The week was dominated by money. Anthropic’s IPO filing and an expected speculative-grade credit rating, Nvidia’s investment in Meta, Intel’s sharp fall and OpenAI’s reportedly smaller funding round all point to the same question: how long can AI infrastructure spending keep growing at this pace? On the product side, Google staged Gemini 4 Carbon and Mistral released Large 4 with open weights. The week closed with a policy step, as four AI labs agreed to support one shared way for websites to opt out of AI training.
