Jeff Bezos’ AI lab, code-named Project Prometheus, is close to finalizing a $10 billion funding round at a $38 billion post-money valuation, the Financial Times reported on April 21. JPMorgan and BlackRock are among the lead investors. The round has not formally closed.
What Project Prometheus Is Building
Unlike the major AI labs competing on language models and chatbots, Prometheus is focused on AI systems that understand the physical world. According to Business Insider, the company targets real-world industrial processes: manufacturing, aerospace engineering, semiconductor production, and robotics. The core technical challenge is building models that learn through interaction with physical environments rather than training on internet text.
The company launched in November 2025 with $6.2 billion in initial funding, making this $10 billion round its second raise in roughly five months. Co-CEO Vikram Bajaj, a former Google X scientist and adjunct professor at Stanford’s School of Medicine, leads the company alongside Bezos, who holds an operational role for the first time since leaving Amazon in 2021.
120+ Employees, Aggressive Hiring
Prometheus has scaled to over 120 employees drawn from OpenAI, xAI, Meta, and Google DeepMind, according to Crypto Briefing. The company has been expanding office space in San Francisco and recruiting senior researchers from competing labs.
The $100 Billion Holding Company
Separately, Bezos is in discussions to raise up to $100 billion for a dedicated investment holding company, the Wall Street Journal reported last month. That entity would acquire majority or minority stakes in architecture, engineering, and construction firms susceptible to AI disruption, then feed proprietary data from those portfolio businesses back into Prometheus’s models. The strategy creates a data flywheel: acquire companies with decades of physical-world data, use it to train better models, deploy those models back into the acquired businesses.
Scale of the Bet
If completed, the $10 billion round would make Prometheus one of the most richly valued early-stage startups in the world. For context, AI startups attracted $242 billion in venture capital during Q1 2026 alone, representing roughly 80% of all global venture funding, according to Crunchbase data cited by Crypto Briefing. The global AI-in-manufacturing market stood at around $34 billion in 2025 and is projected to reach $155 billion by 2030.
The $38 billion valuation prices Prometheus above most enterprise AI startups and below the frontier language model labs (OpenAI at $300B+, Anthropic at $61.5B). The gap reflects both Prometheus’s earlier stage and the market’s uncertainty about how quickly physical-world AI can match the commercial velocity of language models.
