ACX November 2026 Links: NVIDIA-Hugging Face, AI Forecasts
Scott Alexander's November 2026 links post covers varied topics, including a forecast of a 25% chance of rogue AI weight exfiltration by Sentinel, a predicted rainy California winter with ARkStorm risk, and commentary on AI progress forecasting. Notably, it mentions NVIDIA's acquisition of Hugging Face for $12.9303 billion, an easter egg referencing the hugging face emoji's Unicode code point. The post also discusses Nick Cammarata's claim that 'Neural Networks Are Already Clean', debates on genetics and IQ, and other cultural and scientific curiosities. However, the primary content is a roundup of disparate links, not a single corporate announcement.

Jim Cramer: AI stocks difficult to value amid data center uncertainty
CNBC's Jim Cramer said that uncertainty over the future data center build-out has made AI stocks increasingly difficult to value, leading to steep selling in the sector. He highlighted Nvidia, Micron, and AMD as examples of companies with strong results but facing risks if AI infrastructure spending slows due to regulatory hurdles. The iShares Semiconductor ETF fell 3% Wednesday and 10% Thursday, while GE Vernova and Sandisk dropped 7% and 22% respectively. Cramer noted Nvidia trades at roughly 12 times next year's earnings with 70% expected growth, but questioned sustainability if data center construction slows. He also questioned the sturdiness of Micron's take-or-pay contracts and AMD's valuation despite strong earnings and CEO Lisa Su's projection of a $1 trillion data center market. Ultimately, the key question is whether regulatory hurdles will significantly slow or merely delay data center construction.

Revenue rose 66% to $228 million, beating estimates, with AI Cloud revenue doubling to $200 million.

IREN's backlog grew 22% to $20.3 billion, with planned capital expenditures of $15 billion this fiscal year. The company also expanded a contract with a leading frontier AI lab.
