Bezos Built AWS to Power the AI Revolution. Now He Is Backing the Architecture That Might Replace It.

Jeff Bezos built Amazon Web Services to run the AI revolution. His newest AI bet may be designed to make that infrastructure irrelevant instead.

Project Prometheus, the secretive manufacturing-AI startup Bezos co-founded in November 2025, is expanding across San Francisco, London, and Zurich — with more than 120 employees hired from OpenAI, DeepMind, Meta, and Google X, according to Observer reporting. The company acquired General Agents, an agentic-AI startup founded by former DeepMind and Tesla researchers, last year, per the same reporting. And it is closing a $10 billion funding round that values it at $38 billion — Business Insider reported the round is still in progress and terms could change before closing.

What makes Prometheus architecturally unusual is not the headcount or the valuation. It is the premise.

Cloud computing — the model Amazon pioneered with AWS, that Microsoft and Google spent billions replicating, that AI labs are now spending $100 billion annually to rent — assumes that AI inference runs in centralized data centers, routed through APIs, priced per unit of output. Physical-world AI, which applies machine learning to robots, materials simulation, and factory automation, breaks that assumption. Systems that need to operate at the edge, close to the physical process, with response times no cloud network can reliably guarantee, do not route through centralized compute. If that architecture wins at scale, the relationship between AI capability and cloud compute demand weakens — and Amazon's most profitable division becomes a middleman rather than an architect.

The paradox for Amazon is immediate: if Prometheus succeeds at building physical AI systems that run on edge inference hardware rather than centralized cloud, the company would depend on infrastructure that competes with AWS — the division that still generates the majority of Amazon's operating income.

Fei-Fei Li's World Labs raised $1 billion for spatial intelligence. Yann LeCun's AMI Labs secured Europe's largest seed round at $1 billion. Periodic Labs, which raised $300 million last year with Bezos as an investor, is building robotic laboratories to train AI on physical experimentation at industrial scale. Physical Intelligence, another Bezos-backed company, released a robotic foundation model last week that demonstrated compositional generalization — the ability to recombine known skills to handle objects it had never explicitly encountered.

Bessemer Venture Partners pegs the global manufacturing market at $17 trillion annually, versus roughly $1 trillion for software — a 17-to-one imbalance that explains why every major AI lab is now looking beyond chatbots.

The key question Prometheus has not answered publicly: whether its models actually run on edge hardware or ultimately depend on cloud infrastructure. Watch for any infrastructure disclosure in its eventual regulatory filings, or for AWS to signal how it views the threat in its next earnings call.

Prometheus did not respond to a request for comment. A company spokesperson declined to comment on the funding round.
