BMNR Hits 5.82M ETH at 0.956x mNAV | Week of Aug 17

BitMine reported 5.82 million ETH this week, now 4.8% of the entire circulating supply, alongside $11.4 billion in total crypto and cash holdings (Source). Tom Lee pointed to the ETH/BTC ratio at 0.02994 and rising, framed easing financial conditions as a tailwind, and confirmed the company has now bought ETH every single week since the treasury strategy launched on June 30, 2025. Fourteen months without a miss. The company also reiterated that its buyback, 20.8 million shares repurchased since July 1 under the $4 billion authorization, remains the largest ever executed by any crypto DAT.

That's the press release. Here's what our data actually shows.

The buy was small, and the discount is the story

This week's purchase was 9,926 ETH, a +0.17% increase in holdings. That's a maintenance buy, not an accumulation push. The streak stays alive, but the pace matters, and I'll come back to why.

The number worth staring at is the mNAV: 0.956x. BMNR closed the week at $18.08 against a NAV per share of $18.90, meaning you can buy the company's ETH through the stock at roughly a 4.4% discount to what the treasury is worth. NAV per share actually rose 0.70% this week (+$0.13) and the discount widened anyway, with mNAV slipping another 0.008x. The market added value to the treasury and subtracted value from the multiple in the same week.

There's a wrinkle in the buyback narrative too. Management touts 20.8 million shares repurchased since July, yet shares outstanding rose 2,470,847 this week (+0.41%). Net issuance is outrunning net retirement right now. That's not automatically bad, since NAV per share still grew, so whatever was issued was more than covered by treasury gains. But if you're holding BMNR partly for the buyback story, watch the net share count on our Treasury Dashboard, not the gross repurchase headline.

The 6M goal is close, but the math is tightening

Progress toward 6 million ETH sits at 96.92%, which leaves 184,836 tokens to go with an estimated 92 days remaining. At this week's pace of 9,926 ETH, that gap takes about 18.6 weeks to close. The clock allows roughly 13. So either purchase velocity picks up meaningfully in the back half, or the timeline slips. Given the discount to NAV, aggressive equity issuance to fund buys would be value-destructive per share, which is probably why this week's buy was modest. Run the scenarios yourself in our NAV Analysis tool; the tradeoff between hitting the target and protecting NAV per share is the whole game from here.

Staking stayed flat at 5,067,309 ETH, worth about $9.6 billion at current prices. That's 87.1% of the entire position generating yield on MAVAN, and the un-staked remainder plus $78 million in cash is the dry powder. Also worth remembering: the average buy price across the whole treasury is $3,081.89 against ETH at $1,897.31. The position is roughly 38% underwater on cost basis. The thesis here has never been about the entry price, but anyone modeling BMNR should carry that number.

What this means for investors

A sub-1.0 mNAV inverts the usual DAT playbook. When these vehicles trade at a premium, issuing shares to buy ETH is accretive and the flywheel spins. At 0.956x, every share issued to buy ETH destroys a little NAV per share, while every share bought back below NAV creates it. The rational move at these levels is buybacks over accumulation, and the small 9,926 ETH purchase suggests management sees it the same way. The tension is the 6M goal, which pulls in the opposite direction.

For a buyer today, the setup is straightforward: you get $18.90 of treasury per share for $18.08, a 14-month unbroken accumulation record, 87% of the stack earning staking yield, and Lee's macro case (Wall Street tokenization, agentic AI on-chain, a rising ETH/BTC ratio) as the upside kicker. The risks are equally clear. ETH sits well below the treasury's cost basis, dilution is currently outpacing the buyback, and the goal timeline is getting tight. The discount is your margin of safety. Whether it's enough depends on your ETH view, not your BMNR view.

Frequently Asked Questions

What does an mNAV of 0.956x actually mean? mNAV is the stock's market cap divided by the value of its treasury (net asset value). At 0.956x, BMNR trades below the value of the ETH and cash it holds, so each dollar of stock buys about $1.05 of treasury assets. Above 1.0x is a premium; below is a discount. See What mNAV Means for the full breakdown.

Why did shares outstanding rise if BitMine is running a record buyback? Buybacks and issuance happen simultaneously. The company has repurchased 20.8 million shares since July 1, but new issuance (ATM sales, compensation, or other programs) added more than the buyback retired this week, for a net gain of 2.47 million shares. NAV per share still rose, so the issuance wasn't dilutive to treasury value this week, but the net count is the number to track.

Is the 6 million ETH goal still achievable? Mathematically yes, but not at the current pace. Closing the remaining 184,836 ETH gap in 92 days requires roughly 14,000 ETH per week, about 40% above this week's purchase. With the stock below NAV, funding faster buys through share issuance would hurt per-share value, so watch whether staking yield and cash carry the load instead.
