BitMine nears 5% Ethereum threshold, yet stock valuation rules dictate its next move

On Sept. 28, Ethereum treasury firm BitMine Immersion Technologies announced it held 6,001,302 ETH. This leaves the organization just 103,698 tokens shy of its objective to control 5% of the total Ethereum supply, calculated using the firm’s most recent supply projections.

Acquiring this remaining balance at BitMine’s Sept. 27 reference price equates to an expenditure of approximately $279.8 million. As of that same date, the organization disclosed holding $672 million in cash alongside marketable securities.

This projected acquisition cost represents about 42% of that available pool. While reaching the milestone appears manageable on paper, the price and supply of ETH fluctuate dynamically, and BitMine has not formally designated these funds exclusively for this goal.

As the enterprise nears its benchmark, its upcoming decisions carry heavier weight: whether to continue accumulating ETH, maintain cash reserves, execute share buybacks, or generate revenue from the tokens already in its possession.

BitMine revealed it added 17,362 ETH over the most recent week, marking roughly a 37% decrease compared to the 27,562 ETH acquired during the preceding week. The company notes it has maintained weekly ETH purchases since kicking off this strategy in June 2025.

Back in July, the firm bought back approximately 5.5 million BMNR shares at a mean price of $15.6156—totaling roughly $85.9 million—while simultaneously purchasing 7,430 ETH that week. Chairman Tom Lee explained that the slower pace of ETH accumulation was a direct result of the share repurchase program.

This previous action demonstrates that leadership has weighed equity value against further ETH accumulation, though that July choice does not dictate future maneuvers.

According to a Sept. 24 study published by DWF Labs, only four out of the 20 largest digital asset treasury companies (evaluated by assets under management within their sample) traded at a valuation exceeding their actual crypto holdings, a metric referred to as mNAV.

Issuing stock at a premium allows companies to fund token purchases without triggering severe dilution concerns. DWF anticipates that management execution and capital allocation structures will grow increasingly critical as these stock premiums diminish.

This insight underscores why a treasury company’s market valuation serves as a foundational element for any strategy to keep gathering crypto once a stated target is met.

Although BitMine does not face an immediate cash crunch based on its stated reference price, the core question is whether its subsequent deployment of capital delivers greater value to shareholders than simply buying more ETH.

What the existing Ethereum position can earn

BitMine reported having 5,067,309 ETH staked as of Sept. 27, which accounts for roughly 84% of its entire stockpile. Based on a seven-day measured yield of 2.62%, the enterprise estimates $358 million in annualized staking income at its current staked volume, and up to $424 million in annualized rewards if 100% of its ETH reserves are staked.

Furthermore, BitMine stated that its MAVAN staking platform has scaled to accommodate institutional clients, custodians, and partners. At present, the primary quantified alternative to simply stacking more tokens is the projected yield generated by its existing reserves.

In July, Lee hinted at a deliberate, gradual approach toward the 5% threshold, alongside increased spending directed at staking infrastructure and Ethereum-focused investments. Surpassing the 5% mark will inevitably draw sharper scrutiny regarding whether metrics like ETH per share, staking yields, preserved cash, or BMNR buybacks will best justify the value of the next capital allocation.

Lee is slated to deliver a keynote address titled “Ethereum’s Wall Street Moment” at Korea Blockchain Week on Sept. 30.

That event may provide investors with clearer visibility into the firm’s strategy. For now, BitMine has proven it possesses the financial capacity to hit its 5% target under current pricing assumptions, while its roadmap for subsequent capital deployment remains open-ended.
