Anthropic and OpenAI Reportedly Priced at $1.4T and $1.25T as Nvidia's Huang Faces Investigation

Last Week in AI's five-week catch-up reports that Nvidia CEO Jensen Huang is under investigation and that Anthropic and OpenAI have been priced at roughly $1.4 trillion and $1.25 trillion, even as spending reportedly stalls. The newsletter also says Anthropic has warned it may be nearing recursive self-improvement, and it covers a Gemini 4 Carbon release. The description is a brief headline digest, so the underlying details should be checked against primary reporting.

Why it matters: These valuations, the reported slowdown in AI spending, and Anthropic's self-improvement warning bear directly on vendor stability, pricing, and how quickly capabilities may change for teams building on frontier models.
