BitMine Immersion Technologies bought an additional 111,942 ETH over the past week.
CoinPost, a blockchain outlet, reported on May 27 that the purchase was worth 370 billion yen, or about 3.5 trillion won. BitMine's total ether holdings rose to 5,390,404.
The amount equals 4.47 percent of Ethereum's total supply of 120.7 million. The company said the total value of its holdings is about $11.5 billion if ETH is priced at $2,134. The weekly purchase is the largest since December 2025.
Tom Lee (톰 리), BitMine's board chairman, said he viewed the recent dip in ETH below $2,200 as a buying opportunity. "I saw the phase where Ethereum fell below $2,200 as an attractive buying opportunity," he said in explaining the additional purchases.
The company is expanding staking returns as well, rather than only holding ether. As of May 25, BitMine had 4,712,917 ETH staked. The company put the annualised yield at 2.75 percent as of May 7, and sees annual staking income reaching $276 million at full operation on that basis.
The operation is centred on the institutional staking infrastructure dubbed the Made in America Validator Network, or MAVAN. The platform was originally developed for BitMine's own Ethereum treasury operations, and it plans to broaden services to custodians and institutional investors. The company is already staking some ether on the platform.
BitMine's total holdings, including cryptocurrencies, cash and so-called "moonshot" assets, were tallied at $12.3 billion. The asset mix has ETH as the biggest portion and includes $444 million in cash, a $200 million investment in Beast Industries and a $95 million investment in Eightco Holdings.
The market views BitMine's expanded buying as a move that goes beyond a simple treasury strategy and also takes into account monetising the Ethereum network and expanding its institutional services business. In this 흐름, BitMine completed a transfer listing on April 9 from NYSE American to the NYSE main market, and it is keeping the same ticker symbol, BMNR.
Lee also set out the company's long-term goals. "Wall Street's asset tokenisation and agentic artificial intelligence (AI) are both acting as tailwinds for Ethereum," he said, referring to the achievability of a "5 percent alchemy" strategy aimed at securing 5 percent of Ethereum's supply within the year. BitMine's current holdings have risen to about 89 percent of that goal.
Key points to watch going forward include whether BitMine will keep buying to reach the 5 percent target and whether it can turn its ETH holding strategy into a business by expanding its in-house staking infrastructure to outside institutions. Ethereum price volatility, staking yields and the pace of institutional inflows are also expected to have an impact.
