Bitmine, the Ethereum treasury company founded by Wall Street analyst Tom Lee, has accumulated 5.07 million ETH—representing 4.21% of total Ethereum supply—after purchasing 101,901 tokens in the week of April 20-27, 2026. The acquisition marks the company’s largest weekly buy since reaching the 5 million ETH milestone 10 months prior, even as unrealized losses on the portfolio hit $6.3 billion at current market prices.
Buying Into Underwater Positions
Bitmine’s average entry price across its holdings sits at $3,600 per ETH. Current market prices of $2,300 to $2,316 mean the company is nursing a 36% loss on its accumulated position. Despite this, the treasury firm has accelerated accumulation, purchasing 101,627 ETH in the prior week and continuing aggressive buying through late April. The Ethereum Foundation sold 10,000 ETH directly to Bitmine via over-the-counter transaction, adding institutional legitimacy to the company’s strategy. Lee has publicly called the 5 million ETH milestone “astonishing,” signaling conviction in the long-term thesis despite near-term headwinds.
Market Reaction and Stock Performance
BMNR, Bitmine’s stock ticker on traditional markets, gained 1% at Monday’s open but remains down 20% year-to-date, mirroring Ethereum’s own 20% decline over the same period. The stock trades at $22, reflecting investor skepticism about the company’s underwater position and capital allocation strategy. No material reaction from major exchanges has been reported, though the accumulation activity has drawn attention from on-chain analysts tracking large ETH transfers and treasury movements.
The Store-of-Value Thesis Under Pressure
Lee’s investment rationale centers on Ethereum as a strategic store of value, collateral asset, and infrastructure for AI agents operating on neutral blockchains. He has cited Ethereum’s outperformance versus the S&P 500 since the start of the US-Iran conflict as evidence of the asset’s macro utility. This positioning suggests Bitmine is building a long-duration bet on Ethereum adoption and institutional acceptance, betting that current prices represent a multi-year accumulation window. The company’s target is to hold 5% of total ETH supply, implying additional purchases ahead.
Financing the Drawdown
Critical details remain opaque: how Bitmine continues financing $230+ million in weekly purchases despite a $6.3 billion paper loss is not publicly disclosed. Whether the company relies on equity raises, debt, or operational cash flow remains unclear. The next critical variable is whether Bitmine reaches its 5% supply target or pauses accumulation if market conditions deteriorate further.
