BitMine Resumes Buybacks as ETH Treasury Nears 5% of Supply

| cryptopotato.com
BitMine Immersion Technologies has resumed share buybacks while expanding its Ethereum treasury and staking activity. The company repurchased 2.04 million shares last week at an average price of $22.48, its first reported buyback since mid-August. This brings its 2026 total to 22.9 million shares, costing $399.6 million at an average of $17.48. Earlier, BitMine said it had spent $350 million to buy back and retire 21 million shares between mid-July and August 17, under an authorization expanded to $4 billion. Chairman Tom Lee said the shares were undervalued relative to the company’s digital-asset holdings. He also noted that BMNR fell about 3% over a comparison period when ETH declined roughly 10%, attributing some of the stock’s relative resilience to the buybacks. BitMine added 10,452 ETH during the latest reported week, bringing its treasury to 6,051,933 ETH, or about 4.95% of total supply and close to its 5% target. As of October 25, it had 5,227,037 ETH staked, up from 5,067,309 after a pause of nearly three months. Lee estimated annualized staking revenue at $318 million at the current staking level, or $368 million if the full treasury were staked. The company previously said about 87% of its ETH was staked through MAVAN and estimated annualized staking revenue of $250 million to $363 million, depending on yields. BitMine valued ETH at $2,356 and put its crypto, cash and equity holdings at $15 billion; cash and marketable securities stood at $514 million. Lee attributed ETH’s 13% fall from its recent peak to broader risk-off conditions, noting that US semiconductor stocks had fallen 20%. The buybacks reduce the share count and increase remaining shareholders’ proportional exposure to BitMine’s assets and staking income, but also use funds that could otherwise support further ETH purchases. These are company-specific developments, not evidence of a broader crypto-market trend; traders will be watching ETH prices, staking yields and the pace of future buybacks and accumulation.
Neutral
The news is primarily about BitMine’s corporate treasury and stock-buyback strategy, rather than a change in Ethereum’s network fundamentals or market-wide demand. Its continued ETH accumulation and higher staking balance may signal confidence and provide a modest supportive narrative for ETH. However, the purchases are small relative to the overall market, and the company’s buybacks do not directly create sustained buying pressure for ETH. In the short term, ETH is more likely to respond to broader risk appetite, price momentum and liquidity conditions; Lee’s account of a 13% retreat from the recent peak highlights that exposure. Over the longer term, BitMine’s stated goal of holding close to 5% of ETH supply and earning staking revenue could draw attention to institutional treasury demand, but that effect depends on continued accumulation and staking yields. Buybacks also consume cash that might otherwise fund ETH purchases, while the company’s cash and marketable securities have declined. As a result, the developments are not a clear directional catalyst for ETH, supporting a neutral assessment.
