Bitmine Immersion Technologies has expanded its Ethereum treasury to 5,700,040 ETH, strengthening its position as one of the largest publicly disclosed corporate holders of Ethereum. According to the company’s latest treasury update released on June 29, the firm’s combined crypto assets, cash, marketable securities and strategic investments are now valued at approximately $9.8 billion.
The latest figures indicate that Bitmine now owns roughly 4.7% of Ethereum’s estimated circulating supply of 120.7 million ETH, bringing the company close to its previously announced objective of accumulating 5% of the network’s supply. The update follows several weeks of continued Ethereum purchases and staking activity as the company expands its digital asset treasury.
Bitmine continued adding to its Ethereum reserves throughout June before deploying a significant portion of those assets into staking.
Recent treasury activity includes:
The company also disclosed that it acquired an additional 27,084 ETH over the past week, continuing what management described as a steady pace of accumulation throughout 2026. Chairman Thomas Lee said the company believes the cryptocurrency market remains in the early stages of a broader recovery and expects Bitmine to reach its long-term target of owning 5% of Ethereum’s circulating supply later this year.
The company said nearly 4.88 million ETH are now staked, representing approximately 86% of its treasury. Rather than maintaining idle reserves, Bitmine has increasingly allocated newly acquired Ethereum into validator infrastructure that generates staking rewards while supporting the Ethereum proof-of-stake network.
The latest treasury disclosure highlights how staking has become central to Bitmine’s digital asset strategy.
According to the company:
Institutional treasury managers have increasingly viewed staking as a way to generate recurring blockchain-based income while maintaining long-term exposure to Ethereum. However, staking also reduces liquidity because assets remain committed to validators while continuing to fluctuate with Ethereum’s market price.
Beyond its cryptocurrency holdings, Bitmine reached another milestone after joining the Russell 1000 Index on June 26 during the annual FTSE Russell index reconstitution.
Index inclusion may increase ownership by passive investment funds and ETFs that track Russell benchmarks. While membership does not directly affect Ethereum holdings, it can improve liquidity and broaden the company’s institutional shareholder base.
Earlier this month, Bitmine also completed its Series A Preferred Stock offering, raising approximately $274 million in net proceeds. The preferred shares now trade on the New York Stock Exchange under the ticker BMNP.
As of June 29, 2026, at 12:32 UTC, Ethereum traded at $1,586.35, up 9.87% over the previous seven days. The cryptocurrency’s market capitalization stood at approximately $191.44 billion, while 24-hour trading volume reached $8.43 billion.
ETH Chart
Although Ethereum’s short-term price continues to be driven primarily by broader market conditions, corporate treasury adoption has steadily increased over the past year. Companies holding Ethereum are increasingly combining reserve strategies with staking operations to generate additional yield from long-term holdings.
Bitmine’s latest treasury update underscores that trend. With nearly one-twentieth of Ethereum’s circulating supply now under its control, the company has become one of the most significant corporate participants in Ethereum’s proof-of-stake ecosystem, even as broader crypto markets continue to experience periods of volatility.
