Bitmine Boosts Ethereum Holdings With $81M ETH Purchase

Bitmine Immersion Technologies (BMNR), the world’s largest Ethereum treasury company, accelerated its ETH accumulation last week, purchasing 32,447 ether as cryptocurrency prices rebounded.

The latest Ethereum purchase is valued at roughly $81 million based on ETH trading near $2,500 on Monday. It increased Bitmine’s total holdings to 5,847,611 ETH, worth approximately $14.6 billion at current market prices.

BMNR shares gained about 3.5% in pre-market trading as Ethereum climbed above $2,500.

The Tom Lee-chaired company had slowed its Ethereum purchases in recent months as it approached its goal of controlling 5% of ETH’s circulating supply. However, Bitmine has continued adding ether every week since launching its Ethereum treasury strategy in June 2025.

Bitmine now owns roughly 4.8% of Ethereum’s estimated 120.7 million-token supply. Reaching its 5% target at the current supply level would require approximately 6.04 million ETH, putting the company about 187,000 tokens short.

The renewed buying activity comes as Ethereum records a strong market recovery. ETH gained roughly 30% over the past week, prompting Lee to suggest the cryptocurrency may have additional upside potential.

Lee pointed to previous occasions when Ethereum posted weekly gains exceeding 30%. ETH subsequently climbed 167% following a comparable move in July 2021 and 170% after a similar rally in May 2025. However, previous market performance does not guarantee future results.

Lee believes improving financial conditions, growing Wall Street interest in tokenizing real-world assets and potential blockchain adoption by artificial intelligence agents could strengthen Ethereum demand. He also expects these factors to help ETH outperform Bitcoin.

Meanwhile, Bitmine is generating income from its massive Ethereum treasury through staking. The company has staked approximately 5.07 million ETH, representing about 87% of its total holdings.

At current staking yields, Bitmine estimates its Ethereum position could generate roughly $330 million in annualized staking revenue, adding another potential source of returns as the company moves closer to its 5% ETH supply target.
