On December 3, 2025, asset management giant BlackRock transferred 44,140 Ethereum (ETH), valued at approximately $135 million, to the Coinbase Prime platform. This substantial move occurred despite a strong recovery in the cryptocurrency market, with Ethereum's price surging over 7% to reach a multi-week high of $3,100.
The transaction, tracked by on-chain analytics firm Lookonchain, was executed in four batches of 10,000 ETH each, followed by a final transfer of 4,140 ETH. This activity is part of a consistent, month-long trend of BlackRock offloading significant amounts of both Bitcoin and Ethereum from its exchange-traded fund (ETF) products.
The sell-off coincides with reported net outflows of roughly $89 million from BlackRock's Ethereum ETF (ETHA), a contrast to inflows seen at competitors like Fidelity and Grayscale. Analysts interpret the transfer as a routine rebalancing operation required to align the fund's on-chain reserves with investor redemptions, rather than a speculative market bet. The move underscores the deep integration of traditional finance infrastructure with crypto markets, with Coinbase Prime serving as the central hub for custody and execution for major ETF issuers.
While BlackRock has not publicly commented on its strategy, the timing of the sales during a bullish market phase has fueled speculation. Market participants are debating whether the firm is engaging in tactical profit-taking, hedging against volatility, or signaling a broader shift in its long-term outlook on digital assets.
