Bitmine Immersion, a major player in Ethereum treasury management, has made headlines following a significant purchase last week. Company president Tom Lee shared that Bitmine acquired a total of 111,942 ether (ETH), valued at around $237 million according to current market prices.
New wave of ETH acquisitions
With this latest move, Bitmine completed its largest ETH transfer since December. The company’s total ether holdings have now reached approximately 5.4 million ETH, representing 4.47% of Ethereum’s entire circulating supply. Although Bitmine announced in May it would slow its weekly purchases, the recent drop in ETH prices appears to have prompted the company to accelerate its buying pace once again.
“We continue to steadily add ETH to our portfolio. The pullback below $2,200 recently offered an attractive opportunity for us,” explained Tom Lee, president of Bitmine, in reference to the company’s strategy.
Speaking at the Consensus 2026 conference in Miami, Tom Lee underlined Bitmine’s goal of increasing its market share in the near term.
5% market share ambition
Bitmine aims to reach 5% of Ethereum’s total supply within the next year at its current pace. With its latest purchase, the company’s market dominance has further strengthened. Recent reports indicate that Bitmine holds total crypto and cash assets valued at $12.3 billion. Its portfolio also includes 203 bitcoin and $444 million in cash and equity investments, along with stakes in innovative technology firms.
Glossary: Staking is a practice where investors lock up their cryptocurrency to support the network’s security and, in return, earn rewards. This is especially common for “proof-of-stake” networks like Ethereum.
Growth in staking revenue
Approximately 4.7 million of Bitmine’s ETH holdings—about 87% of its portfolio—are allocated to staking. The company generates roughly $276 million in annual income from this activity. Staking allows Bitmine to both earn steady passive returns and contribute to the Ethereum blockchain ecosystem.
