Crypto Treasury Stocks Slide: BitMine (BMNR) and Strategy (MSTR) Drop Nearly 10% as BTC and ETH Retreat

When crypto sells off, the equities tied to it often move faster. Thursday was a clean reminder. Shares of BitMine Immersion Technologies (BMNR) and Strategy (MSTR) both fell nearly 10% as Bitcoin and Ethereum retreated into two‑month territory, with Washington brinkmanship and big‑tech nerves souring risk appetite.

BMNR closed at $26.70 after touching $26.02 intraday—matching its November 2, 2025 close of $26.02. Strategy finished at $143.19 after slipping to $139.36, its lowest print since September 2024, per Yahoo Finance. The macro tape did little to help: the U.S. Senate blocked a continuing resolution Thursday afternoon, raising the odds of a partial government shutdown if lawmakers don’t clinch a deal by Saturday. Microsoft’s slump added to latent “AI bubble” worry, weakening the bid for high‑beta names.

Under the surface, this is less about headlines and more about reflexivity in public crypto treasuries. These businesses are effectively balance‑sheet wrappers around BTC and ETH, so mark‑to‑market swings feed straight into equity volatility. That convexity cuts both ways.

- BitMine’s accumulation continued this week: Tom Lee’s firm executed its largest 2026 buy—$116 million of ETH—after prior purchases of $108 million, $76 million, and $100 million earlier this year. Its Ethereum treasury now sits near $11.9 billion, roughly 3.5% of ETH’s total supply, according to a CoinGecko‑tracked dashboard. That concentration provides scarcity optics when the market is rising, but it also heightens single‑entity governance and liquidity questions on drawdowns. If investors begin to price in potential supply overhang or treasury‑management rigidity, equity multiples tend to compress faster than the underlying token.

- Strategy disclosed another $267 million of Bitcoin bought last week. Its holdings stand at 712,647 BTC—valued around $60 billion at prevailing prices. The company co‑founded by Michael Saylor has turned treasury policy into its core product, and the stock often trades as levered BTC beta. During macro stress—shutdown chatter, tighter financial conditions, or factor rotations out of tech—the leverage premium can invert into a discount.

Spot moves set the tone. Bitcoin fell more than 5% on the day, recently changing hands near $84,416 after rebounding from an intraday low at $83,407. That’s still above late‑November levels, when BTC briefly slipped below $83,000 following a $1.3 billion dump by a billionaire holder. Ethereum slid to $2,816, down about 6.6% over 24 hours, per CoinGecko.

Forward expectations are adjusting. On Myriad—a prediction market platform owned by Dastan—traders increased the probability that ETH tags $2,500 before reclaiming $4,000 from 65% to above 75% on Thursday. Markets are expressing a preference for defensive positioning until policy noise clears.

What matters next is treasury signaling. Continued net buying into weakness can anchor perceptions of a floor, but it can also amplify equity drawdowns if investors worry about duration risk and funding flexibility. The market tends to reward disciplined, rules‑based allocation frameworks that reduce discretionary timing risk. In a week where shutdown risk and tech‑factor fragility collided, the lesson is familiar: crypto‑heavy balance sheets offer torque, not insulation. Pricing that nuance correctly is the edge.
