Bezos’ Project Prometheus Nears $38B Valuation

Project Prometheus is nearing a $38 billion valuation after lining up about $10 billion from JPMorgan, BlackRock and other investors to fund a physical artificial intelligence laboratory. The new financing is expected to close soon. Prometheus raised $6.2 billion in seed capital at launch in November 2025, including investment from Jeff Bezos, and demand from institutional investors prompted an extension of the round to take in roughly $10 billion more.

Prometheus is set up as a physical AI laboratory that aims to build systems that understand physical laws and interact with physical environments, with a focus on manufacturing and industrial processes. Those systems rely on real-world interaction data such as sensor readings, tactile feedback, motion trajectories and records of failures.

Collecting that data is costly and often proprietary. Tesla is a frequently cited example of a data advantage: the automaker reportedly has between 5 million and 6 million vehicles with advanced driving hardware that generate more than 50 billion miles of driving data each year.

Prometheus plans to address the data challenge by operating through a holding company that will acquire engineering, architecture and design firms to produce operational data for training and validating its AI systems. Bezos and Prometheus co-chief executive Vikram Bajaj are holding separate talks to raise tens of billions of dollars for the holding company. Arch’s director Nelsen described Prometheus as “one of the most important companies in the world.”

The lab is in an early phase but has recruited more than 100 employees drawn from firms including Meta, OpenAI and DeepMind. Bezos and Bajaj are overseeing both the lab’s technical work and the broader acquisition strategy.

Separately, Amazon has invested an additional $5 billion in Anthropic, with an option to commit up to $20 billion over time. As part of that arrangement, Anthropic has agreed to spend more than $100 billion on Amazon Web Services technologies over the next decade.
