Bitmine Immersion Technologies (BMNR) has landed on the preliminary additions list for the 2026 Russell 3000 Index, marking a milestone moment for a company that has aggressively repositioned itself as the world’s largest Ethereum treasury holder.
FTSE Russell published the preliminary list on May 22-23, with a final decision on inclusion expected by the end of June 2026. If confirmed, BMNR would join an index tracked by trillions in passive investment capital, effectively forcing index funds and ETFs to buy shares of a company whose core thesis is holding enormous amounts of ETH.
From mining rigs to Ethereum vaults
Bitmine’s trajectory reads like a crypto pivot playbook on fast-forward. Originally incorporated in 2019 as Sandy Springs Holdings, the Las Vegas-based company transformed into an Ethereum treasury management and blockchain ecosystem services firm. The company now claims to hold over 5 million ETH, roughly 4% of Ethereum’s total supply, while maintaining smaller Bitcoin positions on the side.
The stock’s 52-week range tells that story plainly. BMNR shares have traded between $3.92 and $161.00, with daily trading volumes that reportedly reach into the billions of dollars.
The company also operates MAVAN, an Ethereum staking platform, which adds a yield-generating layer to its treasury strategy. Rather than simply sitting on ETH and hoping for price appreciation, Bitmine earns staking rewards on its holdings, creating a recurring revenue stream tied directly to Ethereum’s proof-of-stake consensus mechanism.
The Russell 3000 effect
BMNR’s uplisting to the NYSE in April 2026 likely played a role in meeting the eligibility criteria for index consideration. The move from smaller exchanges to the New York Stock Exchange signaled operational maturity and satisfied the kind of listing standards that index providers care about deeply.
The company’s chairman, Tom Lee, brings additional institutional credibility to the table. Lee is best known as co-founder of Fundstrat Global Advisors, where he built a reputation as one of Wall Street’s more visible and consistently bullish voices on both equities and digital assets.
The firm has also been running share repurchase programs, which signal management’s confidence in the stock’s value and help support the price by reducing the float.
What this means for investors
The investment case for BMNR is inseparable from the investment case for Ethereum. A company holding 4% of an asset’s total supply is, for all practical purposes, a concentrated bet on that asset with corporate overhead attached. If ETH rallies, BMNR likely outperforms on a percentage basis due to leverage and operational income from staking. If ETH drops significantly, the math works in reverse, and that 52-week low of $3.92 is a reminder of how quickly things can unwind.
MicroStrategy pioneered the Bitcoin treasury model and eventually landed in the S&P 500. Bitmine is attempting the Ethereum equivalent, and the Russell 3000 nod suggests the market is at least willing to entertain the thesis.
BMNR’s 5 million ETH position gives it a first-mover scale advantage, and the staking operation through MAVAN adds a dimension that pure treasury plays don’t have, generating yield that can fund operations or be reinvested into additional ETH purchases.
