Project Prometheus Raises Roughly $10B at $38B Valuation to Build Physical AI Systems

Project Prometheus just pulled in roughly $10B at a $38B valuation… and did it without a product on the shelf. That’s not hype, that’s conviction with a capital stack. Jeff Bezos and Vikram Bajaj are not chasing chatbots that write poetry. They’re building machines that understand gravity, friction, heat, pressure… the stuff that actually breaks when you’re trying to manufacture something real. Call it physical AI if you want, but it feels more like teaching silicon to respect physics instead of just autocomplete it. Respect to Jeff Bezos and Vikram Bajaj for stepping back into the arena and swinging at something this heavy.

No single lead investor here, which tells you everything. JPMorgan Chase, BlackRock, DST Global, ARCH Venture Partners… this isn’t a round, it’s a table of institutions deciding they don’t want to be late to whatever this becomes. And Bob Nelsen doesn’t hang around small ideas. Rick Klausner doesn’t either. When that mix shows up, it’s usually because the problem is big enough to deserve it.

The company came out of stealth in November 2025 with $6.2B, already sounding like a final round for most startups. Now they’ve stacked it to north of $16B total, hiring talent out of places like OpenAI and DeepMind, while setting up shop across San Francisco, London, and Zurich. No revenue. No product launch. Just a thesis: if AI is going to matter, it has to leave the screen and survive contact with the real world.

And that’s the quiet lesson here. Capital doesn’t chase noise at this level. It chases inevitability. Prometheus isn’t selling features, it’s selling belief that whoever cracks “AI that works in reality” owns the next industrial cycle. Not the next app cycle. The one that moves atoms, not just pixels.

There’s also a strategic patience baked into this. Acquiring General Agents, bringing in agentic systems, stacking infrastructure talent like Kyle Kosic… this isn’t a sprint to demo day. It’s a long game where data isn’t scraped, it’s generated through interaction with the physical world. Harder to build, harder to fake, and a lot harder to compete with once it works.
