Jeff Bezos’s AI startup Project Prometheus is nearing a $10 billion funding round at a $38 billion valuation, according to the Financial Times. JPMorgan and BlackRock are lead investors in the round, which has not yet closed. The company’s previous valuation, set during a Series B last summer, was approximately $800 million.

That is a 47x step-up in roughly 10 months.

What Project Prometheus Does

The lab focuses on physical AI — AI systems trained to understand the real world rather than text and images scraped from the public internet. Its stated targets are engineering, manufacturing, automotive, aerospace, robotics, and drug discovery.

The distinction matters for training data. LLMs train on abundant, cheap text. Physical AI systems require proprietary data on material behaviour, engineering tolerances, manufacturing physics, and real-world sensor readings — data that is scarce and hard to replicate. Prometheus has announced a parallel strategy to address this: a separate $100 billion industrial acquisition fund intended to buy and upgrade industrial companies, using those companies both as clients for its AI and as sources of proprietary training data.

The Team

CEO Vikram Bajaj is a former Google X scientist and co-founder of Foresite Labs. The company has grown to over 120 employees drawn from OpenAI, xAI, Meta, and DeepMind. Bezos is an initial investor and has been leading fundraising alongside Bajaj. This is Bezos’s first operational involvement in a technology company since stepping down as Amazon CEO in 2021.

Prometheus launched in November 2025 with $6.2 billion in initial funding.

The Bezos AI Portfolio Diverges

The timing creates an unusual split. The same week Prometheus’s $10 billion raise surfaced, Amazon — the company Bezos founded and still holds a significant stake in — announced a $5 billion additional investment in Anthropic and a 10-year $100 billion AWS compute commitment.

Bezos is therefore simultaneously backing:

• Anthropic (via Amazon), building frontier language models
• Project Prometheus (personally), building physical AI for industry

The bets are not in conflict. Language model capability and physical world understanding are largely orthogonal problems, and the markets they address — cloud services versus industrial automation — are distinct. But the parallel underscores how capital is now flowing into every viable AI wedge simultaneously, regardless of overlap.

Why Institutional Capital Is Here

The involvement of JPMorgan and BlackRock — historically conservative relative to venture and growth funds — signals that physical AI is crossing into the asset class that institutional allocators take seriously.

Physical AI is conceptually harder to invest in than language models: the data is harder to acquire, the markets are less liquid, and the feedback loops are longer. But the potential market (industrial automation, aerospace, pharmaceuticals) dwarfs the software productivity market that LLMs are currently disrupting. BlackRock’s presence in particular may reflect interest in the industrial acquisition fund component — a structure closer to private equity than frontier tech venture.
