Bezos Raises $12 Billion for AI Startup Prometheus, Now Valued at $41 Billion

Jeff Bezos and co-CEO Vik Bajaj revealed on Thursday that their industrial AI startup, Project Prometheus, has closed a $12 billion Series B funding round valuing the company at approximately $41 billion — making it one of the largest and fastest fundraises in startup history.cnbc

An ‘Artificial General Engineer’

Prometheus, which emerged from stealth on Thursday after months of speculation, is building what Bezos calls an “artificial general engineer” — AI systems designed to accelerate the design and manufacture of complex physical products such as jet engines, medical devices, and consumer electronics.geekwire

“We’re creating tools that will simplify the process for engineers to design physical objects,” Bezos told CNBC in an exclusive interview, likening the system to “a very, very modern version” of computer-aided design software while cautioning that he was “really oversimplifying.”cnbc

The round was backed by JPMorgan, BlackRock, Goldman Sachs, DST Global, and Arch Venture Partners, bringing total capital raised to $18.2 billion since the company’s launch in November 2025. Bezos himself was the largest individual backer.siliconrepublic

From Secrecy to Scale

Prometheus launched in November 2025 with $6.2 billion in initial funding — already among the largest seed rounds ever — with Bezos and Bajaj, a former Google X executive and Stanford adjunct professor, serving as co-CEOs. The company had initially drawn widespread speculation that it was focused on robotics, a characterization Bezos firmly rejected.business-standard

“We have nothing to do with robotics,” Bezos said in a May interview, describing instead a focus on “AI for the physical economy.”geekwire

Operating from offices in San Francisco, London, and Zurich, Prometheus has hired roughly 120 employees drawn from organizations including OpenAI, DeepMind, and Meta.cnbc

Broader Ambitions

Bezos has also held preliminary discussions with Middle Eastern and Southeast Asian investors about raising up to $100 billion for a separate fund aimed at acquiring industrial companies that could benefit from Prometheus’s technology, according to The New York Times. The tools Prometheus is building “will help companies like Blue immensely,” Bezos said, referring to his space venture Blue Origin.inc
