Anthropic held acquisition discussions with Physical Intelligence, a robotics startup valued at $11 billion, earlier this year, according to reporting that emerged this week. While Physical Intelligence's CEO Karol Hausman denied a deal through a lighthearted Slack message, the underlying dynamic reveals something crucial about the next phase of the AI race: the companies building the most powerful language models now believe they need to own robotics expertise to stay competitive.

Why Are OpenAI and Anthropic Suddenly Focused on Robotics?

The robotics question cuts to the heart of how AI labs think about the future. Physical-world understanding may be essential for the kinds of general-purpose AI systems both OpenAI and Anthropic say they want to build. No amount of internet text data can substitute for real experience with robots, hardware, and the messy unpredictability of the physical world. Acquiring an existing robotics team would let either company skip years of hardware iteration and dataset collection.

OpenAI's own history illustrates just how difficult this is. The company built an early robotic hand that solved a Rubik's Cube, then shut down its entire robotics group in 2021. Co-founder Wojciech Zaremba later explained the decision, noting that "the approach was missing pieces needed for real superintelligence." The team quietly returned in 2024, building a humanoid robotics lab in San Francisco. In late May, Sam Altman made OpenAI Robotics official, describing a near-term focus on robots for infrastructure work and a long-term goal of a personal robot for everyone.

Anthropic has taken a different path. Rather than building hardware from scratch, it has run robotics through its safety-research group. Project Fetch, announced last November, tested how much Claude could help non-experts program a robot dog. A second phase in June found that a newer Claude model completed the same tasks roughly 20 times faster than the best human-plus-Claude team from the year before. The results are impressive on paper but do not amount to a robotics business, which is why an acquisition of a company like Physical Intelligence would make strategic sense.

What Makes Physical Intelligence So Valuable?

Physical Intelligence has raised more than $1 billion since its founding roughly two years ago and was reportedly in talks this spring for another $1 billion round at the $11 billion valuation. Its pi0.5 model is among the more widely used robot brains in academic robotics research. The company was co-founded by investor-operator Lachy Groom alongside former Google researchers and professors from Stanford and Berkeley.

The startup's investor base reveals why it matters so much to both AI labs. Physical Intelligence's early backers include Khosla Ventures, Thrive Capital, and Founders Fund. Those same investors are major backers of OpenAI. In fact, OpenAI itself is already an investor in Physical Intelligence, which creates a complicated dynamic: OpenAI is not a peripheral observer here but a shareholder in a company its chief rival was reportedly negotiating to buy.

How to Understand the Strategic Stakes in AI Robotics

• Shareholder Complications: OpenAI holds equity in Physical Intelligence and may have information rights or rights of first refusal over sales to competitors, giving it leverage in any negotiation with Anthropic.
• IPO Timing Pressure: Anthropic filed confidentially for an IPO on June 1, 2026, and OpenAI filed a week later on June 8, sharpening every strategic decision each company makes before pricing and public markets scrutiny.
• Acquisition Velocity: Anthropic has made four known acquisitions in 2026, while OpenAI has bought at least 17 companies since 2023, showing how aggressively both are consolidating talent and technology.

Whether OpenAI holds such provisions in Physical Intelligence is unclear, and the company did not respond to questions about it. But the underlying dynamic matters more than any single deal. A company with a leading robotics model, deep ties to Silicon Valley's most powerful investors, and an $11 billion valuation is being circled by the two labs racing to define what a general-purpose AI system looks like.

Physical Intelligence's CEO's denial came in gif form rather than a categorical statement, which is telling. The weekend rumor exposed how much of the next phase of the AI race will be settled not by benchmark scores but by which companies can attach physical-world capability onto their models fastest and who they have to outbid or out-negotiate to do it.

If Physical Intelligence is actually in play, OpenAI has the more obvious claim on paper: it is already a shareholder, already close to Groom, and already building a robotics organization that would absorb the team more cleanly. For Anthropic, coming from behind on hardware, the strategic logic of an acquisition is stronger but the execution is harder, especially with a competitor holding equity. Either way, the race for robotics talent is now openly competitive, and the stakes are higher than ever.
