Bitmine Immersion Technologies stock price: BMNR ticks up in premarket after 10% surge as ether firms

Bitmine Immersion Technologies stock price: BMNR ticks up in premarket after 10% surge as ether firms

New York, Feb 26, 2026, 07:32 EST — Premarket

  • BMNR added another 0.1% premarket, building on its 10.6% jump from the previous session.
  • Ether rises, boosting crypto-linked stocks that traders treat as liquid proxies.
  • Attention shifts to Friday, with U.S. inflation figures and the upcoming crypto-holdings update in focus.

Bitmine Immersion Technologies (BMNR) ticked up 0.1% to $21.53 before the bell on Thursday, building on Wednesday’s 10.6% jump that took shares to $21.50 at the close.

Why does it matter? BMNR’s price action lately has echoed ether more than your typical small-cap. It’s basically been behaving like an equity play on Ethereum’s token. Swings in crypto risk? They usually hit BMNR quickly.

Traders are back to zeroing in on a select group of liquid, high-volatility names as the open approaches, using them to bet on crypto trends—without ever handling tokens themselves.

Ether climbed roughly 6.7% to trade at $2,067. Bitcoin gained as well, up about 3.8% at $68,276.

BMNR kicked off Wednesday at $20.50, traded as high as $22.17 and dipped to $20.49 before the bell rang. Volume hit roughly 60.1 million shares.

Bitmine mines bitcoin using immersion cooling, dunking its machines in a custom fluid to handle heat. Reuters company data shows the firm is also in the business of selling equipment and hosting.

The company reported in a Feb. 23 update that as of Feb. 22, its crypto and cash holdings stood at $9.6 billion, with 4.422 million ether and $691 million in cash. Chairman Thomas “Tom” Lee said, “In the past week, we acquired 51,162 ETH.” The company also revealed it had staked 3.04 million ether, locking up the tokens to validate the network for potential rewards. Its MAVAN platform remains on schedule to launch in the first quarter. PR Newswire

Investors have been pairing BMNR with crypto-treasury plays like Strategy, wagering that these stocks will amplify the swings of their underlying tokens. That trade holds—right up until it doesn’t.

Leverage, though, doesn’t always work in your favor. Should ether lose steam, BMNR could tumble fast. After-hours sessions often see sharper moves too, with lighter liquidity and wider bid-ask spreads fueling volatility.

Eyes shift to Friday, Feb. 27, when the U.S. producer price index drops at 8:30 a.m. ET—numbers that can sway rate bets and ripple through risk assets like crypto-related stocks.
