BitMine Immersion Technologies said it increased its ether treasury to 5,901,112 ETH after buying 53,501 ETH during the previous week, lifting its holdings to roughly 4.9% of Ethereum’s reported 120.7 million-token supply. At an ether price of $2,511, the company valued the position at about $14.8 billion in its Monday announcement.
The disclosure places BitMine among the largest known corporate holders of ETH and further concentrates a sizeable portion of its balance sheet in Ethereum’s native asset. The company reported total crypto, cash and other assets of $15.6 billion as of Aug. 30, meaning ether accounts for the overwhelming majority of the reported portfolio.
Chairman Tom Lee said ether outperformed the S&P 500 by 5,430 basis points, or 54.3 percentage points, in the third quarter through Aug. 28. He also named ETH, Bitcoin and Solana as the three best-performing assets since June 30, although the company did not provide comparative return figures for each asset in the announcement.
Ether traded above $2,400 on Monday after a relatively subdued session, according to the supplied market update. BitMine shares had closed down 7.14% at $23.80 on Friday before recovering modestly above $24 in Monday morning trading. The divergence illustrates a familiar feature of digital-asset treasury companies: their shares can react not only to movements in the underlying token but also to changes in how public-market traders value the company’s structure, financing and operating strategy.
Most of BitMine’s ether is now staked
BitMine said 5,067,309 ETH, representing about 86% of its ether balance, had been staked through its MAVAN platform and external staking partners. Using the company’s stated seven-day annualized staking yield of 2.63%, it projected annualized staking revenue of about $335 million.
Staking involves committing ETH to Ethereum’s proof-of-stake network, helping validate transactions and secure the chain in exchange for protocol rewards. For BitMine, the arrangement turns a large passive treasury position into an income-producing asset, while also reducing the amount of ETH it holds in immediately liquid form.
The reported $335 million figure is a yield-based estimate rather than a fixed payment. Staking returns can change with network conditions, validator performance, fee activity and the amount of ETH already committed to staking. The dollar value of any rewards would also rise or fall alongside ETH’s market price.
BitMine’s strategy therefore depends on two connected assumptions: that ETH will retain or increase its value over time, and that the staking income can offset some of the carrying costs and volatility associated with holding a multi-billion-dollar token reserve. The company’s decision to stake most of its balance suggests it is positioning the treasury as a long-duration allocation rather than maintaining a large pool of ETH for frequent trading.
Treasury includes Bitcoin, equity stakes and cash
Beyond ether, BitMine reported holding 211 Bitcoin, an $180 million stake in Beast Industries and an $81 million stake in Eightco Holdings. It also listed $541 million in cash and marketable securities.
Those non-ETH assets amount to a comparatively small share of the company’s disclosed $15.6 billion asset total, leaving BitMine’s financial profile closely tied to Ethereum. A sustained decline in ETH would affect both the reported value of its treasury and the dollar value of staking rewards, while a rise would have the opposite effect.
The company’s scale also means its purchases and staking decisions will be watched closely by Ethereum market participants. Acquiring 53,501 ETH in one week is meaningful in corporate-treasury terms, but the announcement alone does not establish where purchases occurred, whether they were executed through over-the-counter channels, or how they affected exchange liquidity. Claims that BitMine’s buying will automatically force ETH prices higher go beyond the information available.
Large holdings can influence the available float if tokens are moved into long-term custody or staking, yet market pricing also depends on demand across spot and derivatives markets, macroeconomic conditions, network activity and sales from other holders. Staked ETH is subject to withdrawal processes, so it should not be treated as permanently removed from potential market supply.
A concentrated corporate wager on Ethereum
BitMine’s reported 4.9% share of Ethereum’s supply makes its treasury substantially different from a conventional corporate crypto allocation. The company is building an ownership position large enough for its staking operations to become a material source of reported revenue, assuming its yield projections hold.
That structure gives public-market traders a route to gain exposure to a large ETH position through BitMine’s shares, although the stock is not a direct substitute for owning ether. The company also carries operational risks related to custody, staking counterparties, corporate financing, equity-market valuation and the management of its other assets.
Lee’s performance comparison with the S&P 500 frames the treasury strategy around ETH’s strong quarter-to-date return through late August. The more durable test will be whether staking income, balance-sheet management and the company’s share price can remain resilient when Ethereum’s price cycle turns less favorable.
For now, BitMine’s latest purchase extends a strategy built around scale: accumulate ether, stake most of it, and use the resulting yield to support a corporate treasury centered almost entirely on Ethereum.
