investors buy ETF shares, the fund may need to source more underlying crypto. If investors redeem or sell shares, the fund may need to release assets or move them into settlement channels.
That matters because a transfer to an exchange does not automatically mean BlackRock is selling into the open market. The reported movements can reflect redemptions, liquidity management, or operational transfers between custody and trading infrastructure. The source also says many of the recent transfers were likely linked to ETF outflows or settlement adjustments rather than fresh directional trading.
Why the market is watching
Large on-chain transfers involving BTC and ETH tend to attract attention because they can hint at institutional positioning. In this case, though, the information provided supports a more routine reading: these are part of the plumbing behind regulated crypto ETFs. The activity shows how deeply institutional custody, settlement, and liquidity systems are now tied to the digital-asset market.
