Meta Strikes Multibillion-Dollar Deal to Use Amazon Chips for AI Projects

Meta is renting hundreds of thousands of Graviton chips from AWS for multiple billions; Graviton is a CPU, not an accelerator. The consensus is measuring AI capex by GPU count, but at production scale the CPU layer, which handles feature serving, retrieval, ranking, and orchestration, runs roughly 5-10x the accelerator unit count. This deal is the first explicit public signal that reframes general-purpose CPU compute as a distinct AI infrastructure category, and it means the total AI infrastructure commitment envelope is materially larger than accelerator-only framings capture.

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.
