BitMine Now Holds $15.7 Billion in Various Assets as Massive ETH Buying Spree Continues

BitMine Immersion Technologies (BMNR) reported an Ethereum (ETH) treasury of 5,929,198 tokens and combined crypto, cash, and moonshot holdings of $15.7 billion as of September 7, in an 8-K filed September 8 that also disclosed the end of the outside agreement running its staking operations.

BitMine marked its ETH at $2,495 per token, per Coinbase, leaving the total little changed from the $15.6 billion it reported a week earlier, when the stash crossed 5.9 million tokens on a 53,501 ETH purchase. The company added 28,086 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, which BitMine puts at 97% of the way to its goal of owning 5% of all ETH, a target it calls the Alchemy of 5%.

Staking Fee Switches to Flat Rate

BMNR Subsidiary One and Ethereum Tower LLC signed a mutual termination agreement on September 4, ending a management services agreement from March 24 under which Ethereum Tower collected a revenue participation fee, a share of net staking revenue on company-owned ETH.

The original contract carried an initial ten-year term and let BitMine exit for convenience on 180 days’ notice, a period both sides waived. BitMine said it paid no material early termination penalties and that amounts accrued through September 3 remain payable.

A BitMine subsidiary then signed a new advisory agreement with American Validator LLC, an affiliate of Ethereum Tower, effective September 4, for a flat fee of 1.50% of staking rewards on staked ether.

BitMine stakes 5,067,309 ETH, worth $12.6 billion at its mark and about 85% of the treasury, through MAVAN, the in-house Made in America Validator Network it built this year. Chairman Tom Lee put projected annualized staking revenue at $330 million, rising to $386 million once the ether is fully staked, at a 2.61% seven-day yield.

Cash Rebuilds to $593 Million

Total cash and marketable securities reached $593 million on September 7, up from $541 million a week earlier and $78 million on August 16. Alongside the ether, BitMine held 211 Bitcoin (BTC), a $180 million stake in Beast Industries and a $91 million stake in Eightco Holdings (ORBS), which the release described as one of the only listed equities offering indirect exposure to OpenAI.

BitMine is among the most heavily traded US stocks, at $1.10 billion in average daily dollar volume in the five days to September 4, 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 840,447 Bitcoin worth about $66 billion
