BitMine is set to enter the Russell 1000 on June 26, a move that comes as the company disclosed holdings of about 5.673 million ETH as of June 22. That disclosure places BitMine at the top of publicly reported corporate Ethereum treasury holders and puts fresh attention on Ethereum-based treasury strategies in public markets.
A report cited by Wu Blockchain said the index inclusion marks a notable step for listed digital-asset treasury firms. For companies added to major benchmarks, passive funds often rebalance their portfolios to reflect index changes. That process can affect share turnover and broaden the investor base for BMNR.
Most of the ETH reserve is already staked
BitMine is not holding Ethereum as a passive reserve. The company said roughly 4.88 million ETH has been staked across its treasury, equal to about 86% of total holdings. Based on the disclosed figures, the staked portion is valued at around $7.56 billion.
On-chain data shared by Lookonchain also showed another sizable move: BitMine staked an additional 160,480 ETH, worth about $248.7 million. That transaction expanded its footprint in Ethereum’s validator network and reinforced a treasury model built on yield generation rather than simple balance-sheet exposure.
Staking income and a debt-free balance sheet stand out
Company disclosures estimate annualized staking income at about $233 million. In practice, that turns treasury assets into capital producing recurring returns instead of remaining idle on the balance sheet. Compared with earlier corporate crypto treasury models centered on Bitcoin accumulation, Ethereum introduces a native income layer through staking.
BitMine also reported $601 million in cash and marketable securities, along with $350 million in preferred BMNP securities. The company said it has no outstanding debt. That debt-free position separates it from some earlier crypto treasury structures and lowers exposure tied to financing obligations.
Public markets are giving Ethereum treasury models closer scrutiny
BitMine’s expansion points to a broader shift in how institutions assess digital assets as treasury reserves. In earlier market cycles, the corporate focus was largely on Bitcoin. Ethereum changes that framework because the asset can be held while also generating on-chain yield through staking infrastructure.
At the time referenced in the report, ETH was trading at about $1,559.24. The token was down 5.30% over 24 hours and 8.02% over the previous seven days. Even with that price decline, BitMine continued adding to its staked position, showing that its treasury approach is tied to reserve deployment and staking income as much as market price exposure.
