Bezos-backed Prometheus hits $41B valuation on $12B raise for physical AI
▼ Summary
– Prometheus, co-led by Jeff Bezos, raised $12 billion at a $41 billion valuation from investors including JPMorgan, Goldman Sachs, and BlackRock.
– The company builds “artificial general engineer” AI tools to accelerate design-to-manufacturing for physical products in industries like aerospace and drug discovery.
– Bezos took an operational role at Prometheus, his first since stepping down as Amazon CEO in 2021, after being impressed by the company’s potential.
– Prometheus focuses on “physical AI,” training models on real-world experimental data and engineering workflows rather than just text or code.
– The company plans to raise tens of billions more for a holding company to acquire firms that benefit from its AI, aiming to become a conglomerate.
Prometheus, the artificial intelligence startup co-founded by Jeff Bezos, has secured $12 billion in new funding, pushing its valuation to $41 billion. The round was backed by financial heavyweights including JPMorgan Chase, Goldman Sachs, BlackRock, DST Global, and Arch Venture Partners, with Bezos himself participating. This latest injection brings the company’s total capital raised to more than $18 billion.
Prometheus is developing what Bezos describes as an “artificial general engineer” , a suite of AI tools meant to dramatically shorten the journey from product design to manufacturing. The technology targets industries such as computing, aerospace, automotive, advanced manufacturing, and drug discovery. Despite the massive war chest, the company operates with a lean team of roughly 150 employees.
Bezos co-leads Prometheus alongside Vik Bajaj, a Stanford medical school professor who previously co-founded Alphabet’s Verily health research lab. Bezos initially joined as a founding investor in late 2024, but his involvement deepened over time. “I became so impressed by what was happening and the potential that I decided I couldn’t sit on the sidelines and I needed to jump in with both feet,” he told CNBC.
This marks Bezos’s first operational role at a technology company since stepping down as Amazon CEO in 2021. Prometheus launched in November 2025 with $6.2 billion in initial funding. Earlier reports had pegged the round at $38 billion, but the final close came in at $41 billion, a 7.9% premium over the April estimate.
The company’s core concept is “physical AI” , models trained not just on text and images, but on real-world experimental data, robotics interactions, and engineering workflows. While most AI firms focus on language or code generation, Prometheus targets the hard science of manufacturing tangible objects, from bridges to microchips. The goal is to build an AI that understands the laws of physics, not just statistical patterns.
Beyond the lab, Prometheus is also seeking to raise tens of billions more for a holding company that would acquire businesses poised to benefit from its technologies. This strategy would transform Prometheus from a pure startup into a conglomerate , one that develops the AI and then buys the companies that deploy it.
Bezos’s broader AI portfolio now includes robotics firms Physical Intelligence and Nvidia-backed Generalist AI, along with his ongoing role as Amazon’s executive chair. With Prometheus, he is placing a massive bet that AI’s greatest value lies not in chatbots or code, but in accelerating the engineering of physical products , the arena where the physical AI race is drawing its largest checks.
