Bitmine appeared on the preliminary list for Russell 3000 inclusion, according to Chairman Tom Lee. Lee said BMNR would be added to the large cap Russell 1000 rather than the Russell 2000 because of the company’s market capitalization. Yahoo Finance data shows that Bitmine’s market cap currently stands near $11 billion, above the Russell 1000 threshold.

The potential Russell 1000 addition could make BMNR more visible to large cap equity managers and passive index products. Lee said many active managers only buy Russell 1000 equities and estimated that passive index funds and ETFs can hold 20% to 25% of the market cap of a stock included in the index.

FTSE Russell said 62 companies are expected to be added to the Russell 1000 at the end of the June 2026 reconstitution. The index provider will post updates after market close on May 29, June 5, June 12, and June 18, before the new indexes begin operating from the market open on June 29.

Bitmine said its crypto, cash, and moonshot holdings totaled $12.3 billion as of May 25. The company reported 5,390,404 ETH, 203 BTC, $444 million in cash, a $200 million stake in Beast Industries, and a $95 million stake in Eightco Holdings.

The company said its ETH holdings represent 4.47% of Ethereum’s 120.7 million token supply. Lee said Bitmine acquired 111,942 ETH over the past week and expects the company to reach its 5% ETH supply target sometime in 2026.

Bitmine also said 4,712,917 ETH, or more than 87% of its total ETH holdings, are now staked through MAVAN and its staking partners. Lee said the company’s staked ETH position could generate $276 million in annualized staking revenue based on a 2.75% seven day annualized yield.

Bitmine remains the world’s largest Ethereum treasury and the second largest global crypto treasury behind Strategy, which reportedly holds 818,869 BTC valued at $64.1 billion.
