Bitmine Immersion Technologies is within striking distance of a goal that sounded almost absurd when it was first announced: owning 5% of all circulating Ethereum. The NYSE-listed company (ticker: BMNR) currently holds between 5.54 million and 5.77 million ETH, representing approximately 4.59% to 4.78% of the estimated 120.7 million ETH in circulation. That leaves roughly 507,000 ETH between Bitmine and its target of 6.035 million ETH.
From Bitcoin mining to Ethereum treasury
Bitmine’s journey here is one of the more dramatic corporate pivots in recent crypto history. The company originally focused on Bitcoin mining, and at some point leadership decided the better play was accumulating ETH as a primary reserve asset rather than mining BTC.
Chairman Tom Lee has been the architect of what the company calls the “alchemy of 5%.” The underlying strategy is straightforward: buy a lot of Ethereum, then buy more, then stake it for yield while continuing to buy.
The company’s total crypto and cash holdings now sit between $9.6 billion and $11.3 billion. Bitmine’s stock has become one of the most actively traded equities in the US market, with daily volumes reaching into the hundreds of millions and sometimes billions of shares.
The institutional backing tells a story
The company has attracted institutional backing from ARK Invest, led by Cathie Wood, alongside Founders Fund and Pantera Capital.
Staking as an income engine
In 2026, the company launched its Made-in-America Validator Network, or MAVAN, a staking infrastructure designed to generate yield on its holdings. The reported 7-day staking yield sits at 2.99%, which on a base of roughly 5.5 million ETH translates to a meaningful income stream.
What this means for investors and the ETH market
Chairman Tom Lee has indicated that Bitmine plans to moderate its purchasing pace as it approaches the 5% threshold. For the broader Ethereum market, Bitmine’s accumulation raises questions about supply concentration: when a single corporate entity holds nearly 5% of a network’s circulating supply, a locked-up, staked treasury of that size effectively removes a substantial portion of supply from active circulation. If ETH’s price drops significantly, the staking yield provides some cushion, but 2.99% doesn’t fix a 40% drawdown.
Investors watching BMNR should pay close attention to the pace of remaining purchases, any changes in staking yield as the validator network scales, and whether the institutional backers maintain or increase their positions as Bitmine closes in on its target.
