Tom Lee and BitMine Close In on Massive Ethereum Buy in Bold Institutional Signal

BitMine Immersion Technologies added 101,627 ETH worth approximately $235 million last week – its largest single-week purchase since December – pushing total holdings to 4,976,485 ETH valued at more than $11.5 billion.

Ethereum was trading at $2,312 at the time of the update, down 1.1% in the prior 24 hours but up 5.4% over the week, sitting roughly 53% below its August all-time high of $4,946. The purchase puts BitMine on the immediate edge of crossing the 5 million ETH threshold, a milestone that would cement its position as the dominant institutional ETH holder on the planet.

Tom Lee (BitMine chairman and former Fundstrat Global Advisors strategist) framed the accumulation in explicitly bullish terms. “While many believe the crypto winter may last through the fall of 2026, our view remains that the crypto winter is much closer to ending,” Lee stated in the company’s Monday update. He attributed Ethereum’s recent recovery to easing geopolitical pressure, noting that ETH has risen 41% from its early February lows as downside risks tied to the U.S.-Iran conflict have diminished.

BitMine Treasury Strategy and What It Signals for Ethereum

BitMine now controls more than 4.1% of the entire ETH circulating supply – a concentration that makes the firm a structurally significant participant in the asset’s price discovery. The company also holds 199 Bitcoin (approximately $15 million) and $1.12 billion in cash as of Monday’s update, but Ethereum is clearly the firm’s primary conviction trade. At current holdings, BitMine ranks second among publicly traded companies by crypto treasury value, trailing only Strategy’s $61.4 billion Bitcoin stockpile.

Lee’s positioning goes beyond simple accumulation. BitMine actively stakes approximately 68% of its ETH holdings, generating an estimated $172 million annually in staking rewards – a yield layer that partially offsets the accounting headwinds the firm is carrying. The company has also deployed ETH as collateral in DeFi protocols, including Aave, suggesting a sophisticated treasury management approach rather than passive holding.

The unrealized loss picture is substantial: BitMine reported a net loss of $3.8 billion for the three-month period ending February 28, with 99% attributed to paper losses on ETH as the asset slid from its $4,946 August peak. Over the six-month period ending the same date, total reported losses exceeded $9 billion. Those figures have weighed heavily on BMNR shares, which are trading at $22.21 – 86% off their 52-week high of $161 and down nearly 59% over six months. Yet BitMine’s response to that drawdown has been to buy more ETH, not less. That conviction buying – especially at this scale – carries a signal independent of the share price.

Lee has publicly framed Ethereum as the premier wartime store of value, stating that “there is a lot of meaning to ETH being the best ‘war-time store of value,’ and to ETH being the asset leading since the war started.” Whether that thesis proves correct, the institutional commitment behind it is now measured in billions of dollars and millions of ETH.
