BitMine Immersion Technologies, the world’s largest publicly traded Ethereum treasury company, is now sitting on approximately $8 billion in unrealized losses, a staggering figure that has turned its chairman Tom Lee’s high-conviction ETH bet into one of the most closely watched stress tests in crypto.
The company accumulated 5.28 million ETH at an estimated total cost of around $16.97 billion, representing nearly 4.4% of Ethereum’s entire circulating supply. With ETH now trading below $2,000 and down more than 60% from its 2025 peak of $4,946, the fair value of BitMine’s holdings has been cut roughly in half, leaving the treasury approximately $8 billion underwater on a mark-to-market basis.
BMNR shares have fallen around 88% from their peak of $161 reached last July, when the company first announced its Ethereum treasury strategy and trading was halted multiple times in a single day due to extreme volatility.
Lee’s response: it’s a feature, not a bug
Tom Lee, co-founder of Fundstrat and BitMine’s chairman, has not flinched publicly. When pressed on the mounting losses, he responded directly: “BMNR will see ‘unrealized’ losses on our holdings of ETH during these times. It’s not a bug, it’s a feature.”
He drew a parallel to index ETFs that also carry unrealised losses in market downturns, and reiterated his core conviction: “Ethereum is the future of finance.”
Crucially, BitMine is not under immediate pressure to sell. Unlike many crypto treasury vehicles that rely on debt financing, the company funded its ETH purchases primarily through equity issuance, meaning it holds no debt covenants forcing a liquidation at any price. It also holds $538 million in cash and is generating income from staking more than 2.9 million ETH.
“There is no pressure to sell any ETH at these levels,” Lee said. “BitMine is in a position to ride out crypto volatility while earning recurring income and staking rewards.”
The compensation question
While BitMine’s balance sheet has taken a severe hit, a separate disclosure has raised eyebrows. A compensation package for Lee was approved by majority voting shareholders in January 2026, at a time when the company’s ETH treasury was already more than $4 billion underwater. The package is worth up to $95 million in cash over five years, with $15 million paid upfront and $20 million more in fixed payments across four years. An additional $60 million unlocks only if BitMine hits revenue targets escalating from $200 million in fiscal 2027 to $500 million in fiscal 2030.
Lee also received 1.5 million time-vesting restricted stock units and 4.5 million performance units tied to $125 and $250 share price targets, both far above current trading levels.
Buying through the pain
Despite the losses, BitMine has continued accumulating. The company added 45,759 ETH as recently as last week, pushing its total holdings to 5.28 million ETH. Lee described 2026 as a “defining year for Ethereum,” pointing to tokenisation, artificial intelligence integration, and Layer 2 adoption as the catalysts that will ultimately vindicate the strategy.
Whether that thesis plays out, or whether BitMine becomes a cautionary tale about concentrated ETH exposure at the wrong entry point, remains the central question hanging over one of the boldest institutional bets in crypto history.
