BitMine Immersion Technologies is within roughly 187,000 ETH of owning 5% of Ethereum’s total supply after building a treasury of 5,847,611 ETH worth about $14.3 billion as of Aug. 24. At its recently disclosed weekly purchase pace of 32,447 ETH, the NYSE-listed company would reach its 6.04 million ETH target in about six weeks, assuming supply and buying rates remain broadly unchanged.
The final purchases would cost about $460 million at the ETH prices used in BitMine’s disclosure. The company’s holdings represented 4.84% of Ethereum’s approximately 120.7 million ETH supply, placing its treasury among the largest concentrated positions in the network’s native asset.
BitMine’s rapid accumulation has turned a former crypto-mining equipment business into a public-market vehicle built around Ethereum exposure and staking income. Its chairman, Tom Lee, took the role as the company redirected its balance-sheet strategy toward ETH, beginning the treasury program on June 30, 2025.
From mining equipment to an Ethereum treasury
Before the strategy change, BitMine focused on immersion-cooling equipment for cryptocurrency miners. Immersion systems place computing hardware in specialized liquid to manage heat, an approach used by some operators running energy-intensive mining fleets.
The company’s business model changed sharply after Lee joined in early 2025. Rather than primarily selling mining-related hardware, BitMine began issuing securities and using proceeds to acquire ETH. It has reported ETH purchases every week since launching the program, according to the information provided.
The buying campaign crossed 1% of Ethereum’s supply in August 2025 and 2% a month later. In September 2025, BitMine raised $365 million through a stock issuance priced at $70 per share.
Its ETH holdings rose above 4.66 million in March 2026 and exceeded 5.20 million in May. The pace gives the company an unusually large role in the market for a publicly traded corporation, while also tying its financial results more closely to Ethereum’s price and staking conditions.
BitMine added to its funding capacity in June 2026 with a $274 million preferred-stock issue. The security, trading under the ticker BMNP, was priced at $80 per share and carries a 9.5% annual coupon. The company identified ARK Invest, Founders Fund, Pantera Capital and Galaxy Digital among the participants.
The preferred dividend creates a fixed cash obligation that differs from the variable rewards BitMine earns from staking ETH. BitMine cited a 2.61% seven-day annualized staking yield, below the preferred stock’s 9.5% coupon rate. The company has also reported an unrealized loss figure of $9.1 billion related to the relationship between ETH market prices and its acquisition basis.
More than $12 billion of ETH is staked
BitMine has placed most of its ETH treasury into Ethereum’s staking system. As of Aug. 23, it reported 5,067,309 staked ETH, equal to about 87% of its ETH holdings and valued at approximately $12.4 billion.
Using BitMine’s stated 2.61% annualized yield, that staked balance would generate about $287 million in annualized staking rewards if the rate and staking amount held steady. Such rewards are paid in ETH, so their dollar value would move with the asset’s market price.
The company has developed a staking platform called MAVAN for internal operations and has said it intends to make the system available to institutional clients and custodians. That plan could give BitMine a service business alongside the ETH treasury, though its current financial profile remains dominated by the value and performance of its token holdings.
Ethereum had about 42 million ETH staked across the network, or roughly 34% of supply, based on the figures provided. BitMine’s 5.07 million staked ETH would therefore account for about 12% of all ETH committed to validators.
Lido, the largest liquid-staking provider, held about 8.83 million staked ETH, or 20.9% of the staking market. BitMine’s staked balance was about 57% of Lido’s reported total, illustrating how quickly a single corporate treasury has approached the scale of Ethereum’s largest staking organizations.
Concentration brings operational scrutiny
Large ETH ownership does not give BitMine direct authority over Ethereum upgrades. The network does not use token-weighted on-chain voting for governance; protocol changes move through Ethereum Improvement Proposals, developer discussions and coordination among client teams, researchers, node operators, application builders and the wider community.
Staking concentration raises a different set of questions. Validators participate in block production and transaction processing, meaning the behavior of a large staking operator can affect network resilience and censorship resistance. The company’s status as a U.S.-listed entity may also draw attention to how it would respond if compliance requirements affected validator operations.
Past U.S. sanctions actions, including the Office of Foreign Assets Control’s designation of Tornado Cash, have shown how legal restrictions can create difficult choices for entities involved in transaction processing. No specific requirement affecting BitMine’s validators was identified in the supplied information.
The issue has already become part of public debate among major staking participants. In August 2026, Lido publicly disagreed with Ethereum core developers over EIP-8363, a proposal related to staking returns. The dispute showed that large staking providers can become influential voices in technical and economic discussions even without formal governance control.
Asset mix extends beyond ETH
BitMine placed its total assets at about $14.9 billion. In addition to ETH, the company disclosed 210 bitcoin, $180 million of equity in Beast Industries, $89 million of equity in Eightco Holdings, which trades on Nasdaq as ORBS, and roughly $308 million in cash and marketable securities.
It described the Beast Industries and Eightco positions as “moonshot” investments, separating them from the core ETH treasury. BitMine was also added to the Russell 1000 Index on June 26, 2026, bringing the shares into an index tracked by some large fund products.
Lee said on Aug. 24 that ETH had risen 30% over the preceding week, which he described as the asset’s largest weekly increase since May 2025. BitMine’s near-term path to 5% now depends mainly on whether it maintains its disclosed purchasing cadence and continues to access capital without substantially changing the financing structure behind its Ethereum strategy.
