Jeff Bezos's AI startup Prometheus raised $12 billion（約1.9兆円） at a $41 billion（約6.6兆円） valuation, betting that artificial intelligence will create a labor shortage by making engineering teams vastly more productive.

What happened

Prometheus, Bezos's industrial AI startup, closed a $12 billion（約1.9兆円） Series B funding round led by JPMorgan Chase, Goldman Sachs, and BlackRock, roughly six months after emerging from stealth with $6.2 billion（約9900億円） in initial funding. The company, which operates with about 150 employees across San Francisco, London, and Zurich, aims to build an "artificial general engineer" capable of designing and manufacturing complex physical products like jet engines.

What to watch

Prometheus is private and cannot be tracked directly by retail investors. If Bezos is correct that AI compresses the design-to-manufacture cycle for jet engines and other capital goods, the industrials sector could become the next AI beneficiary after semiconductors and hyperscalers. If he is wrong, $12 billion（約1.9兆円） of bank-syndicated capital will have been parked in a 150-person startup at a $41 billion（約6.6兆円） valuation.
