Valar's long-term commercial vision: "America's first nuclear gigasites" — clusters of thousands of HTGRs designed to produce industrial power and carbon-based fuels cheaper than oil. Behind-the-meter deployment at scale. Three primary applications: (1) Synthetic carbon-based fuels (the global liquid fuel market is ~100M barrels/day = vast scale headroom); (2) Hydrogen production via high-temperature electrolysis; (3) Data center power. The 900°C outlet temperature unlocks markets electric-only generation cannot serve.
April 2025 lawsuit filed against the Nuclear Regulatory Commission. Co-plaintiffs: Last Energy, Deep Fission, and the states of Texas, Utah, Louisiana, Florida, and Arizona. Argument: NRC's licensing framework unlawfully restricts small-scale reactor innovation by requiring the same approval process for low-power test reactors as for full-scale commercial plants. Sought outcome: shift regulatory authority for small reactors to individual states. Combative regulatory posture few young companies would adopt.
Valar's flagship reactor — 100 kWt high-temperature gas-cooled reactor. Helium coolant, TRISO HALEU fuel, graphite moderator. Outlet temperatures up to 900°C — TRIPLE that of conventional water reactors. Naming convention from CEO Taylor's great-grandfather Ward Schaap (Manhattan Project physicist). Standardized design for "gigasite" deployment — clusters of thousands of HTGRs co-located behind-the-meter for hydrogen production, synthetic fuels, and data center power. NOVA Core (zero-power criticality assembly) achieved criticality at Los Alamos National Laboratory's National Criticality Experiments Research Center November 2025 — described by Breakthrough Institute as the first DOE Reactor Pilot Program criticality milestone.
Broke ground September 2025 at the state-owned San Rafael Energy Research Center in Orangeville, Utah. Construction partners: Kiewit Corporation (engineering and construction), Goree (architecture and design), Sprung (building structure). **Ward 250 reactor airlifted from California to Utah aboard three C-17 Globemaster military cargo aircraft in February 2026** — joint DoD + DOE operation that doubled as a literal proof-of-concept for rapid reactor deployment. Targeting power operations before July 4, 2026 (Trump May 2025 EO 14301 deadline). Partnership with State of Utah and DOE.
Valar's first international deployment — Ward One is the first uranium-containing commercial reactor planned for the company. Leverages the **123 Agreement** between the United States and the Philippines (US framework for international civilian nuclear cooperation). Pitch frame: "deploy overseas first" to bypass US regulatory burdens. Multi-step plan: pilot test-scale reactor → build two full-scale reactors → first integrated reactor (gigasite-format).
Two parallel infrastructure milestones: (1) Ward Zero — Valar's first reactor prototype assembled February 2025 using silicon carbide instead of uranium in the core (non-nuclear validation). (2) DOE Fuel Line Pilot Program — Valar selected September 2025 as one of four companies. The Fuel Line Pilot Program leverages DOE authorization to build and operate nuclear fuel production lines for research, development, and demonstration — establishes domestic nuclear fuel supply chain for testing new reactors.
Pre-seed funding round, approximately $2M, prior to formal Seed round disclosure. Brought cumulative pre-Seed-disclosure funding to $21M as of February 2025.
Seed funding round announced February 20, 2025 concurrent with Valar's emergence from stealth. Funds first test reactor development. Brought total funding to ~$21M including pre-seed.
$130M Series A funding round announced November 13, 2025. Brought total fundraising to $150M (combining all rounds). Investor lineup notable for defense/tech crossover: Anduril founder Palmer Luckey, Palantir CTO Shyam Sankar, Lockheed Martin board member John Donovan. Same week: Valar achieved NOVA Core zero-power criticality at Los Alamos.
$450M Series B at $2B valuation announced March 2026 — five months after NOVA Core zero-power criticality at Los Alamos. Most aggressive post-criticality re-rating in the dataset. Investor base anchored by Palmer Luckey (Anduril). Brings cumulative funding to ~$600M+. Targets industrial gigasite buildout including Ward 250 power operations + Philippines deployment + Department of Defense partnership scaling.
