Jeff Bezos’s Prometheus raises $12B to build an ‘artificial general engineer’ for the physical world

Prometheus, the physical AI startup co-founded by Jeff Bezos and Vik Bajaj, has raised $12 billion at a $41 billion valuation, marking one of the largest single bets on AI for the physical world. The funding round, which included investments from Bezos himself, JPMorgan Chase, Goldman Sachs, and BlackRock, comes just months after the company’s initial $6.2 billion raise in late 2024.

What is Prometheus building?

Prometheus is developing what it calls an “artificial general engineer” — software designed to automate the design and manufacturing of complex physical systems, including jet engines, industrial machinery, and drug compounds. The company’s ambition is to replace large portions of traditional engineering work with AI, a shift that could reshape industries reliant on physical product development.

Bezos’s vision for labor and productivity

In an interview with CNBC, Bezos argued that AI-driven productivity gains will lead to what he terms “labor scarcity” — a scenario where demand for human workers outpaces supply. This perspective contrasts with many tech leaders who warn of widespread job displacement. “Significant productivity in the economy is going to raise the standard of living,” Bezos said, predicting that two-earner households may become one-earner households and overtime work could decline.

Bezos’s views carry weight given his role as executive chairman and largest individual shareholder of Amazon, which employs over 1.5 million people and has recently cut tens of thousands of roles amid increased automation.

Why physical AI is attracting massive investment

At $41 billion, Prometheus is one of the most richly valued AI startups ever funded. The company has 150 employees across offices in San Francisco, London, and Zurich. Bezos indicated that a large portion of the new capital will go toward meeting the company’s substantial compute requirements.

The physical AI sector has seen a surge in venture capital interest, with investors arguing that hardware-integrated AI creates stronger competitive moats than pure software. Prometheus is not alone in this space, but its valuation signals growing confidence that AI can meaningfully transform physical engineering and manufacturing.

Conclusion

Prometheus’s record-breaking raise underscores a pivotal moment for physical AI. While the company has yet to publicly disclose specific products or early results, the scale of investor backing suggests high expectations for its “artificial general engineer” vision. The outcome of this bet will have implications for engineering labor markets, industrial automation, and the broader AI investment landscape.

FAQs

Q1: What is an ‘artificial general engineer’?
An artificial general engineer is AI software designed to automate the design, testing, and manufacturing of complex physical systems like engines, machinery, and drugs, potentially replacing many traditional engineering tasks.

Q2: Who are the key investors in Prometheus?
Investors include Jeff Bezos, JPMorgan Chase, Goldman Sachs, and BlackRock, among others. The company raised $12 billion in its second funding round at a $41 billion valuation.

Q3: How does Prometheus differ from other AI startups?
Prometheus focuses on physical AI — applying AI to real-world engineering and manufacturing — rather than purely digital or software-based AI. This sector is seen as more defensible due to the complexity and physical constraints involved.
