Key Takeaways
Ethereum surged as BlackRock accumulated $314 million and spot ETFs drew $455 million in inflows. Treasury firms added 3.56 million ETH, pushing it toward institutional adoption.
Ethereum [ETH]’s momentum in the latter half of 2025 is proving hard to ignore.
Beyond its record-breaking price surge, the world’s second-largest cryptocurrency is dominating the ETF arena and attracting deep-pocketed institutions.
BlackRock quietly loads up on Ethereum
The latest signal came from BlackRock, which added nearly $315 million worth of ETH in recent transactions.
Blockchain analytics firm Arkham revealed that BlackRock has quietly executed one of its largest Ethereum purchases yet, amassing $314.9 million worth of ETH across multiple transactions.
The world’s top asset manager used ETF-linked wallets to scoop up Ethereum in tranches, with several 10,000 ETH transfers (worth around $46 million each) coming from Coinbase Prime hot wallets.
Smaller frequent buys followed, such as a batch of 2,691 ETH.
This accumulation isn’t happening in isolation.
A new class of “Ethereum Treasury Firms,” publicly traded companies such as BitMine, SharpLink, and ETHZilla have also been adding ETH to their balance sheets.
Collectively, these firms now hold over 3.7 million ETH, nearly 3% of the total supply.
ETH price action and ETF inflows
The timing of these purchases was critical.
Ethereum traded at $4,578.88 at press time, up 3.3% in 24 hours and 9% on the week.
Moreover, on the 26th of August, spot ETH ETFs posted $455 million of inflows, according to Farside Investors.
Such momentum has fueled bullish forecasts, with Tom Lee, Chairman of BitMine and Head of Research at Fundstrat, arguing that ETH remains undervalued and should be trading closer to $6,000.
Is the “Ethereum killer” label no longer valid?
Even now, Solana [SOL], Avalanche [AVAX], Polygon [MATIC], Aptos [APT], and Sui [SUI] compete in niches such as gaming, high-speed transactions, and enterprise adoption.
However, Ethereum has secured its dominance through Layer-2 scaling solutions and its role as the settlement layer of the ecosystem.
As AMBCrypto previously noted, the outdated “Ethereum killer” label no longer applies.
Instead, the industry is evolving into a multi-chain landscape where Ethereum remains the foundation while specialized chains thrive in parallel.
