Atlas Atomics secured approximately $400 million in a Series A funding round led by General Catalyst. The stealth mode nuclear startup achieved a valuation of $1.9 billion. Venture firms are backing the company as it develops alternative heavy water reactor technology.

This financial backing highlights a wider expansion of private capital flowing into advanced reactor developers. The firm aims to deploy systems that bypass enriched uranium requirements while producing industrial isotopes. Such alternative fuel approaches could reshape supply chains for commercial power generation facilities.

Atlas Atomics, a nuclear startup cofounded and backed by Ohio gubernatorial candidate Vivek Ramaswamy, has raised capital at around a $1.9 billion valuation,

The series A fundraiser generated about $400 million in fresh money, the people said, declining to be identified because the information is private. General Catalyst is leading the round and Andreessen Horowitz is participating in the capital raise.

Atlas Atomics, General Catalyst and Andreessen Horowitz declined to comment.

Still in stealth mode, Atlas is helmed by cofounder Kevin Gan, who spent over 15 years investing in energy companies. He most recently worked at hedge fund Millennium, and prior to that at D.E. Shaw & Co. Balendra Sutharshan, a former chief operating officer of Oak Ridge National Laboratory, is Atlas Atomic's chief nuclear officer.
