BMNR ETH Hits 5.79M, mNAV at 0.86x | Week of Jul 27
BitMine reported another week of ETH accumulation, adding 9,946 ETH to bring holdings to 5.79 million tokens, roughly 4.8% of all ETH in existence, with total crypto and cash of $11.8 billion (Source). Tom Lee also announced 6.1 million shares repurchased this week, up from 5.5 million the prior week, bringing the buyback total to 11.6 million shares since July 1. He framed the accelerated buyback as a response to the ETH/BTC ratio hitting a three-month high of 0.3000, and pointed to $2,000 and $2,500 as the next technical levels for ETH.
That's the press release. Here's what our data shows underneath it.
The buyback headline and the dilution reality
BitMine repurchased 6.1 million shares this week. Shares outstanding still rose by 8.09 million, from 631.6 million to 639.7 million. Do the math and gross issuance was roughly 14.2 million shares, more than double what the buyback retired.
This matters because it changes what the buyback actually accomplishes. Repurchasing stock at 0.855x NAV is genuinely accretive: you're retiring shares for less than the assets behind them are worth. But issuing shares at that same discount does the opposite, and BitMine issued more than it retired. The net effect shows up in ETH concentration. Last week each 1,000 shares represented 9.15 ETH. This week it's 9.05. ETH per share fell about 1.1% in a week where the company bought ETH every single day of coverage and ran its largest buyback yet.
NAV per share still rose 0.90% to $18.46, but that was ETH's price doing the work, not capital allocation. Strip out the market move and shareholders own a slightly smaller slice of the treasury than they did seven days ago. You can stress-test how issuance and buybacks interact at different mNAV levels in our NAV Analysis tool.
The discount got worse, not better
The stock closed the week at $15.79 against $18.46 of NAV per share, an mNAV of 0.855x, down from 0.909x last week. So the discount widened by more than five points during the largest common stock buyback any digital asset treasury has ever executed. The stock fell about 5% while NAV per share rose. If you're new to why that multiple matters, What mNAV Means covers it.
The uncomfortable read: the market is either skeptical of the net dilution, pricing in the falling odds of the Clarity Act passing in 2026, or simply not paying up for ETH exposure with the token at $1,955 against BitMine's average buy price of $3,096.66. The treasury is underwater roughly 37% on its cost basis. Buybacks narrow discounts when they shrink the share count. This one didn't.

The 6M goal and everything else
Progress toward the 6 million ETH target sits at 96.46%, with about 212,600 ETH to go. Our model estimates 44 days remaining, which assumes the pace picks up meaningfully from this week's 9,946 ETH. At the current weekly rate it would take closer to five months, so watch whether accumulation accelerates or the timeline slips. Live progress is on the Treasury Dashboard.
Staking was flat at 4.92 million ETH, about 85% of the position. Cash holds at $268 million. Nothing notable there, and that's fine; the yield keeps compounding regardless.
What it means for investors
The bull case this week is real: ETH/BTC at a three-month high, ETH at a ten-week high, an accretive buyback running below NAV, and management that has bought ETH every week for over a year. If Lee and DeMark are right about $2,000 and $2,500, NAV per share moves fast, and a 0.855x entry looks cheap in hindsight.
But the number to watch isn't the buyback total. It's ETH per share, and it went down. A treasury company's entire pitch is growing crypto exposure per share faster than you could by holding the token yourself. This week it did the opposite while advertising a record buyback. One week isn't a trend. Two or three would be. If gross issuance keeps outrunning repurchases at a discount to NAV, the widening mNAV gap is the market telling you it noticed.
