BitMine Immersion Technologies (BMNR) reported an Ethereum (ETH) treasury of 5,956,378 tokens and combined crypto, cash, and moonshot holdings of $15.8 billion as of September 13, in a press release and 8-K filed September 14.

BitMine marked its ether at $2,513 per token, up from the prior week’s $2,495 mark, per Coinbase, lifting the total to $15.7 billion from the $15.7 billion it reported a week earlier, when its stash reached 5.93 million tokens, and it switched staking to a flat 1.50% validator fee.

Staked Total Holds at 85%

The company added 27,180 ETH over the past week and has bought ether every week since the strategy began on June 30, 2025.

Those holdings equal 4.9% of the 122.0 million ETH in supply, unchanged from a week earlier, under a plan BitMine calls the Alchemy of 5%, its [target of owning 5% of all ether]. The company puts the treasury 98% of the way to that mark, 15 months into the strategy.

BitMine stakes 5,067,309 ETH, worth $12.7 billion at its mark and about 85% of the treasury, through MAVAN, the in-house Made in America Validator Network it built this year. That staked total has held unchanged across the last three weekly updates even as the token count rose.

Chairman Thomas “Tom” Lee put projected annualized staking revenue at $334 million, up from $330 million a week earlier, rising to $392 million once the ether is fully staked, at a 2.62% seven-day yield.

Lee said Ether was the best-performing macro asset in the third quarter, outperforming the S&P 500 by 5,866 basis points through September 11, with Ether, Solana, and Bitcoin the top three assets since June 30. He added that the ETH-to-BTC price ratio had reached its highest level since January 30.

Cash Falls to $549 Million

Total cash and marketable securities stood at $549 million on September 13, down from $593 million a week earlier. The release gave no reason for the drawdown. Alongside the ether, BitMine held 212 Bitcoin (BTC), a $180 million stake in Beast Industries and a $98 million stake in Eightco Holdings (ORBS), up from $91 million the previous week, which the company called one of the only listed equities offering investors indirect exposure to OpenAI.

BitMine ranked among the most heavily traded US stocks, at $924 million in average daily dollar volume over the four days to September 11, 98th of 5,704 listed names, according to Fundstrat. Its holdings rank first among corporate ether treasuries and second among all crypto treasuries, behind Strategy (MSTR), which the release said owns 845,080 Bitcoin worth about $71 billion.
