Rumors regarding a potential acquisition of the robotics startup Physical Intelligence by Anthropic circulated widely on X over the weekend of July 21, 2026. While the reports triggered significant industry attention, Physical Intelligence CEO Karol Hausman reportedly denied the acquisition to employees via a Slack message. Records indicate that Anthropic and Physical Intelligence did conduct acquisition discussions earlier this spring, though no deal has been finalized.

Physical Intelligence has gained attention for its π0.5 model, widely utilized in robotics research, and its substantial funding, having raised over $1 billion with reports of a recent round targeting an $11 billion valuation. The startup was founded approximately two years ago in San Francisco by Lachy Groom, former Google researchers, and academics from Stanford and Berkeley. Its investor base includes notable firms such as Khosla Ventures, Thrive Capital, and Founders Fund.

The interest in robotics among leading AI firms reflects a strategic shift toward physical-world understanding, which researchers view as a requirement for developing superintelligent systems. OpenAI, which has acquired at least 17 companies since 2023, maintains its own robotics lab and recently formalized 'OpenAI Robotics' under CEO Sam Altman. Conversely, Anthropic has focused its robotics efforts on research, including 'Project Fetch,' which demonstrated that newer models could complete robot-programming tasks roughly 20 times faster than human-assisted teams from the previous year.

Complicating potential acquisition scenarios is the fact that OpenAI is an existing investor in Physical Intelligence. Industry observers have raised questions regarding whether OpenAI holds protective provisions, such as a right of first refusal, that could prevent a rival like Anthropic from completing a purchase. As both Anthropic and OpenAI move toward public offerings—having filed for IPOs on June 1 and June 8, 2026, respectively—the competition for robotics talent and technology remains a focal point for their respective enterprise strategies.
