BlackRock accumulated over 150K ETH via Coinbase Prime in 10 days, signaling aggressive positioning in Ethereum markets.
On-chain flows show BlackRock's ETH wallet hit $500M, with only one outbound move, pointing to a long-term accumulation strategy.
Ethereum ETF inflows surged in tandem with BlackRock’s buying, reinforcing institutional conviction in ETH exposure through Q2.
A recent analysis reveals that BlackRock has acquired over $500 million in Ethereum (ETH) within ten days, marking one of the largest institutional accumulation events in recent months. The wallet activity, visualized in Arkham’s network interface, highlights large-scale ETH inflows originating from Coinbase Prime and directed to BlackRock’s ETHA wallet.
Centralized wallet flows identified in the Arkham data
According to a report by Arkham, “wallet interaction surged during Q3 and Q4 of 2024,” with accumulation intensifying until early December. A blue-aura central node, representing BlackRock’s ETHA wallet, aggregated ETH from hundreds of addresses, forming a dense cluster of inflows. Green lines dominated the left side of the flow chart, representing consistent accumulation in March, June, and August 2024.
Redirectional activity began in January 2025, as outbound red lines sharply increased, targeting secondary hubs likely linked to exchanges or institutional custodians. These movements peaked in April and May, suggesting redistribution to high-volume, potentially custodial wallets. The chart confirms “major asset aggregation and redistribution,” signaling a shift from holding to strategic positioning.
Ethereum ETF inflows align with institutional accumulation
BlackRock’s sudden Ethereum activity coincides with accelerating net inflows into U.S. Ethereum spot ETFs, with key movement tracked since January. BlackRock’s ETH ETF structure includes direct exposure to spot Ethereum, with custodial services managed by Coinbase Prime and asset management split across multiple affiliated trust vehicles.
The firm aims to establish a multi-asset crypto portfolio anchored in ETH and BTC. The ETF saw consistent weekly inflows between April and early June, peaking with daily additions between 20,000 and 60,000 ETH. The announcement follows BlackRock’s prior success with its Bitcoin ETF, which climbed into the top 25 by AUM despite being less than a year old.
On-chain data reveals $500M in tracked ETH transfers
Transaction logs confirm that within one week, BlackRock’s ETHA wallet received multiple high-value deposits from Coinbase Prime, including three deposits exceeding $70 million each. The most recent transfer, 10,000 ETH worth $25.16 million, occurred 23 hours ago, while earlier transfers ranged between 7,241 and 28,936 ETH per day.
The only outbound transaction within the timeframe was 140.651 ETH to a Coinbase Prime deposit address. These patterns suggest heavy front-loading of ETH ahead of broader market moves. The cumulative volume from the seven days totaled more than 150,000 ETH, translating to $446 million, with continued inflows indicating the trend is still active.
ETF net inflow charts show renewed ETH investor confidence
The chart below titled Total Ethereum Spot ETF Net Inflow (ETH) shows January-to-February net inflows exceeding 120,000 ETH before correcting in March. Mid-April marked a reversal with inflows returning and Ethereum’s price tracking upward. Since May, consistent green bars between 20,000 and 60,000 ETH confirm renewed institutional conviction.
Lifetime cumulative inflows across all $ETH ETFs have reached all-time highs. A $25.3 million inflow was recorded just yesterday. Grayscale and BlackRock now account for a majority of inflow volume, reinforcing ETH’s rising institutional demand.
