Bezos-backed Prometheus raises $12B at $41B valuation

What happened

Prometheus, the physical-AI startup co-founded by Jeff Bezos and Vik Bajaj (ex-Verily), announced on June 11, 2026 a $12B round at a $41B valuation. Lead investors are Bezos, JPMorgan Chase, Goldman Sachs and BlackRock.

Context and impact

Prometheus aims to build an 'artificial general engineer' — software that automates the design and manufacturing of complex physical systems (jet engines, drug compounds). It is one of the largest single bets on the 'physical AI' category alongside Physical Intelligence and Figure. The $41B valuation puts it in the top five most-expensive AI startups outside OpenAI/Anthropic/xAI/Cursor.
