Overview
<cite index="18-2">Prometheus, the physical AI (Artificial Intelligence) startup co-founded by Jeff Bezos and Vik Bajaj, the former co-founder of Verily, Google's life sciences unit, announced it raised $12 billion at a $41 billion valuation.</cite> <cite index="3-3">The two co-CEOs appeared together publicly for the first time in a CNBC interview at the startup's San Francisco headquarters on June 11, 2026.</cite>
Funding Structure and Investors
<cite index="10-3">The round was led by JPMorgan Chase, Goldman Sachs, and BlackRock, with participation from DST Global, Arch Venture Partners, and Bezos himself.</cite> <cite index="15-6">Bezos was the largest backer of the company's $6.2 billion Series A at launch in November 2025 and contributed again in this round.</cite> <cite index="10-4">The financing brings Prometheus' total capital raised past $18 billion, just seven months after the company emerged from stealth in November 2025 with a $6.2 billion debut round.</cite>
<cite index="6-4,6-5">Earlier reporting had valued the round at $38 billion; the final close came in at $41 billion, a 7.9% markup from the figure reported in April.</cite>
Mission and Product Direction
<cite index="18-5">Prometheus is building what it calls an "artificial general engineer" — software capable of automating the design and manufacturing of complex physical systems, from jet engines to drug compounds.</cite> <cite index="6-6,6-7">The company's pitch is "physical AI": models trained on real-world experimental data, robotics interactions, and engineering workflows rather than just text and images, targeting the hard science of making things, from bridges to chips.</cite> <cite index="6-16">Target industries include computing, aerospace, automotive, advanced manufacturing, and drug discovery.</cite>
<cite index="17-5">This approach requires systems that can learn not just from massive amounts of digital data, as LLMs (Large Language Models) are programmed to do, but also from real-world trial and error.</cite>
Use of Capital
<cite index="15-7">A significant portion of the capital is earmarked for compute — the company's training requirements rival those of the world's largest frontier AI labs.</cite> <cite index="1-7">Prometheus currently sources compute from multiple providers.</cite> <cite index="1-6">Bezos indicated that Prometheus could become a customer of Amazon Web Services as the company seeks additional compute capacity, though he noted the two companies would remain at arm's length.</cite>
Team and Infrastructure Build-Out
<cite index="5-3">Prometheus currently has around 150 employees.</cite> <cite index="20-7">The Financial Times reports the venture has recruited across San Francisco, London, and Zurich, targeting engineers, AI researchers, and large-scale infrastructure specialists.</cite> <cite index="1-3">The company has recruited talent from companies including OpenAI, Google DeepMind, and Nvidia.</cite>
A notable infrastructure hire preceded the Series B close. <cite index="19-3">Kyle Kosic, who previously led the infrastructure team for xAI's Colossus supercomputer and held a role at OpenAI, is expected to spearhead AI infrastructure projects at Prometheus.</cite>
Corporate Independence and Broader Strategy
<cite index="5-4,5-5">Prometheus does not have corporate ties to either Amazon or Blue Origin, with Bezos saying it "deserves a dedicated team that is obsessed with this one thing," though he called Blue Origin a "case study for a customer of Prometheus."</cite>
<cite index="17-8">As of 2026, the Prometheus group is also seeking large-scale funding for a holding company that would acquire companies that Bezos and Bajaj anticipate will be hit by industrial AI technology.</cite>
Market Context
<cite index="7-7">Prometheus' rapid scaling — from a $6.2 billion debut to a $41 billion valuation in seven months — underscores the intense competition in AI infrastructure and the appetite among institutional investors for startups tackling physical-world automation.</cite> <cite index="8-9">The company is roughly seven months old, has around 150 employees, and is already valued near Autodesk, a decades-old public engineering software company with more than $7 billion of annual revenue.</cite>
