Bitmine Expands Ether Holdings, Cementing Lead as World’s Largest Corporate Holder

Bitmine has emerged as one of the largest corporate holders of ether, using its balance sheet to pursue a digital-asset treasury strategy under Chairman Tom Lee. The company now controls about 4.9% of Ethereum’s supply, making its purchases a closely watched gauge of institutional demand. Its growing position also underscores the increasing concentration of ETH in corporate treasuries as public companies seek leveraged exposure to cryptocurrency prices.

Bitmine added nearly 10,000 ETH last week, lifting its holdings to about 5.79 million tokens. In an earlier weekly purchase, the company spent $131 million on 53,501 ETH, its largest acquisition since June. Lee said the ETH/BTC ratio had reached a three-month high while ether outperformed bitcoin, signals he views as evidence of strengthening market momentum. Bitmine shares also surged 43% over the past month as investor interest in crypto-linked equities increased.

Bitmine Immersion Technologies, chaired by Tom Lee, has purchased ether every week since launching its ETH treasury strategy on June 30, 2025. The company is pursuing its “Alchemy of 5%” target, seeking to control 5% of Ethereum’s supply. With total crypto and cash holdings of about $11.5 billion and roughly 85% of its ETH staked for yield, the share repurchases mark a shift toward balancing treasury expansion with returns to shareholders.

On July 20, Bitmine said it added just 7,430 ETH, worth about $14 million, during the prior week, lifting its holdings to 5,777,468 ETH. It simultaneously spent about $86 million to repurchase 5.5 million shares at an average $15.62 each. A July 27 update showed purchases recovering to 9,946 ETH, taking the treasury to 5,787,414 ETH, while weekly buybacks rose to 6.1 million shares and cumulative repurchases reached 11.6 million.

As the largest corporate holder of Ether, BitMine Immersion continues to treat the cryptocurrency as a key reserve asset and is actively pursuing its goal of owning 5% of the circulating supply in 2026. Chairman Tom Lee said market expectations of a significantly greater chance that the U.S. Clarity Act will pass have helped drive the recent rise in Ether’s price. Greater policy clarity is also prompting companies and users to increasingly treat Ether as real money, laying the foundation for long-term growth.

According to the latest developments in July 2026, BitMine Immersion bought another 42,197 Ether last week, worth about $74 million, bringing its total holdings to 4.8% of the circulating supply. Lee confirmed that the accumulation included heavy buying within a 24-hour period, followed by a further purchase of 27,000 Ether as the company seeks to achieve its strategic “Alchemy of 5%” ownership target by year-end.

Bitmine, the world's largest corporate holder of ether, continues to use company funds to build its ETH reserve, with the market watching how its large purchases affect supply and prices. As its holdings approach 5% of Ethereum's total circulating supply, the company has become an important gauge of institutional crypto adoption.

Bitmine recently spent about $43 million to acquire another 27,084 ETH, further increasing its total holdings. Chairman Tom Lee said the recent weakness in cryptocurrencies was primarily driven by quarter-end "window dressing" in late June, as investors exited impaired positions before the second half began, creating short-term selling pressure.

BitMine has made Ethereum (ETH) its primary treasury asset, using continued purchases and staking to build the world’s largest Ethereum treasury. Its long-term goal is to hold close to 5% of ETH’s circulating supply. Chief Executive Tom Lee believes the Ethereum network’s applications and yield-generating capacity remain supportive, and that short-term price volatility does not alter the company’s strategy.

In the week through July 19, 2026, BitMine deployed about $92 million during a market decline to buy an additional 127,000 ETH, raising its total holdings to 5.54 million ETH. About 4.72 million ETH had been staked to earn an annualized yield. Lee described the recent selling pressure as a “surface phenomenon” unrelated to fundamentals.

Bitmine is adapting the corporate Bitcoin accumulation strategy by making Ether its core reserve asset, with a target of holding 5% of the circulating supply. Chairman Tom Lee sees Wall Street’s push into asset tokenization and AI agents’ adoption of blockchain payments as the twin engines of the next crypto supercycle.

As of July 2026, Bitmine had added 112,000 ETH over the latest week at less than $2,200 per token, in purchases worth up to about $246 million, lifting its total holdings to 5.4 million ETH. Its latest purchase alone was worth another $52 million. Lee said Ether’s price had yet to reflect strengthening fundamentals, even as Bitcoin ETFs suffered outflows.

BitMine Immersion Technologies has amassed Ether on its corporate balance sheet, aiming to control 5% of the global circulating supply while generating yield through staking. The strategy has made it the world’s largest corporate holder of ETH, while closely tying its valuation to the token’s price, regulatory developments and the risks of concentrated ownership.

BitMine said on March 23, 2026, that its total assets had reached $11 billion and that it held 4,660,903 ETH, equal to 3.86% of supply. It added 65,341 tokens worth about $138 million in one week. Holdings had exceeded 5.18 million tokens by May 7. Chairman Tom Lee said the company would slow its purchases as it approached the 5% target and viewed the CLARITY Act as a positive catalyst.

Bitmine Immersion Technologies is pursuing an “Ethereum MicroStrategy” treasury strategy, using corporate assets to acquire Ether as it seeks to raise its holdings to 5% of total supply. The scale of the position tightly links the company's share price and financing capacity to Ether's supply and demand, drawing attention to its move to the New York Stock Exchange's main market.

Bitmine most recently reported holdings of 4.8 million ETH, equivalent to about 3.98% of total supply, and approximately $11.8 billion in crypto assets. It bought another 71,000 ETH in one week, its largest increase since December 2025. The company also uplisted to the NYSE, increased its share-repurchase authorization to $4 billion and staked more than 3.33 million ETH through the Mavan network, with estimated annualized returns of $196 million.

BitMine Immersion Technologies is a publicly listed U.S. digital-asset treasury company whose core strategy is to accumulate ETH over the long term, with a target of holding 5% of Ethereum’s total supply. Its latest indirect investment in privately held OpenAI through Eightco shows that the company is deploying capital across two major growth themes: blockchain and artificial intelligence.

BitMine said on March 16, 2026, that it had added 60,999 ETH in the week through March 15, raising its total holdings to 4,595,562 ETH, or 3.81% of total supply. Of that amount, 3,040,515 ETH had been staked. The company also invested an additional $80 million in Eightco to support its $50 million acquisition of OpenAI equity.
