Palantir stock jumps, Thomson Reuters dives as Anthropic’s legal AI tool spooks software shares

Nvidia shares dropped 2.9% to $185.61 Tuesday morning after reports surfaced that OpenAI is unhappy with some of Nvidia’s newest AI chips and is exploring other options. OpenAI has reportedly looked into chips from Advanced Micro Devices and startups like Cerebras Systems and Groq. The focus is shifting toward “inference”—the real-time output of trained AI models. Nvidia claims its platform leads on inference, offering "the best performance and total cost of ownership at scale." Meanwhile, OpenAI CEO Sam Altman praised Nvidia’s chips as the “best AI chips in the world” and said OpenAI aims to stay a “gigantic customer.”
