- Arkham data reveals over $50M in ETH bought by BlackRock via Coinbase Prime
- Activity suggests long-term accumulation, possibly ahead of broader institutional moves
- Ethereum remains bullish in structure, with potential upside if momentum continues
Something’s brewing on-chain, and if you’re paying attention, it’s hard to ignore. BlackRock — yeah, that BlackRock — just scooped up over $50 million worth of Ethereum, and Arkham was quick to spot the trail.
This isn’t your average whale activity. This is one of the largest asset managers on the planet increasing exposure to ETH, and the timing? Very, very interesting.
Let’s break it down.
Arkham Intelligence posted data pointing to multiple Ethereum purchases by BlackRock, ranging from 9,000 ETH to more than 58,000 ETH.
BLACKROCK IS BUYING ETHEREUM.

All of it sourced through Coinbase Prime. The on-chain footprint shows a steady build-up in balances and profits — and if you’ve been in crypto long enough, you know what that usually precedes: either accumulation before a major catalyst, or positioning ahead of product rollout.
BlackRock deposited 1,249.68 $BTC ($131.55M) into #Coinbase. In total, they deposited 5362.37 $BTC ($560.94M), in the past 2 days.

Maybe both.
Now think about the context. ETH just had its spot ETF approved. The SEC dragged its feet, sure, but it happened. And when institutions start snapping up ETH right after regulatory clarity, it’s rarely random.
This could be part of a wider strategy — not just a bet on Ethereum as a network, but on ETH as digital collateral for future financial infrastructure.
The real question isn’t “why did BlackRock buy?” It’s: “what are they preparing for?”
Because when giants move, it’s rarely for small things.
