Bitmine Increases Its ETH Staking to $1.37 Billion as Year Ends

Bitmine Immersion Technologies has expanded its Ethereum staking to $1.37 billion, with an additional $352 million worth of Ether staking on December 31. The move highlights the company’s ongoing commitment to Ethereum, even as the broader crypto market faces a slow period at the close of 2025. 

On-chain data tracked by OnChain Lens showed Bitmine staking 118,944 ETH, valued at around $352.16 million at the time. Following the transaction, the firm’s total staked Ether climbed to 461,504 ETH, worth roughly $1.37 billion at prevailing market prices.

The staking activity suggests Bitmine is positioning its holdings for a longer-term horizon rather than seeking short-term profits.

Onchain Labs also flagged a newly created wallet that received 32,938 ETH from trading firm FalconX. On-chain activity shows that the address is probably associated with Bitmine, which contributes to the fact that the company is still expanding its exposure instead of merely rearranging the current resources. 

Continued accumulation from Bitmine

This activity caps a busy month for Bitmine. Over the past week alone, Bitmine accumulated more than 44,000 ETH, while earlier in December it executed several large purchases, including a single-day buy of 67,886 ETH worth about $201 million on December 24.

Additional transactions of roughly $88 million and $97.6 million further expanded its treasury. According to data from Strategic ETH Reserve, Bitmine’s total Ether holdings now stand at around 4.07 million ETH, valued at approximately $12 billion. 

At the time of writing, Ethereum (ETH) was trading at $2,972.82, with a 24-hour trading volume of about $17.94 billion. Ethereum’s current market value is around $358.8 billion, according to CoinMarketCap data.

Strategic shift and market context

Bitmine Immersion Technologies Inc. (NYSE: BMNR), which is led by Fundstrat Co-Founder Tom Lee, has experienced significant strategic changes in 2025. The company was previously recognized as a prominent Bitcoin mining hardware provider, but has since re-oriented its business around massive asset holdings of digital assets, with Ethereum being the core of its treasury policy.

By current estimates from Strategic ETH Reserve data, Bitmine controls the largest known corporate ETH treasury and ranks second globally among crypto treasuries, behind only Strategy’s Bitcoin holdings.  The firm has stated an ambition to eventually own close to 5% of Ethereum’s circulating supply. 

With average ETH entry prices of about $3,960, Bitmine is believed to be carrying billions of dollars of unrealized losses in the present market decline. This notwithstanding, accumulation has proceeded during price weakness.

Lee has also explained the recent market weakness by the fact that year-end tax-loss sales in the US are at their highest point between December 26 and December 30, as well as reduced institutional participation during the Christmas period.

What comes next

Looking ahead, Bitmine intends to roll out its Made in America Validator Network (MAVAN) in the first quarter of 2026, which will run Ethereum validators based in the US, according to the official announcement on PR Newswire.

The company’s next shareholder meeting is scheduled for January 15, 2026, in Las Vegas, during which the management is likely to provide more information on its Ethereum treasury plan.

Since Ethereum has been trading below its previous highs, the activities of Bitmine demonstrate the opposite of a company strategy, consistent accumulation and staking in the face of market consolidation, and not a withdrawal in the case of uncertainty.
