Bezos’s $41B Prometheus Raises $12B to Build AI That Designs Jet Engines “10 Times Faster” — and Says Jobs Will Grow

Jeff Bezos stepped back from running Amazon in 2021. Now he is running a new company — and this time, his target is engineering itself. Prometheus, the physical AI startup Bezos co-founded with scientist Vik Bajaj in late 2024, closed a $12 billion Series B round on June 11, 2026, valuing the company at $41 billion. The goal: build what Bezos calls an artificial general engineer — an AI that can design, simulate and manufacture complex physical products far faster than any human team working today. From jet engines to drug compounds to semiconductor chips, Prometheus is betting that the next wave of AI won’t live in a chat window. It will live on the factory floor.

What Prometheus Is Building

The “Artificial General Engineer” — Explained Simply

🏗️
Design
AI tools that help engineers design physical products — from circuit boards to aircraft components — faster than traditional CAD and simulation workflows.
🔬
Simulate
Models trained on real-world engineering data, not just text. They learn how materials behave, how systems fail, and what combinations actually work — before anything is physically built.
⚙️
Manufacture
Once a design is validated, AI accelerates the path to production. Prometheus targets the full cycle: from first sketch to mass manufacturing, with fewer iteration loops.
🚀
Compress Time
A new jet engine can take 10+ years and thousands of engineers to develop today. Prometheus’s stated aim is to make that loop ten times faster — or more.

Prometheus is not building chatbots. In a May 2026 CNBC interview, Bezos was direct: “We have nothing to do with robotics.” The company describes its product as a modern, deeply capable version of computer-aided design (CAD) — one that learns from experimental data and engineering workflows the way language models learned from text. Think of it as the difference between a model that can write a recipe and one that can actually cook. Bezos has been working on this concept since late 2024, and counts Blue Origin — his own rocket company — as a future customer.

AI’s reach into enterprise workflows is accelerating across sectors. Prometheus is operating on the physical side of that shift — moving beyond software into the industries that make things.

Funding Timeline

From Zero to $41 Billion in Under Two Years

Prometheus launched in stealth in late 2024. Its two funding rounds have made it one of the most valuable private AI companies ever. Tap each milestone to expand details.

Target Industries

Where the “Artificial General Engineer” Will Work

Prometheus has not released a product roadmap publicly, but Bezos and Bajaj have named specific sectors where they see engineering cycles as too slow and too costly.

In Their Own Words

What Bezos and Bajaj Said

All societal wealth is driven by invention. Six thousand years ago, somebody invented the plough, and we all got wealthier. Then, much later, somebody invented the steam engine, and we all got wealthier. What Prometheus seeks to do is to offer a set of tools that dramatically accelerates that invention loop.
Jeff Bezos — Co-CEO, Prometheus · CNBC Interview, June 2026
I think we’re actually going to have labour scarcity. When productivity rises that much, the basket of goods people can afford becomes larger relative to the amount they need to work.
Jeff Bezos — Co-CEO, Prometheus · CNBC Interview, June 2026
What creates jobs? Companies occasionally create jobs, but what really creates jobs is invention. We will create more engineers. We will have more jobs in engineering and manufacturing as a result of inventing more.
Vik Bajaj — Co-CEO, Prometheus · CNBC Interview, June 2026
The pace of our physical creation right now is nowhere near the pace of human imagination.

The Jobs Question

Bezos vs. the Displacement Debate

A large part of the Prometheus story involves a debate playing out across the entire AI sector: will automation create or eliminate jobs? Bezos’s position is clear. He believes productivity gains from AI will lead to what he calls “labour scarcity” — where demand for human workers outpaces supply, rather than the reverse. He compared the moment to historic technological shifts, from the plough to solar cells to penicillin, arguing that those inventions spread through society and raised living standards over time.

Other major AI players have framed their models in more cautious terms on the employment question. Bezos explicitly pushed back: “I know why people are pessimistic. They’re pessimistic because a lot of smart people are telling them to be pessimistic. But those people are wrong.”

Bajaj added that faster invention creates new industries and new professions — rather than automating existing ones away. Prometheus has not published a formal economic analysis, and the technology itself remains in early development. Amazon, where Bezos serves as executive chairman, employs more than 1.5 million people globally and has been accelerating automation under CEO Andy Jassy. Bezos acknowledged this directly, noting that AI-driven productivity could shift which types of work people do, rather than simply removing them from the workforce.

Prometheus’s $41 billion valuation and $18.2 billion in total funding were covered across this piece, along with the company’s stated goal of building an artificial general engineer for physical industries. Jeff Bezos’s and Vik Bajaj’s positions on AI and labour markets were discussed, as were the industries Prometheus has named as targets — from aerospace to drug development. The company’s funding rounds, investor composition and early technical direction were also covered. Prometheus has not publicly disclosed a product, and Bezos described the company’s progress as “premature” to detail, adding that it is “really quite remarkable.” Further reporting on physical AI and the broader sector can be found at Giganectar’s Prometheus coverage.
