Jeff Bezos’ AI startup Prometheus raises $12 billion at a $41 billion valuation

Jeff Bezos’ AI startup Prometheus has reportedly closed a $12 billion funding round at a $41 billion valuation.

The company launched only last November and has not yet shared product details. That makes the raise a striking example of how frontier AI capital is being allocated around teams, compute ambitions, and strategic positioning before public traction.

The deal also reinforces how AI startup financing has split from normal venture scale, with a few companies raising infrastructure-sized rounds almost immediately.
