BitMine Immersion Technologies bought 32,977 Ethereum (ETH) in a move that grabbed investor attention and pushed its stock higher. The purchase was reported to be part of the company’s recent accumulation of crypto assets during the final week of 2025. BMNR shares rallied as traders reacted to the disclosure, with early session gains seen on US exchanges.

According to a press release, BitMine now holds about 4.143 million ETH on its balance sheet. That amount was given as roughly 3.43% of the circulating supply, a large stake for a publicly traded miner.

The company’s total crypto, cash, and strategic investments were reported at about $14.2 billion. The fresh buy of 32,977 Ether adds scale to a position that is already substantial and has been built up over several months.

Roughly 659,219 ETH in BitMine’s portfolio is currently staked. That portion is being used to generate yield while the firm holds the rest in custody, reports said. Company plans that were disclosed include expanding its validator operations under a program named the Made In America Validator Network, an initiative the firm expects to push forward in early 2026. The staking figure and the new purchase together show BitMine is balancing liquid holdings with income-producing assets.

Market moves were quick. BMNR saw notable trading volume after the announcement, and pre-market figures showed gains around 4% in some sessions. Traders and institutional desks flagged the purchase as a reason for higher demand in the stock, while others said the move simply confirms that large players still see value in holding ETH.

The firm is also set to hold its Annual Stockholder Meeting on January 15, 2026, where proposals including an increase in authorized shares will be put to a vote. That meeting adds a corporate governance angle to the market story, since shareholders will weigh both the crypto strategy and broader capital plans.

Analysts say the next signals to watch are: daily flow in ETH markets, any fresh disclosures from BitMine about further buys, and volume patterns in BMNR trading. Reports indicate the company has been one of the larger active ETH buyers recently, and continued accumulation could keep interest alive among investors.

Price action in both ETH and BMNR will likely drive headlines over the coming weeks as markets digest the full impact of the new holdings.
