BitMine Immersion Technologies
NYSE American: BMNRBitMine used to cool mining rigs with immersion tanks. Now Tom Lee has it chasing 5% of the entire Ethereum supply.

Who they are
BitMine Immersion Technologies began as a small bitcoin mining company using immersion-cooling technology to boost hashrate efficiency. In mid-2025 it pivoted dramatically under Chairman Tom Lee — the well-known Wall Street strategist behind Fundstrat — into what has become, by a wide margin, the largest corporate holder of Ethereum in the world.
BitMine’s ambition, stated explicitly, is to accumulate 5% of Ethereum’s entire circulating supply — a target Lee calls the “Alchemy of 5%.” As of mid-2026 the company was closing in on that goal, holding well over 5.5 million ETH.
What they actually do
Accumulate Ethereum, aggressively and continuously. Weekly purchase updates have become something of a company ritual, with BitMine regularly adding tens of thousands of ETH funded through equity raises and preferred stock offerings.
Stake nearly all of its ETH for yield. Unlike a passive spot holding, BitMine runs its own institutional staking infrastructure — the Made in America Validator Network (MAVAN) — to generate ongoing staking rewards, projected at hundreds of millions of dollars annually once fully deployed. This gives BitMine’s ETH treasury a productive income stream that a simple buy-and-hold position wouldn’t have.
Diversify at the margins into “moonshot” stakes. BitMine has taken smaller equity positions in companies like Beast Industries and Eightco Holdings (which itself holds OpenAI equity), giving shareholders incidental exposure well beyond crypto.
How they make money
Ethereum price appreciation on its treasury, plus meaningful ongoing staking-reward income from its MAVAN validator network — a genuine second revenue stream that distinguishes BitMine from pure buy-and-hold treasury peers.
Where it sits in the value chain
The bigger trend it’s riding
BitMine represents the Ethereum-flavored branch of the same digital asset treasury wave that Strategy started for bitcoin — but with a meaningful structural twist. Because Ethereum uses proof-of-stake, an ETH treasury can generate real, ongoing yield simply by staking, something a bitcoin treasury structurally cannot do. Tom Lee has framed this as a “sovereign put” thesis: a large, staked ETH treasury becomes strategically valuable enough that institutions or even governments needing large ETH positions would rather deal with BitMine than buy on the open market.
What to watch (not what to do)
What to watch (not what to do)
- Ethereum price volatility. BitMine's holdings have swung by billions of dollars in unrealized gains and losses within single quarters, since the treasury is heavily concentrated in one asset.
- Pace of accumulation versus the 5% target. Lee has both accelerated and deliberately slowed purchases at different points to avoid moving the market too aggressively — watch how close BitMine gets to its stated goal and how that's funded.
- Staking yield realized versus projected. BitMine regularly cites the annualized staking reward if 100% of its ETH were staked at scale — actual realized income depends on staking participation rates and network yield, both of which move over time.
