ConvictionDDream VenturesHHOF CapitalRiot VenturesValar Atomics is building high-temperature gas reactors meant to run in large numbers on single sites it calls gigasites, selling grid-independent power for hydrogen production, data centers, heavy industry, and clean hydrocarbon fuel synthesis. Its Ward 250 test reactor reached full-power fueled criticality at Utah's San Rafael Energy Lab in June 2026, the first DOE-authorized advanced reactor built outside the national laboratory system.
Isaiah P. Taylor founded the company in 2023. Four executive orders gave Valar a mandate to test its reactor, and it partnered with the Department of Energy and the State of Utah to reach that milestone ahead of America's 250th birthday.
