Atlas Atomics raises $400M at $2B valuation for nuclear reactor
Summary
Vivek Ramaswamy's nuclear startup, Atlas Atomics, recently raised about $400 million in a Series A funding round, achieving a valuation of approximately $1.9 billion, according to Bloomberg. Atlas Atomics is notable for its heavy water reactor design, which eliminates the need for uranium enrichment, aligning with a growing interest in sustainable nuclear solutions amid robust venture capital investment in the sector. In 2026 alone, investors have committed $4.6 billion to U.S. nuclear startups, driven in part by President Trump's executive order aiming to quadruple the nation's nuclear capacity by 2050. Atlas Atomics aims to introduce its innovative reactor technology in Utah, contributing to a competitive landscape that includes companies like AtkinsRealis, which is also pursuing licensing for similar technology in the U.S.
