BitMine Immersion Technologies has driven a notable Ethereum treasury expansion by buying more ETH this year. The company, BMNR, now holds about 2,069,443 ETH, roughly $9 billion as of September 2025. Chairman Tom Lee and management say the move supports a digital asset treasury strategy. This expansion ties into investments such as a $20 million stake in Eightco Holdings and a focus on Worldcoin-linked projects. The how was steady accumulation plus targeted strategic bets. The why centers on a perceived blockchain AI supercycle and long-term value capture.
BitMine’s latest move
BitMine’s purchases grew its ETH position faster than many public peers. BMNR paired new ETH buys with cash and Bitcoin holdings to balance risk. The Ethereum treasury expansion at BitMine follows an intentional buy-and-hold plan. The firm also invested in Eightco Holdings to back ecosystem projects. The stock jump after the Eightco news showed investor appetite for a digital asset treasury approach.
Why ETH matters
Ethereum remains the core engine behind smart contracts and many DeFi flows. The ETH thesis feeds BMNR’s Ethereum treasury expansion narrative. Management argues Ethereum benefits most from scaling, staking, and tokenized AI use-cases. A larger ETH stash positions BMNR to profit if network value rises with broader adoption. That aligns with the blockchain AI supercycle thesis.
Strategic Eightco bet
BMNR’s $20 million investment into Eightco Holdings links its treasury to new user-layer projects. Eightco’s Worldcoin-related roadmap is one example of where BMNR seeks value. The move is part of a diversified digital asset treasury policy, not a pure play on price. It aims to seed ecosystem growth that boosts long-term treasury returns.
Public crypto treasury ranking
With Bitcoin, cash and ETH combined, BMNR ranks among the largest public crypto treasuries. The Ethereum treasury expansion is now a headline for investors watching public treasuries. The size and mix give BMNR both exposure and flexibility in volatile markets. Public treasury strategies can move markets through signalling and accumulation.
Tom Lee’s playbook
Chairman Tom Lee frames the expansion as a long-term strategic position. The approach resembles corporate “other bets” that back emerging tech. BMNR’s playbook blends ETH accumulation, selective equity stakes, and cash reserves. Investors should watch execution and regulation as the strategy unfolds through September 2025.
