Bitmine Adds $43 Million in Ether as Tom Lee Blames Crypto Weakness on Quarter-End Window Dressing

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.

As the world’s second-largest cryptocurrency, Ether attracts close scrutiny over the distribution of its supply and institutional positioning. Tom Lee’s investment firm BitMine has built a long-term position in digital assets. Changes in the size of its holdings reflect institutional confidence in the blockchain ecosystem, while its substantial share of Ether’s supply makes the company an important indicator of market liquidity and price volatility.

The latest data show that BitMine’s Ether holdings have increased to 5.77 million tokens, or about 4.8% of total supply. However, falling Ether prices weighed on related tokens and the broader market on Monday, July 13. Recent on-chain transactions involving institutions including Robinhood also put the cryptocurrency market under broad pressure on Monday.

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 Immersion Technologies launched its Ether treasury strategy in July 2025, raising funds through capital markets and steadily accumulating ETH to become the world’s largest publicly traded corporate holder. The model closely ties shareholder returns to Ether’s price and the company’s acquisition cost, making Bitmine an important test of whether corporate crypto treasuries can weather market cycles.

10x Research said on February 23, 2026, that ETH had fallen about 60% over six months and was trading below Bitmine’s average cost of $3,843 per token, leaving the company with a paper loss approaching $8.8 billion. Bitmine nevertheless bought another 45,749 ETH the previous week at an average price of $1,992. The research firm said current prices were testing whether the decline was a cyclical pullback or a deeper structural downturn.

Bitmine, led by Fundstrat co-founder Tom Lee, has adopted an “Ethereum MicroStrategy” strategy that makes Ether a core corporate reserve asset. Its long-term goal is to hold 5% of the circulating supply. The concentrated buying is affecting ETH supply and demand and reflects a new trend of listed companies using crypto assets to strengthen their balance sheets.

As of mid-July 2026, Bitmine had spent about $53 million to buy roughly 26,500 ETH in the previous week, well below its earlier pace of about 100,000 tokens per week. The company has bought more than 1 million ETH since the start of the year and now holds about 5.2 million, representing 4.31% of Ether’s circulating supply. Lee expects it to reach the 5% target by December.

Bit Digital, a company that has made crypto assets a core part of its corporate treasury, has continued accumulating Ether to expand its holdings. Its performance is closely tied to the price of ETH, making the timing of purchases and unrealized gains or losses key gauges of the company’s financial risk.

Bit Digital spent $20 million on about 8,568 ETH on May 11, its first addition since October last year, expanding its Ether treasury to roughly 158,000 ETH. ETH subsequently fell below $2,000, leaving the newly acquired position down about 15% and generating a paper loss of roughly $3 million.

Bitmine is an Ethereum treasury company whose core strategy is to hold ETH on its corporate balance sheet and steadily increase its exposure to the Ethereum ecosystem. Its holdings already exceed 4% of ETH’s total supply. Such large purchases reflect the institution’s view of the cryptocurrency’s price and could also affect market supply and demand as well as investor sentiment.

Bitmine bought 71,672 ETH last week as the cryptocurrency fell below $2,200, sharply increasing its purchases from the previous week. Its latest holdings surpassed 5.27 million ETH, or about 4.37% of total supply, closing in on its 5% target. Analyst Tom Lee called the pullback an attractive entry opportunity and said rising oil prices could weigh on cryptocurrency prices.

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.
