Bitmine Immersion Technologies now holds 6,016,414 ETH after buying another 15,112 tokens last week, a position of roughly $16.4 billion that equals 4.9 percent of ethereum’s 122.1 million token supply. The October 5 holdings update also showed 5,067,309 ETH staked, worth $13.8 billion at a reference price of $2,726, which is 84 percent of the company’s stack and the largest staked ethereum balance held by any single entity.
The company has bought ETH every week since launching its treasury strategy on June 30, 2025, chairman Tom Lee said. The latest purchase followed a 17,362 ETH buy in late September that first pushed the treasury past the 6 million mark. Bitmine’s total crypto, cash and marketable securities position now stands at $17.4 billion, including 214 BTC, a $180 million stake in Beast Industries, a $117 million stake in Eightco Holdings and $643 million in cash and securities.
The staking math
Bitmine’s own staking operations produced a seven-day annualized yield of 2.63 percent. Under current assumptions that puts projected annualized staking revenue at $363 million, with ETH rewards at scale projected near $431 million a year. The stack sits on MAVAN, the Made in America Validator Network the company built, which has opened to institutional investors, custodians and ecosystem partners rather than serving only Bitmine’s own balance sheet.
Staking 84 percent of a treasury this size locks the position to the network’s exit mechanics. Ethereum’s validator exit queue drew attention this month when MetaMask pulled about $1.4 billion in ETH from staking after block rewards were diverted to a Tornado Cash-funded wallet, and the exit queue reached 773,000 ETH around that episode. For Bitmine the queue matters in the other direction: exiting 5 million ETH would take far longer than any portfolio decision cycle, a structural commitment the 2.63 percent yield is compensation for holding.
Approaching the 5 percent target
The company has a stated target of owning 5 percent of ETH supply. At 4.9 percent it is about 122,000 tokens short. Weekly buys of the last two weeks averaged roughly 16,000 ETH, so the remaining gap is a matter of weeks at the current pace, not months. Crossing 5 percent matters beyond symbolism: it would put Bitmine’s reported holdings among the largest single concentration percentages in ether’s history, and it invites the governance scrutiny that comes with it.
Liquidity is the constraint that grows with the position. Daily spot volume for ETH runs in the low tens of billions of dollars across venues, so a treasury of this size cannot turn into an active seller without moving against itself. The staked majority makes that a feature rather than a bug for the holding thesis, and MAVAN’s institutional staking business would suffer directly if the anchor tenant started unwinding.
How the market priced it
ETH at $2,726 under the company’s reference price has been choppy through September and early October. Derivatives positioning is bitcoin-dominated for now, so ether’s structural story is running through treasuries and staking rather than leverage. Bitmine’s update lands the same week as its own rising benchmarks: the September 28 disclosure put total holdings at $17.2 billion, and the October 4 figure rose to $17.4 billion on the weekly buy and reference-price drift.
The distinction between the two headline numbers readers see, $16.4 billion of ETH and $17.4 billion of total assets, is the non-ETH sleeve: cash, the two equity stakes, and the small bitcoin position. At this scale the coin position is 94 percent of the story, and the weekly cadence of the buys is the only discretionary signal the company sends. That cadence has not broken once in 15 months.
Why the concentrating trend keeps running
Ethereum now has entrenching holders tracking each other in public: Bitmine at 4.9 percent of supply, competing treasury companies accumulating against the same float math, and stETH-plus-custodial balances concentrated through Lido and exchanges. Treasury companies buying and staking take tokens off liquid float, which lowers float velocity and makes the staking yield itself part of the pitch. Bitmine’s own filings lean on that: projected staking revenue of $363 million is pitched to shareholders alongside the 4.9 percent ownership, the two claims reinforcing each other.
The company’s October message to shareholders goes further, with the title “Crypto bull underway, this cycle likely the largest.” That wording is a positioning statement, not a filing, and it is worth reading as sales language for a stock whose equity value is now overwhelmingly a leveraged expression of one token’s direction. BMNR shareholders do not get a claim on ETH itself, only on the company that holds it, so financing costs and share count matter as much as the coin.
The counterweight is exit risk in a drawdown. A treasury that owns both equity calls on ETH exposure and the validator economics of the network becomes a forced hold, whether or not the price path cooperates. Bitmine’s buy streak through 2025 and 2026 has spanned both rising and falling token regimes, so the firm has not yet been tested by a genuine treasury-level exit decision. The staked 84 percent makes that test harder the longer it stays staked.
This week’s update keeps the streak alive and moves the company within weeks of its stated ownership target at the current pace. The next filing is the one to watch: it should show whether the 5 percent line gets crossed, and whether the staking balance grows in step with the buys as a matter of policy.
