Tom Lee’s BitMine Adds Another $117 Million In Ether To Corporate Treasury In Largest ETH Purchase Of 2026 ⋆ ZyCrypto

Tom Lee-helmed BitMine Immersion Technologies has expanded its position as the world’s biggest Ethereum treasury firm, signaling continued confidence in Ethereum despite current market weakness.

BitMine added over 40,000 ETH worth an estimated $117 million last week as part of its long-term bid to accumulate 5% of the asset’s total supply.

Biggest Purchase Yet In 2026

BitMine disclosed on Monday that it had purchased 40,302 ETH over the past week, at a total cost of around $117.1 million.

The latest acquisition extends its Ethereum treasury to more than 4.24 million ETH tokens, around $12.2 billion worth, making it the largest Ethereum treasury and second-largest crypto treasury overall behind Michael Saylor Strategy’s Bitcoin stash (valued at around $62.5 billion). 

The NYSE American–listed company now holds around 3.52% of the entire Ethereum circulating supply. BitMine’s strategic goal is to amass 5% of the total ETH supply, currently equivalent to approximately 6.04 million ETH.

The latest increase is BitMine’s largest Ethereum buy so far in 2026, measured both by the amount of ETH and the U.S. dollar value at the time of the acquisition.

As of January 25, 2026, BitMine’s crypto and cash holdings now total $12.8 billion, including 193 BTC ($17 million), a $19 million stake in WLD treasury firm Eightco, $682 million in cash, and a $200 million stake in Beast Industries, the venture founded by YouTube star Jimmy Donaldson, better known as MrBeast.

BitMine’s total staked Ethereum stands at over 2 million — almost half its total holdings — turning a huge portion of its treasury into a yield-generating asset.  In other words, the company effectively locks its ETH tokens to help secure the proof-of-stake Ethereum network and earns protocol-issued staking rewards for doing so. 

“BitMine has staked more ETH than other entities in the world,” Chairman Tom Lee noted on Monday. “At scale (when BitMine’s ETH is fully staked by MAVAN and its staking partners), the ETH staking fee is $374 million annually (using 2.81% CESR), or greater than $1 million per day.”

Meanwhile, ETH is up 1.3% over the last 24 hours and trading at $2,927.88 — over 40.7% below its August all-time high of $4,946, according to CoinGecko.
