Bitmine Immersion Technologies (BMNR): Valuation Check After Massive Ethereum Accumulation

December 9, 2025

Bitmine Immersion Technologies (BMNR) just stepped on the gas again, lifting its Ethereum stash to more than 3.86 million ETH, or over 3% of the network, right after the Fusaka upgrade and improving macro signals.

See our latest analysis for Bitmine Immersion Technologies.

That aggressive ETH buying spree comes after a bruising few months, with a 90 day share price return of minus 19.6% and a 30 day share price return of minus 10.9%, even though the year to date share price return is a huge 412% and the 1 year total shareholder return sits at 353.8%. This suggests long term momentum is still very much intact despite recent volatility.

If Bitmine’s swingy chart has you rethinking concentration risk, this could be a useful moment to explore fast growing stocks with high insider ownership as potential complementary ideas.

With BMNR now trading nearly 50% below consensus target despite a huge run, investors face a key question: does this represent a rare mispriced levered bet on Ethereum, or has the market already baked in Bitmine’s next leg of growth?

Price-to-Earnings of 41.9x: Is it justified?

Bitmine Immersion Technologies trades at a steep 41.9x price to earnings multiple at the last close of $35.84, signaling a rich valuation versus peers.

The price to earnings ratio compares the company’s share price with its earnings per share, a common way to judge how much investors pay for current profitability in software and crypto exposed names. For BMNR, a higher multiple suggests the market is factoring in robust future earnings growth or sustained Ethereum linked profitability following its recent move into solid profitability.

However, BMNR’s 41.9x price to earnings stands well above both the US Software industry average of 32x and the closer peer average of 28.7x. This indicates investors are paying a significant premium for its earnings stream compared to alternatives in the same space. Unless future earnings growth outpaces the broader software group by a wide margin, this premium could be seen as overpayment rather than a modest upgrade.

Result: Price-to-Earnings of 41.9x (OVERVALUED)

However, there are real risks, including an Ethereum price reversal or regulatory pressure on digital asset treasuries, that could rapidly deflate Bitmine’s premium.
