Bitmine Faces $9 Billion Unrealized Loss as Ethereum Falls Below $1,800

TL;DR:

• Bitmine faces nearly $9 billion in unrealized losses after ether fell below $1,800, sending its shares below $17.
• The company holds more than 5.4 million ETH, about 4.5% of circulating supply, worth roughly $10 billion at current prices.
• Bitmine financed purchases mostly through equity, stakes 87% of holdings and earns estimated annualized staking revenue of $276 million, but investors remain focused on ETH weakness and treasury-sector pressure remains elevated overall.

Bitmine’s Ethereum treasury strategy is facing its hardest public test yet after ether fell below $1,800, pushing the company’s estimated paper loss close to $9 billion. Bitmine Immersion Technologies, chaired by Tom Lee, is the largest corporate holder of ETH, but the latest crypto pullback has dragged its stock to the weakest level since its 2025 pivot toward an Ethereum treasury model. The uncomfortable point is scale meeting timing, because a position built for long-term upside is now being marked against February-like lows and a market questioning every corporate crypto balance sheet.

Bitmine shares fell another 5.9% on Wednesday, slipping below $17 and extending their decline to 28% since early May. Ether has also lost more than 20% since early May, when Lee argued that the market’s “mini crypto winter” had likely ended and a new “crypto spring” had begun. That contrast makes the drawdown more jarring, as one of Ethereum’s most visible bulls is now watching the market move sharply against the very thesis he promoted only weeks earlier.

Under Lee’s leadership, Bitmine has accumulated more than 5.4 million ETH in roughly a year, equal to about 4.5% of Ethereum’s circulating supply. At current prices, those holdings are worth about $10 billion, but DropsTab data cited in the report estimates unrealized losses near $8.9 billion. The treasury is enormous, but deeply underwater, creating an uneasy mirror of the broader digital-asset treasury sector, where public companies raise capital to buy crypto and then trade below the implied value of their reserves when prices weaken.

Bitmine’s structure gives it some protection compared with debt-heavy treasury models. The company financed most of its ETH purchases through equity issuance, limiting leverage worries and interest-payment pressure. It also stakes more than 4.7 million ETH, or about 87% of holdings, and operates the MAVAN staking service, with estimated annualized staking revenue near $276 million. The cushion is real, but it is not a cure, because investors are focused on spot ETH weakness today while Lee is still talking about a possible $250,000 ETH future driven by tokenization, AI transactions and corporate staking. That gap between vision and mark-to-market reality is now the stock’s central tension, especially as treasury peers face similar pressure during the renewed weakness.
