A weekend rumour that Anthropic was acquiring robotics startup Physical Intelligence spread rapidly on social media, sparked by a post from tech blogger Robert Scoble, despite a denial from Physical Intelligence's chief executive. The story matters because it turned out not to be entirely baseless: according to The Information, Anthropic and Physical Intelligence did hold acquisition talks this spring, suggesting Scoble had the underlying facts right even if the timing or details were off, and highlighting growing interest among leading AI labs in acquiring physical-world robotics expertise.

Physical Intelligence, co-founded by investor-operator Lachy Groom around two years ago with former Google researchers and Stanford and Berkeley academics, has raised over $1 billion and was reportedly seeking another $1 billion round at an $11 billion valuation; its π0.5 model is widely used in robotics research. CEO Karol Hausman denied the reports to staff only via a Slack gif, and Groom did not respond to requests for comment. The episode comes amid a broader wave of AI acquisitions, with Anthropic making four known deals this year against OpenAI's 17 since 2023, and both companies simultaneously preparing for IPOs, having filed confidentially in June. Analysts suggest robotics interest reflects a belief that physical-world understanding is essential for superintelligent systems, a lesson OpenAI learned after abandoning and later reviving its own robotics efforts.
