BlackRock ETF funds moved $49m into BTC and ETH on Coinbase Prime, extending a months-long pattern that turns ETF flows into a live gauge of institutional position.
Summary
- Arkham data shows that BlackRock ETF funds have moved 8,513 ETH (about $19.14 million) and 416.654 BTC (about $29.86 million) to Coinbase Prime.
- These flows came from the company’s Ethereum ETF ETHA and Bitcoin ETF IBIT, underscoring how ETF vehicles now lead institutional size through centralized brokerages.
- The transfer extends a months-long pattern of BlackRock using Coinbase Prime for large ETF-related reallocations as crypto markets react to major signal changes.
BlackRock moved 8,513 ETH and 416.654 BTC, worth about $49 million in total, from wallets linked to the ETF to Coinbase Prime, according to Arkham on-chain data transmitted by BlockBeats and regional stores.
BlockBeats reported that, about an hour before publication on April 8, the asset manager’s Ethereum ETF sent 8,513 ETH, worth about $19.14 million, to the Coinbase Prime address, while iShares Bitcoin Trust IBIT transferred 416.654 BTC, worth about $29.86 million, to the same place.
Coinbase Prime, the institutional arm of the exchange, offers decentralized custody, block trading and reporting tools designed for ETF issuers and other large asset managers.
The latest change is part of a broader pattern of BlackRock using Coinbase Prime as its main hub for ETF-related crypto flows. On March 25, an address associated with ETHA deposited 15,400 ETH, worth about $32 million, to Coinbase Prime, a data account Data Nerd noted in comments cited by Coinness. TechFlow’s report, which summarizes Arkham’s monitoring, similarly found that BlackRock moved 11,780 ETH (about $25.75 million) and 634 BTC (about $45.35 million) to Coinbase Prime via ETHA and IBIT in late March. Earlier this year, a Binance Square post citing Arkham showed BlackRock exchanging 3,970 BTC (about $356.7 million) and 82,813 ETH (about $247.1 million) on Coinbase Prime during a single trading window, accompanied by “significant net outflows” from ETFs.
These flows highlight how ETF-driven institutional activity continues among the few top regulated brokers, just as the prices of Bitcoin and Ethereum fluctuate on big data, central bank expectations and monetary easing. Arkham described Coinbase Prime as “a dedicated platform for institutional clients who need complex trading, storage, and reporting tools,” and notes that such transfers often precede rebalancing, creation or redemption in the ETF structure rather than speculative trading. As ETF prices deepen and more traditional currencies enter the market, BlackRock’s on-chain tracker moves to Coinbase Prime to become a real-time barometer of the institutional position in BTC and ETH—one that can’t stray too far from the noise of retail-dominated areas.
