Jeff Bezos is getting a new job. He’ll step in as co-CEO of Project Prometheus, an AI startup he’s helping fund that wants to use artificial intelligence to rethink how computers, cars, and even spacecraft get built.

The New York Times reports the company has already raised $6.2 billion, putting it near the top of the leaderboard for early-stage AI funding. Bezos will run it with co-founder Vik Bajaj, a physicist and chemist who spent time at Google X before leading Verily inside Alphabet’s portfolio.

Project Prometheus has nearly 100 employees and has hired from OpenAI, DeepMind, and Meta. For Bezos, this is his first actual operating job since leaving Amazon in 2021, though he’s stayed busy cheering on Blue Origin, which just landed its New Glenn booster for the first time.

And yes, the timing is hard to ignore. Elon Musk already runs his own AI startup, xAI, and is folding its tech into Tesla and SpaceX. Bezos has Blue Origin, Musk has SpaceX. Musk owns X, Bezos owns The Washington Post. Musk builds electric cars, Bezos backs Slate Auto.

The two richest rivals in tech keep finding the same arenas to compete in. Now they’re both going after AI-powered manufacturing.
