Anthropic, OpenAI in robotics race; acquisition talks with Physical Intelligence surface

The Anthropic-Physical Intelligence acquisition rumor, though unconfirmed, illuminates a strategic pivot happening across the AI industry's largest players. Both Anthropic and OpenAI have shifted from pure language models toward embodied AI—systems that interact with the physical world. OpenAI's path is instructive: it built an early robotic hand that solved a Rubik's Cube, then abandoned robotics in 2021 because co-founder Wojciech Zaremba believed the approach was missing pieces needed for superintelligence. That conviction reversed in 2024, when OpenAI quietly built a humanoid robotics lab in San Francisco and made it public in late May. Anthropic's approach has been more cautious; rather than building hardware, it has stress-tested its Claude model's ability to help humans program robots through internal research—notably Project Fetch last November and a June follow-up showing vastly faster task completion.

The timing of these acquisition sprees matters. Both companies filed for IPO within days of each other (Anthropic on June 1, OpenAI a week later), positioning themselves for two of the largest U.S. stock debuts in history. The race to secure robotics expertise and teams—whether through acquisition or internal build—reflects a belief that physical-world understanding is essential to the next phase of AI capability. For investors, the Financial Intelligence stake in both companies underscores how intertwined the AI ecosystem has become and raises questions about whether early strategic investments, like OpenAI's stake in Physical Intelligence, carry protective provisions that could influence future M&A outcomes.
