BitMine Becomes Ethereum’s Biggest Corporate Holder With 3.3 Million ETH in Reserves
This article was first published on The Bit Journal.
BitMine Immersion Technologies has jumped into the top tier of institutional crypto treasuries with total crypto, cash and “moonshot” investments of $14.2 billion, anchored by a whopping 3,313,069 ETH position; seemingly the largest Ethereum treasury in the world.
Chairman Tom Lee has described the strategy as pursuing what the firm calls its “alchemy of 5%” of Ethereum’s total supply.
For BitMine Ethereum holdings, this means $ETH is no longer just a speculative token, but a corporate reserve asset.
BitMine Ethereum Holdings Scale
BitMine’s recent announcement divulged that they now hold 3.31 million ETH tokens, or roughly 2.8% of Ethereum’s total supply.
The breakdown includes 192 BTC, $305 million in unencumbered cash, plus their “moonshot” investments, all totaling $14.2 billion.
Earlier in August, they reported 1.71 million ETH and crypto + cash assets of $8.8 billion.
How BitMine Built Its ETH Treasury
BitMine’s ETH strategy started with a $250 million private placement announced on June 30 2025, specifically for ETH accumulation.
From there; they scaled fast and by July; they had over 300,000 ETH worth over $1 billion.
By early August, they had 833,137 ETH ($2.9 billion). By August 24th; they had 1.71 million ETH with $8.8 billion in assets.
BitMine’s move resonates with a trend in corporate treasuries where instead of just Bitcoin, Ethereum is becoming a reserve asset. By holding ETH as a core treasury holding, BitMine is signaling that they believe in ETH’s role in decentralized finance, staking, smart-contracts and tokenization.
Tom Lee drew a historical parallel, calling the ongoing evolution: “[The] end of Bretton Woods … as transformational to financial services in 2025 as ending Bretton Woods was 54 years ago.”
Market and Investor Impacts
BitMine’s ETH accumulation has had effects. Their stock (BMNR) has gone up big time and is now one of the most traded stocks in the US with daily volumes in the billions.
Big investors like ARK Invest, Bill Miller III, Founders Fund (via Peter Thiel) and others are also reportedly behind the strategy.
For ETH markets, big public-treasury holders like BitMine set a new precedent: corporate accumulation, staking and ecosystem integration are part of how ETH is valued.
Conclusion
Going forward, market observers could monitor include how BitMine manages and deploys its ETH; whether it stakes, uses it for DeFi yield or holds it passively. The firm’s target of 5% of ETH supply is ambitious.
Also; how other companies respond; will more firms add ETH to their reserves? The whole ecosystem may change if BitMine Ethereum holdings becomes the corporate crypto strategy.
Finally; how this accumulation impacts ETH tokenomics, staking; supply concentration and market perceptions will make headlines.
