Bitmine Immersion Technologies (BMNR) shares declined approximately 7.7% in New York trading on Friday, intensifying scrutiny on one of the largest public Ethereum treasury strategies as the digital asset stumbled. The stock was last seen at $20.30, while ether traded near $2,221, down 3.4% on the day.
Ethereum Exposure Drives Stock Performance
The selloff highlights a key shift in Bitmine's investment narrative. Unlike traditional crypto mining firms, Bitmine's valuation increasingly hinges on the market's perception of its substantial Ethereum holdings rather than mining operations. A dip in ether prices transforms the stock into a leveraged bet on ETH's direction, rather than a pure mining play.
In a May 11 regulatory filing, Bitmine disclosed it held 5.2068 million ETH as of May 10, valued at approximately $2,366 per token, representing 4.31% of the total ETH supply. The company also owns 201 bitcoin, $775 million in cash, and stakes worth $200 million in Beast Industries and $88 million in Eightco Holdings. Executive Chairman Tom Lee indicated the firm plans to slow its weekly ETH purchases, noting that the previous pace of over 100,000 ETH per week would have pushed the treasury to 5% of supply by mid-July, well ahead of the late 2026 target.
Staking Revenue and Market Dynamics
Bitmine's staking operations, which involve locking tokens with blockchain validators in exchange for rewards, remain a secondary revenue stream. The company said its staking strategy depends on market conditions, returns, custody costs, and capital availability. Prediction market participants on Polymarket currently assign a 24% probability to Bitmine selling ETH in 2026, suggesting uncertainty about the long-term commitment to the strategy.
Peer Bit Digital, a publicly traded firm with both Ethereum and AI infrastructure exposure, reported late Thursday that first-quarter revenue fell 13.6% quarter-over-quarter to $27.9 million. The company held approximately 155,444 ETH as of March 31, while ETH staking revenue dropped 29.4% to $2.3 million. Although Bit Digital's ETH holdings are far smaller than Bitmine's, the competitive landscape for investor dollars remains intense, with both firms touting treasury strength, staking returns, and Ethereum's potential integration into mainstream finance and AI settlement systems.
Broader Portfolio and Risks
Bitmine also holds stakes in Eightco, which pegged its portfolio at around $340 million as of May 12. That includes indirect exposure to OpenAI, equity in Beast Industries, over 11,000 ETH, Worldcoin tokens, and $129 million in cash. Bitmine is listed among Eightco's institutional supporters, adding layers of complexity to its asset base.
The risks are clear. Bitmine's stock is tied to a volatile token, uncertain regulatory environment, and continued access to capital markets. In its offering documents, the company flagged that a sharp decline in ETH or bitcoin, problems at digital-asset platforms, or regulatory changes could severely impact common shares.
Market Outlook
Tom Lee has stated that ETH closing above $2,100 for the month would signal a shift in the crypto cycle. On Friday, ether managed to close just above that level. For Bitmine holders, the critical question is whether slowing ETH purchases will be sufficient to support the stock if ether remains near $2,200 rather than advancing.
