Bitmine sits on $8.9B in unrealized ETH losses as ether…

Bitmine Immersion Technologies (BMNR), the largest corporate holder of ether, is staring at an estimated $8.9 billion in unrealized losses after ETH broke below $1,800 — revisiting the lows last seen in February's selloff. Shares of the Tom Lee-chaired company fell another 5.9% Wednesday, slipping below $17 and extending their decline to 28% since early May, now trading at their weakest level since the company announced its Ethereum treasury pivot in May 2025.

Why it matters

Bitmine has amassed more than 5.4 million ETH — roughly 4.5% of Ethereum's circulating supply — in under a year, financed primarily through equity issuance rather than debt. That structure avoids the leverage and interest-payment risk that haunts some treasury peers, and the company generates roughly $276 million in annualized staking revenue from the 4.7 million ETH it has staked via its MAVAN service. But those buffers haven't insulated the stock from the broader pressure crushing digital asset treasury names: ETH is down more than 20% since early May, when Lee publicly declared the market's "mini crypto winter" had ended and "crypto spring" had begun. Strategy's recent disclosure of its first bitcoin sale since 2022 has added to sector-wide anxiety about the sustainability of the treasury-accumulation playbook.

Market impact

With ETH back near February lows and Bitmine's $10 billion position now $8.9 billion underwater, the gap between Lee's long-term thesis — he called for a $250,000 ETH price at the Proof of Talk conference in Paris this week — and the market's current reality is impossible to ignore. Investors are pricing the near-term, not the tokenization and AI-driven demand narrative Lee is selling.
