Bitmine Immersion Technologies pulled off something rare in August: a 46.5% stock gain driven by a methodical pivot from Bitcoin mining infrastructure to becoming one of the largest public holders of Ethereum on the planet.
BMNR shares climbed from around $18 to above $26 over the course of the month, driven by a combination of aggressive ETH accumulation, a massive share buyback program, and staking revenues that are starting to look like a legitimate business model rather than a crypto side hustle.
The numbers behind the move
By early August, Bitmine’s total asset holdings exceeded $11 billion. By the end of the month, that figure had swelled to approximately $14.9 billion, a nearly 35% increase in a matter of weeks.
The centerpiece of that portfolio: roughly 5.8 million ETH as of early August, representing about 4.8% of Ethereum’s entire circulating supply. The company continued adding tens of thousands of ETH on a weekly basis throughout the month, pushing total holdings even higher.
About 87% of the company’s ETH holdings are actively staked, generating projected annualized revenues between $250 million and $330 million. On the capital return side, Bitmine has repurchased more than 19 million shares since July 1, 2026, as part of a $4 billion buyback program. Chairman Tom Lee framed the initiative as a response to the stock trading at a persistent discount to its net asset value.
From mining rigs to Ethereum vaults
Bitmine’s origin story is rooted in Bitcoin mining, specifically immersion cooling technology for mining hardware. The pivot to an Ethereum-centric treasury model represents one of the more dramatic corporate transformations in the digital asset space.
Bitmine isn’t the first public company to build a crypto treasury. MicroStrategy famously pioneered the Bitcoin treasury model years ago, accumulating tens of billions of dollars worth of BTC and inspiring a wave of imitators. But Bitmine’s Ethereum-first approach is a meaningful departure from that playbook, reflecting a bet that ETH’s staking yield and role in decentralized finance give it a different value proposition than Bitcoin’s “digital gold” narrative.
What the pivot signals for the broader market
The staking revenue angle is particularly notable. A projection of $250 million to $330 million in annualized revenue from staking alone gives traditional finance investors something they can model in a spreadsheet.
By repurchasing shares when the stock trades below net asset value, Bitmine is essentially telling the market: we think our ETH is worth more than you’re giving us credit for.
Weekly gains of up to 26% during August also suggest the stock is attracting momentum-driven traders alongside fundamental investors.
