Jeff Bezos, founder of Amazon, is making one of the biggest bets in artificial intelligence history with his new AI startup Prometheus, which has secured $12 billion in Series B funding and hit a $41 billion valuation. The groundbreaking funding round was announced on June 11, 2026, when the company officially emerged from stealth mode.
Prometheus is co-founded and co-led by Jeff Bezos and Vikram “Vik” Bajaj, a former Google Life Sciences executive and biotechnology entrepreneur who previously worked at Google. The startup is now officially operating with Bezos serving as co-CEO alongside Bajaj.
The company’s ambitious goal is to build an “artificial general engineer” — an AI system capable of designing and manufacturing complex physical products like jet engines, medical devices, skyscrapers, and spacecraft. Unlike most AI companies focused on chatbots, Prometheus aims to bring AI into the heart of engineering and industrial innovation.
Major investors in the $12 billion round include JPMorgan Chase, Goldman Sachs, BlackRock, DST Global, Arch Venture Partners, and Bezos himself. The funding represents a massive increase from the company’s previous $38 billion valuation achieved in April 2026 with a $10 billion round.
Bezos called the company’s vision to “make the dream-build loop 10 times faster” for industrial engineering projects. This investment marks Bezos as a significant player in the AI boom, focusing on physical product manufacturing rather than software.
