How the Rumor Started
Tech blogger Robert Scoble posted speculation about the deal on X, and the post gained traction quickly. Physical Intelligence is far from an obscure entity. The company was co-founded by rising Silicon Valley investor-operator Lachy Groom and has reportedly raised over $1 billion. Its π0.5 model is also widely used in robotics research.
The Denial That Wasn’t Quite a Denial
The initial rumor was denied, but not entirely baseless. According to The Information, Anthropic and Physical Intelligence did hold acquisition talks earlier this spring. CEO Karol Hausman reportedly dismissed the reports to employees via Slack with a GIF, a response that was less than emphatic. Groom did not comment to TechCrunch.
Why Robotics Matters for AI Leaders
The pursuit of robotics expertise by leading AI firms reflects a growing conviction that physical-world understanding is essential for developing more capable AI systems. Internet text alone cannot provide this foundational knowledge.
OpenAI’s robotics pivot: The company initially shut down its robotics group in 2021, only to revive it in 2024. CEO Sam Altman announced a focus on humanoid robots for infrastructure work.
Anthropic’s robotics work: The company has explored robotics through Project Fetch, where its Claude model assisted in programming a robot dog with significant performance improvements across iterations.
The OpenAI Complication
Any potential Anthropic acquisition of Physical Intelligence faces a major obstacle: OpenAI is already an investor in the robotics company. This creates a strategic conflict that could impact a deal.
| Factor | Implication |
|---|---|
| OpenAI investor status | May hold information rights or right of first refusal |
| Shared investor base | Physical Intelligence backed by Khosla Ventures and Thrive Capital, firms that also backed OpenAI |
| Competitive relationship | OpenAI and Anthropic are direct rivals in generative AI |
OpenAI has not responded to inquiries about whether it holds information rights or a right of first refusal that could impact a sale to a competitor like Anthropic.
The Broader Acquisition Race
This rumor unfolds against a backdrop of aggressive M&A activity in AI:
- Anthropic has completed four acquisitions in 2026
- OpenAI has acquired at least 17 companies since 2023
- Both companies are preparing for what could be historic IPOs (Anthropic filed confidentially on June 1, OpenAI a week later)
The Real Question
Given OpenAI’s existing investment and close ties to Physical Intelligence, does it have a stronger claim to the robotics startup than its rival? The answer will likely determine whether Anthropic pursues a different robotics partner or abandons the space entirely. Either way, the market is watching.
