BlackRock is making an institutional power play on Ethereum and it’s all happening on-chain.
According to Arkham Intelligence, the world’s largest asset manager has bought over $750 million worth of Ethereum in June 2025 alone, all via Coinbase Prime. Even more remarkably, BlackRock hasn’t sold a single ETH during this entire period.
“BlackRock has now bought over $750M of ETH in June alone and has never sold a single ETH,” Arkham posted on June 18. “The BlackRock entity currently holds 1.5M ETH ($4.24B).”

The Breakdown: Daily Buys, Zero Sells
Arkham’s tracking reveals that BlackRock has consistently accumulated ETH almost every single day this month. Their purchases include:
- $73.2M on June 4
- $34.7M on June 5
- Over $500M within 10 days
- Continuous buys leading to a total of ~1.642 million ETH held
Every transaction has been executed on-chain via Coinbase Prime, with zero outgoing ETH from the wallet is a clear sign of long-term conviction.
$4.24 Billion in Ethereum - A Historic Accumulation
BlackRock’s Ethereum accumulation in June isn’t just substantial it’s historic. No other traditional financial institution has moved this aggressively into a crypto asset in such a short time frame.
Here’s a look at BlackRock’s top crypto and asset holdings as of today, June 19, 2025, based on data from Arkham Intelligence:
| Asset | Holdings | Value |
|---|---|---|
| BTC | 670.437K BTC | $69.84B |
| ETH | 1.642M ETH | $4.1B |
| SPX | 83.22K SPX | $111.51K |
| COLLE | 205.85M COLLE | $46.9K |
| JOE | 239.839K JOE | $10.51K |
Total purchases in June exceed 560,000 ETH, valued over $750 million, with BlackRock’s total ETH holdings nearing 1.65 million ETH (~$4.24B).
This makes BlackRock one of the most transparent and aggressive institutional holders of Ethereum on record — and the wallet remains untouched for sales.
This positions BlackRock as one of the largest institutional ETH holders in the world — and it’s entirely traceable on-chain.
Market Timing: Buying the Dip
Notably, this aggressive buying coincided with an 8% ETH price dip in mid-June. Rather than flinch, BlackRock leaned in, signaling high confidence in Ethereum’s long-term trajectory and upcoming ETF flows.
