BMNR Crosses 6M ETH | Week of October 5, 2026

BitMine announced this week that its ETH holdings have reached 6.02 million tokens, with total crypto, cash, and marketable securities of $17.4 billion. The company bought 15,112 ETH over the past week, extending a streak of buying every single week since the treasury strategy launched on June 30, 2025. Chairman Tom Lee highlighted that BMNR outperformed ETH by 731bp over the first nine months of 2026 and pointed to 21 million shares repurchased this year as the largest crypto treasury buyback on record. BitMine now holds 4.9% of all ETH in existence, with 5,067,309 ETH staked on the MAVAN platform. Source

The headline is the milestone. Our Treasury Dashboard shows the 6 million ETH goal officially cleared at 100.27%. That target has anchored this entire accumulation campaign, and it's done. The question now is what BitMine does with a balance sheet this size when the obvious finish line is behind it.

The week underneath the milestone

Here's what the press release doesn't emphasize. ETH holdings grew 0.25% this week. Shares outstanding grew 0.43%. When your share count expands faster than your ETH stack, each share's claim on the treasury shrinks, full stop. And it happened while the stock traded below NAV, which makes equity issuance the most expensive possible way to fund purchases. Selling dollar bills for 93 cents to buy ETH is not a strategy anyone would write down on purpose.

That's the tension in Lee's framing this week. He's touting 21 million shares bought back in 2026, and the buyback is real at the annual scale. But this specific week, 2.6 million net new shares hit the count. Both things can be true. Readers should watch the weekly direction, not the annual talking point.

NAV per share still rose, up $0.14 to $28.13, which tells you ETH's price action did the heavy lifting rather than treasury management. Our NAV Analysis lets you decompose exactly how much of any week's NAV move comes from price versus accumulation versus dilution. This week, it was mostly price.

The discount deepened

MNAV fell from 0.959x to 0.934x, meaning the market now prices BMNR at a 6.6% discount to the liquid value of its holdings. If you're new to the multiple, What mNAV Means covers why treasury stocks swing between premium and discount. The short version: at 0.934x, every dollar of BitMine's ETH costs a buyer of the stock about 93 cents. Last week it was 96 cents. The discount is widening even as the company hits its signature goal, which suggests the market has already priced the milestone and is now asking the harder question about per-share value creation.

One more number worth sitting with. The average buy price across the treasury is $3,015.62 against a current ETH price of $2,710.67, so the aggregate position is roughly 10% underwater on cost. That's not a crisis for a staking operation generating yield on 84% of its stack (staking was flat this week at 5.07 million ETH, still the largest staked position of any entity). But it does mean the bull case rests on ETH recovering, not on the entry prices.

What this means for investors

The 6M goal is complete, the accumulation streak is intact, and the staking base is enormous. Those are the durable positives. The softer signals are a weekly purchase that was small by this company's standards, net dilution during a sub-NAV week, and a discount that widened by 2.5 points. With $643 million in cash and roughly 949,000 ETH sitting unstaked, BitMine has real optionality here: stake more, buy back stock at a discount, or keep accumulating. Buying back shares at 0.934x is mathematically the best ETH-per-share trade available to them right now. Whether management agrees is next week's story.

Frequently Asked Questions

What does an MNAV of 0.934x mean for BMNR shareholders? It means the stock trades at 93.4% of the per-share value of BitMine's ETH, cash, and securities. Buyers get exposure to the treasury at a 6.6% discount; existing holders see the market valuing the company below its liquid assets.

Why does share dilution matter if BitMine keeps buying ETH? Because investors own shares, not the treasury directly. If shares outstanding grow faster than ETH holdings (0.43% vs 0.25% this week), each share's slice of the ETH stack shrinks, even when the total pile grows.

Is the 6 million ETH goal actually complete? Yes. At 6,016,414 ETH, BitMine sits at 100.27% of the target, holding 4.9% of the total ETH supply. The company has not yet announced a new accumulation target.
