Valar Atomics Lands $450 Million at $2B Valuation to Power AI with Small Reactors

Valar Atomics, a nuclear energy startup backed by Palmer Luckey and Palantir CTO Shyam Sankar, led by Isaiah Taylor and the team, has raised fresh capital at a $2 billion valuation, a total of $450 million in the deal, including $340 million in equity and $110 million in debt.

The latest round follows Valar’s $130M raise in November 2025, led by Snowpoint Ventures, with backing from Palmer Luckey, Shyam Sankar, and John Donovan.

Founded in 2023 by Isaiah Taylor, Valar Atomics is building clusters of small, high-temperature gas-cooled reactors (HTGRs) to deliver reliable, carbon-free power for AI data centers, industrial sites, and grid-constrained regions, offering firm baseload without large-scale nuclear builds.

Unlike peers such as TerraPower, Kairos Power, X-energy, and Oklo, Valar focuses on AI data center-scale demand and early alignment with the U.S. Department of Energy’s Nuclear Reactor Pilot Program. It is among the first in the program to reach criticality, the point of a self-sustaining nuclear reaction.

With $450M raised at a $2B valuation, Valar aims to scale small-reactor clusters to meet surging AI-driven power needs, potentially reshaping grid infrastructure and national-security-grade baseload energy.
