BitMine’s Buyback Is Doing More Work Than Its ETH Buy This Week

MakeCryippreferred on

BitMine Immersion Technologies (NYSE: BMNR) added 9,946 ETH over the past week, the second smallest weekly purchase since it started the treasury program on June 30, 2025, smaller only than the 7,430 ETH it bought on July 20. This week’s update showed the stock moving on the buyback, not the coin count: BMNR was up double digits intraday Monday, trading in the $17.79 to $17.84 range.

The Math Behind the Pop

BitMine now holds 5,787,414 ETH, valued at $1,948 per token as of July 26, alongside 208 BTC, a $180 million stake in Beast Industries, and a $61 million stake in Eightco Holdings, a combined crypto, cash, and moonshot total of $11.8 billion. The full breakdown is in the company’s 8-K filing with the SEC.

That ETH count barely moved week over week, up just 0.17%. The share count moved more. BitMine repurchased 6.1 million shares this week, up from 5.5 million the week before, bringing total repurchases since July 1 to 11.6 million shares under its $4 billion buyback authorization. The incentive here isn’t subtle: buying back stock while ETH holdings stay flat mechanically raises ETH per share without requiring new capital deployed into the token itself. That’s the lever BitMine pulled this week, not incremental accumulation.

Where the Capital Is Actually Coming From

Fund a buyback and a treasury program at the same time, and the cash side thins. BitMine’s cash and marketable securities fell from $385 million on July 19 to $268 million this week, a 30% drop in seven days. Set against the slowing ETH purchase pace, the sequence reads less like two independent programs and more like one cash pool being reallocated toward the buyback as the primary lever for near term share price support.

July’s Purchase Timeline

BitMine’s own weekly disclosures report totals of 42,197 ETH for the week ending July 6, 27,801 ETH for the week ending July 13, and 7,430 ETH for the week ending July 20. Separate reporting on individual on-chain purchases inside those weeks shows more activity than the weekly totals alone suggest:

• July 6: Bitmine purchased 42,197 ETH, increasing its total Ethereum treasury to 5.74 million ETH, in line with the company’s official weekly update.
• July 8: On-chain data indicated that Bitmine acquired an additional 40,000 ETH worth $71.6 million through FalconX and Kraken, based on transfers recorded on July 7.
• July 10: On-chain transfers suggested Bitmine added another 20,500 ETH through Galaxy Digital.
• July 13: Bitmine acquired 27,801 ETH, bringing its total Ethereum holdings to 5.77 million ETH, according to the official weekly treasury update.
• July 20: Bitmine expanded its Ethereum treasury to 5.78 million ETH after purchasing an additional 7,430 ETH, as reported in the company’s official weekly update.

Not Just a Sector Wide Move

Other crypto treasury stocks were up the same session, but by a smaller margin than BitMine, reported elsewhere as roughly half BitMine’s gain, not independently confirmed by us. That gap is the tell: if this were purely ETH strength lifting every treasury stock together, the spread between names would be narrower. The buyback driven premium appears BitMine specific.

The Analyst Split

The most recent Wall Street rating on BMNR is a Buy with a $25 price target, according to analyst tracking data. A separate AI-generated rating on the same data pegs the stock as Neutral. The gap isn’t unusual for a stock this volatile, but it underscores that the buyback driven ETH per share math doesn’t resolve the underlying disagreement about whether the treasury strategy itself is a sound capital allocation.

What Comes Next

The open question isn’t whether BitMine keeps buying ETH weekly. It has, without a gap, for over a year. It’s whether the buyback can keep absorbing capital at this pace against a cash position now roughly 70% of what it was two weeks ago, and whether next week’s ETH purchase number keeps shrinking as a result. The July 8 and July 10 discrepancy is also worth resolving before the next update, since it bears on how reliable third party on-chain reporting is against BitMine’s own disclosed totals.
