Anthropic and a Billion-Dollar Robot Startup Held Talks This Spring. Here Is What We Know.

Key points

• Anthropic and Physical Intelligence, a San Francisco robotics startup valued at roughly $11 billion, held acquisition talks in spring 2025, according to The Information.
• Physical Intelligence has raised more than $1 billion and its AI model for controlling robots, called pi0.5, is widely used in academic robotics research.
• OpenAI is already an investor in Physical Intelligence, which could give it legal rights to block or match any sale to a rival.
• Anthropic confidentially filed for a stock-market debut on 1 June 2026; OpenAI followed one week later.
• OpenAI has acquired at least 17 companies since 2023; Anthropic has made four known acquisitions this year.

Tech blogger Robert Scoble's weekend post on X set AI Twitter alight with a claim that Anthropic was buying Physical Intelligence. Physical Intelligence's CEO Karol Hausman denied it, but the denial, a Slack message to staff containing a gif of a character from "The Office" shaking her head, wasn't exactly a firm rebuttal.

As TechCrunch AI reported, citing The Information, the rumour had roots in reality: the two companies did hold acquisition talks this spring, though nothing closed.

Physical Intelligence was founded roughly two years ago in San Francisco by investor Lachy Groom alongside former Google researchers and Stanford and Berkeley professors. It builds AI software that tells robots how to move and interact with physical objects, essentially a brain for robot arms. Its pi0.5 model lets robots learn tasks from demonstrations rather than hard-coded instructions, and it's become a common tool in research labs. The company has raised more than $1 billion and was reportedly in fresh talks for another $1 billion round at an $11 billion valuation. We first covered Physical Intelligence on 22 July 2026.

Why would an AI lab want a robotics company?

Text on the internet only teaches so much. Researchers increasingly believe AI systems need to understand the physical world, weight and friction, to reach what the field calls superintelligence, meaning AI that matches or exceeds human performance across almost any task. Buying a team that already solves those problems saves years of work.

OpenAI knows this firsthand. It built a robotic hand that could solve a Rubik's Cube, shut the effort down in 2021, then quietly restarted a humanoid robotics lab in San Francisco in 2024. CEO Sam Altman made it official in late May 2025, announcing that OpenAI Robotics was hiring. Anthropic, by contrast, hasn't built anything resembling a hardware lab.

Should Anthropic worry about OpenAI's stake?

OpenAI is already a shareholder in Physical Intelligence. That's not a peripheral detail. Large strategic investors often negotiate rights letting them match a rival's purchase offer or receive advance notice of one. OpenAI didn't respond to questions about whether it holds those rights in this case. But if Physical Intelligence is genuinely for sale, OpenAI arrives with existing shares and its own robotics ambitions, which likely puts it ahead of any outside buyer.

For anyone watching Anthropic's own trajectory, our 15 July 2026 story on Anthropic's enterprise-services company Ode showed a company moving fast to prove it can do more than generate text. A robotics acquisition would be that argument made loudly to prospective public-market investors.

Both companies are preparing their first share sales, and both need to show investors a credible path beyond language models. Robotics is part of that story, and the competition for the firms that know how to build it is already fierce.

One honest takeaway: the real signal here isn't the rumour itself. It's that two companies racing toward stock-market debuts are treating robot-world understanding as table stakes, not a side project. If your work involves physical tasks, which companies buy which robotics firms is worth tracking.
