Valar Atomics

Nuclear startup building high-temperature gas-cooled microreactors with TRISO fuel for grid-independent power and hydrogen.
Valar Atomics is a Hawthorne, California-based nuclear startup developing high-temperature gas-cooled microreactors using TRISO fuel, targeting grid-independent power for data centers, industrial heat, and hydrogen production via mass-produced reactor campuses ('gigasites'). Founded in 2023 by Isaiah Taylor. On July 1, 2026 its Ward 250 reactor powered an Nvidia DGX Spark AI computer -- the first time a US nuclear reactor supplied power to an AI chip. In August 2026 Valar closed a $1B Series B led by Sequoia Capital (Shaun Maguire joining the board) at a $6B valuation -- roughly tripling the $2B valuation from its ~$450M April 2026 round -- with Atreides Management, Point72, and Snowpoint Ventures participating, plus a $200M credit facility, to move from proving its reactor works to producing fleets of small reactors for AI data centers.
