Tom Lee’s Bitmine Immersion Technologies began trading on the New York Stock Exchange today under the ticker BMNR, marking one of the most aggressive corporate Ethereum bets in history. The company now holds 4.803 million ETH worth roughly $10.2 billion, making it the largest Ethereum treasury in the world and the second-largest corporate crypto treasury overall, behind only Strategy’s Bitcoin hoard.
Chasing 5% of All ETH
Bitmine’s stated goal is to control 5% of the total Ethereum circulating supply. At 3.98% today, it is close. That level of concentration in a single company’s hands raises questions that the market is still sorting through. If Bitmine hits its target and holds, it would own more ETH than the Ethereum Foundation itself.
The thesis is not just accumulation for its own sake. Bitmine has staked the majority of its position, generating what the company calls $196 million in annualized staking rewards at a 2.78% yield on the staked portion. At full deployment, it projects $282 million in annual staking revenue. That recurring income is the core differentiator from Strategy’s model. Bitcoin pays no yield. Staked ETH does.
The $4 Billion Buyback
Alongside the NYSE uplisting announcement, Bitmine expanded its share repurchase program from $1 billion to $4 billion. That is a significant commitment for a company whose entire market cap was a fraction of that figure just months ago.
The buyback signals confidence in the spread between the company’s stock price and its net asset value per share. If ETH continues to appreciate and the discount to NAV persists, the company can buy back shares cheaply and retire them, compounding the per-share ETH exposure for remaining holders. It is the same logic MicroStrategy used to justify aggressive buybacks alongside its Bitcoin purchases.
Why Ethereum Over Bitcoin?
Bitmine’s choice of ETH over BTC reflects a deliberate thesis about yield-generating assets. Bitcoin is a pure store of value play. Ether, as a staked asset on a proof-of-stake network, generates real cash flow. That cash flow can fund operations, cover debt service, or fund further ETH purchases, creating a self-reinforcing loop.
Staking rewards are not risk-free. Ethereum’s protocol could cut yields through governance decisions. Regulatory treatment of staking rewards in the United States remains ambiguous. And concentration risk at this scale means Bitmine’s own selling pressure could move the market against itself if it ever needed to unwind.
Institutional Appetite for Ethereum
Bitmine’s move comes as broader institutional appetite for Ethereum deepens. Major banks have begun moving segments of the global repo market onto Ethereum infrastructure. Spot ETH ETFs have gathered tens of billions in net inflows. The Ethereum Foundation completed a 70,000 ETH staking commitment of its own.
Bitmine is the most visible expression of a thesis that Ethereum is not just infrastructure but a yield-bearing reserve asset. Whether the stock trades at a premium or discount to its ETH holdings will be the market’s verdict on whether that thesis holds.
Total crypto and cash holdings stand at $11.4 billion. The company will report its first full quarter of NYSE-level disclosures in the coming weeks, giving investors a cleaner look at staking revenue, operating costs, and how aggressively it continues to accumulate.
