Bitmine Immersion Technologies appeared on the preliminary additions list published by FTSE Russell on 18 Jun. The Russell 1000 – which tracks the largest US-listed companies by market capitalisation – sits within the broader Russell 3000 universe, and the company says its market cap qualifies it for the large-cap tier. The reconstitution becomes effective after US markets close on 26 Jun. Final index membership has not yet been confirmed.
Bitmine is a publicly listed Ethereum treasury company that uses capital markets financing and staking to build a large Ether ($ETH) balance sheet. The company said on 22 Jun that it held 5.67mn $ETH, equal to 4.7% of the token’s total supply.
Index inclusion matters because many exchange-traded funds (ETFs), mutual funds and institutional mandates track or reference benchmarks such as the Russell 1000. When a company enters an index, passive funds that replicate that benchmark may need to buy its shares, creating baseline demand that can help support prices.
Crypto moves into benchmarks
For crypto-linked companies, index membership has become a marker of institutional acceptance. Strategy’s entry into the Nasdaq 100 in December 2024 brought a bitcoin treasury company into one of the most closely followed US growth benchmarks. Coinbase joined the S&P 500 in May 2025, becoming the first crypto-native company in that index.
Those events did not change the underlying businesses, but they did change who had to pay attention to them. Index membership can increase liquidity, broaden ownership and embed crypto exposure inside ordinary equity portfolios.
Bitmine would represent a different version of that trend. The company is not an exchange such as Coinbase or a bitcoin treasury such as Strategy, and has built its market identity entirely around Ether accumulation and staking.
The company says it is close to its goal of owning 5% of all $ETH. It also reported total crypto, cash, marketable securities and other holdings of $10.7bn.
Institutional flows in focus
Tom Lee, Bitmine’s chair and head of research at Fundstrat and FS Insight, has said Russell inclusion could matter because large passive and active pools use the index as a reference point.
But the tailwind effect of index inclusion is not guaranteed. It can be offset by valuation, market sentiment or weakness in the underlying asset. Bitmine’s shares remain tied to Ether’s price, its staking income and investor confidence in its treasury model.
A confirmed Russell 1000 entry would place Bitmine beside major US equities and extend crypto’s presence in standard institutional allocation channels.
