Prometheus, the physical AI startup co-led by Jeff Bezos and Vik Bajaj, has raised $12 billion at a roughly $41 billion valuation, according to multiple reports published after the company's first major public comments.

The round is unusually large even by current AI funding standards. Reported backers include Bezos, JPMorgan Chase, Goldman Sachs, BlackRock, DST Global, and Arch Venture Partners. Prometheus previously launched with $6.2 billion in initial funding, putting total disclosed capital above $18 billion.

Prometheus is not pitching a chatbot or a factory robot. Its stated aim is to build what Bezos has called an "artificial general engineer": AI tools that can help design, simulate, and move physical products toward manufacturing. Reported target areas include aerospace, automotive systems, computing hardware, advanced manufacturing, and drug discovery.

The company is still keeping product details limited. TechCrunch reported that Prometheus has about 150 employees across San Francisco, London, and Zurich, while GeekWire reported that Bezos and Bajaj discussed the company's compute and specialized training-data needs in a CNBC interview.

Why It Matters

The new round makes Prometheus one of the clearest examples of AI capital moving from software workflows into physical industry. The bet is that models trained on engineering processes, experiments, and manufacturing constraints can shorten design cycles for complex products.

That remains an expensive and unproven claim. But the scale of the financing gives Prometheus enough runway to test whether "physical AI" can become more than a label for industrial automation.
