BitMine set to enter Russell 1000 with 5.673M ETH on its balance sheet

BitMine (BMNR) is slated to be added to the Russell 1000 Index on June 26, according to a report shared by Wu Blockchain, highlighting the growing presence of crypto-focused treasury strategies in public markets. The company said that as of June 22 it held about 5.673 million ETH, making it the largest publicly disclosed Ethereum treasury holder. BitMine's approach emphasizes active participation in Ethereum's proof-of-stake network rather than passive asset exposure. BitMine has staked roughly 4.88 million ETH, or about 86% of its total ETH reserves, with the staked amount valued at around $7.56 billion. On-chain data cited by Lookonchain indicated an additional staking move of 160,480 ETH, worth about $248.7 million, expanding the firm's footprint in Ethereum's validator ecosystem. The company estimates its annualized staking income at approximately $233 million, turning treasury assets into recurring yield. Ethereum was trading around $1,559.24 at the time of writing, down 5.30% over 24 hours and 8.02% over the past seven days. On the balance sheet, BitMine reported $601 million in cash and marketable securities and $350 million in preferred BMNP securities, and said it carries no debt. The debt-free structure differentiates it from earlier crypto treasury models that relied more heavily on leverage. Inclusion in the Russell 1000 can raise institutional visibility as index-tracking funds adjust holdings after reconstitutions, a process that often supports liquidity and broadens the shareholder base. BitMine's expansion also underscores how corporate crypto treasuries are evolving beyond bitcoin accumulation, with Ethereum offering embedded yield through staking alongside price exposure.
