BitMine affirmed that it had bought 40,302 ETH in the last one week, which was its biggest Ethereum purchase ever of 2026. This makes the total amount of ETH holdings 4,243,338 tokens which rank the company among the world leaders in Ethereum treasuries.

At present circulating supply rates, BitMine has taken over 3.52% of the total ETH, making it a step towards its long-term goal of controlling 5% of the network supply. The fact that it has attained close to 70% of that target within six months is indicative of the speed and frequency of its amassing policy.

The company maintains 193 BTC along with Ethereum, however, ETH obviously takes the center-stage of its balance sheet and long-term thesis.

BitMine reported $12.8 billion in combined crypto assets, cash, and strategic investments. Ethereum accounts for the bulk of this value, supported by $682 million in cash that gives the firm flexibility to continue buying during market volatility.

The balance sheet also includes a recently closed $200 million investment in Beast Industries, which BitMine categorizes as a high-upside strategic holding. Additional smaller positions, such as its stake in Eightco Holdings, round out the portfolio.

Beyond asset size, BitMine has also emerged as one of the most liquid crypto-linked stocks in the U.S. BMNR now averages $1.2 billion in daily trading volume, ranking it among the top 100 most traded U.S. equities.

More than 2,009,267 ETH are already staked, representing nearly half of BitMine’s Ethereum treasury. This figure increased by over 170,000 ETH in a single week, reflecting how quickly the company is deploying assets into yield-generating infrastructure.

With the current Composite Ethereum Staking Rate of 2.8%, BitMine estimates that its annual staking revenue is about $374 million when the whole ETH will be under staking. This number is equivalent to more than $1 million per day from the protocol’s native reward. 

To support this scale, BitMine is developing MAVAN (Made in America Validator Network), a commercial staking platform launched in the first quarter of 2026. According to the company, MAVAN will provide safe validator infrastructure, located in the U.S., while handling a significant share of its own ETH stake.
