Prometheus, the artificial intelligence startup co-led by Amazon founder Jeff Bezos and Stanford professor Vik Bajaj, has raised $12 billion in Series B funding at a $41 billion valuation, according to comments made by Bezos during an interview with CNBC.
The funding follows the company’s launch in November 2025 with $6.2 billion in financing. Prometheus is focused on developing AI models for physical tasks, including engineering, manufacturing, and drug design, and has recruited talent from companies including OpenAI, Google DeepMind, and Nvidia.
Bezos, who stepped down as Amazon CEO in 2021 and now serves as executive chairman, said the company is working to create what he described as an “artificial general engineer” designed to accelerate the invention process and make it easier for engineers to design physical products.
The latest funding round will primarily be used to secure additional computing resources, which Bezos said are essential because of the computational intensity of the company’s work. Prometheus currently employs about 150 people and operates out of San Francisco, London, and Zurich.
Bezos emphasized that the company is not developing robots, contrary to speculation, and said Prometheus is focused on creating AI-powered engineering tools. He added that while it remains early to discuss the company’s accomplishments, the progress made so far has been “quite remarkable.”
Bezos also indicated that Prometheus could become a customer of Amazon Web Services as the company seeks additional compute capacity, although he noted the two companies would remain at arm’s length. Prometheus currently sources compute from multiple providers.
In discussing AI more broadly, Bezos said he believes the technology will significantly boost productivity and raise living standards. He also expressed support for “reasonable” regulation focused on AI applications rather than the underlying technology.
