Bitmine Immersion Technologies shares slid roughly 7.7% in New York on Friday, putting further pressure on one of the largest public Ethereum treasury holdings as ether stumbled. BMNR was changing hands at $20.30 at 15:51 UTC. ETH, the native Ethereum token, hovered around $2,221, down 3.4% for the day.
This shift is key: Bitmine’s pitch to investors hinges less on traditional crypto mining these days, and more on whether the market values holding a sizable pile of ETH on the books. A dip in ether? Suddenly, the stock starts trading less like a mining play and more like a leveraged bet on where ETH heads next.
Bitmine revisited that approach in a May 11 8-K, noting it had published an investor deck, a transcript of a video, and an operations update from Executive Chairman Thomas “Tom” Lee. In the filing, BMNR common shares appear on the New York Stock Exchange, with Norwalk, Connecticut identified as the company’s main executive office.
According to the update, Bitmine reported holdings of 5.2068 million ETH valued at $2,366 each as of May 10—representing 4.31% of the total ETH supply. The company also owns 201 bitcoin, maintains $775 million in cash, and holds stakes worth $200 million in Beast Industries plus $88 million in Eightco Holdings. Lee mentioned Bitmine plans to “slow down our pace” from buying more than 100,000 ETH weekly, noting their previous pace would have put them at the 5% ETH supply mark by mid-July, well ahead of the late 2026 timeline.
Staking makes up the other side of this trade. Essentially, it involves locking up tokens with blockchain validators—those running the network—in exchange for rewards. Bitmine’s approach to ETH staking, the company said, hinges on market conditions, staking returns, custody and security expenses, and capital availability.
Prediction-market participants aren’t locked in on a Bitmine ETH sale as the main scenario, though the chance is in play. On Polymarket’s Ethereum page, the market pricing on a Bitmine Ethereum sale in 2026 sat at 24%. For now, the short-term ETH markets have traders zeroed in around the $2,200 mark.
Peers aren’t standing still. Bit Digital, which is publicly traded and leans on both an Ethereum play and AI infrastructure, reported late Thursday that first-quarter revenue fell 13.6% from the previous quarter, landing at $27.9 million. The company held roughly 155,444 ETH as of March 31. ETH staking revenue slid 29.4% to $2.3 million.
Bit Digital lags Bitmine on the ETH front by a wide margin, yet the contest for investor dollars is clear—everyone pushing treasury heft, staking returns, and the pitch that Ethereum edges nearer to mainstream finance and the AI-driven settlement playbook.
Bitmine is exposed to several newer, trickier-to-price assets through its stake in Eightco. On Thursday, Eightco pegged its portfolio at around $340 million as of May 12. That total includes indirect exposure to OpenAI, equity in Beast Industries, a stash of over 11,000 ETH, Worldcoin tokens, and $129 million in cash and equivalents. Bitmine was also listed among Eightco’s institutional supporters.
The risk here is straightforward. Bitmine’s stock rides on a shaky token, uncertain rules and continued access to capital markets. In its offering documents, the company flagged that a big drop in ETH or bitcoin, trouble at digital-asset platforms, or a regulatory shift could all hit the common shares hard.
Lee maintains that seeing ETH finish the month above $2,100 would signal a shift in the crypto cycle. On Friday, ETH managed to close just over that mark. For BMNR holders, though, the tougher call centers on whether dialing back purchases will be enough to keep the stock afloat if ether hovers around $2,200 instead of moving up.
