Bitmine Immersion Technologies said it purchased 71,524 Ether over the past week, increasing its total holdings to about 4.875 million ETH.
The company said that position represents roughly 4.04% of the total Ether supply, based on about 120.7 million tokens outstanding, and that it remains on a path to acquire up to 5% of global supply. Bitmine’s balance sheet also includes 198 Bitcoin and approximately $719 million in cash.
Bitmine called the latest buy its fastest weekly Ether accumulation since December 2025. CoinGecko data show Bitmine is the largest public Ethereum treasury by a wide margin: SharpLink holds about 868,699 ETH and The Ether Machine about 496,712 ETH.
Over the past 30 days Bitmine was one of the few public Ethereum treasuries to increase holdings. Exodus Movement was the only other company in the dataset to add, buying 17 ETH to bring its total to 1,857 ETH.
Chairman Tom Lee said Ether has outperformed traditional assets in recent weeks, citing demand tied to tokenization activity on Wall Street and growing use of public blockchains by AI systems. According to CoinGecko, Ether is up about 7% over the past month, narrowing its year-to-date decline to roughly 25%.
A sizable portion of Bitmine’s Ether is staked through its in-house MAVAN platform: about 3.33 million ETH are currently staked, with projected annual rewards of roughly $310 million based on recent yields.
The announcement follows Bitmine’s April 9 debut on the New York Stock Exchange after uplisting from NYSE American, a move that typically signals stricter listing standards and broader institutional access.

Strategy now holds 780,897 BTC, purchased for a total of $59.02 billion, with just over 19,000 BTC remaining to reach 800,000.
