TechCrunch reports that Prometheus, the physical AI startup co-founded by Jeff Bezos and Vik Bajaj, has raised $12 billion at a $41 billion valuation. The round was backed by JPMorgan Chase, Goldman Sachs, and BlackRock, among others. Prometheus describes itself as building an 'artificial general engineer' — software designed to automate the design and manufacture of complex physical systems, from jet engines to drug compounds. The new raise follows Prometheus's initial $6.2 billion launch round and makes it one of the most richly valued AI startups ever funded. While the term 'AGI' is usually attached to software reasoning, Prometheus is betting that the next frontier is AI that can engineer the physical world — buildings, medicines, and machines included.
