AI is confronting a supply-chain crunch

Hyperscaler capex grew 190% from 2024 to 2026; their hardware suppliers grew 45%. That gap is why every throttling notice, plan change, and Sora shutdown traces back to the same constraint. The less-discussed dimension: agentic systems need 1 CPU per GPU versus 1:12 for chatbots, which is why Intel has doubled in six months and why every agent platform deck needs a CPU supply slide.

Memory chip stocks shed $100bn as AI-driven shortage trade unwinds

A single Google Research paper on model compression wiped $100 billion from memory chip stocks in five days. Micron dropped 15%; SanDisk, the best S&P 500 performer in 2025, shed $15 billion in market cap. Morgan Stanley's defense was textbook Jevons: efficiency expands demand. But the market just revealed a new risk class: AI efficiency research as a first-order investment catalyst. The next compression paper is already being written; the question is whether you see it before or after the sell-off.
