Valar Atomics

Valar Atomics is developing mass-produced small modular reactors aimed at making nuclear power the cheapest and most reliable energy source worldwide. Unlike traditional nuclear companies that supply electricity to the grid, Valar’s reactors produce grid-independent outputs like hydrogen, synthetic fuels, data center power, and industrial heat. Their main concept, the "Gigasite," is a large industrial campus with hundreds of standardized reactors, enabling Valar to handle design and operation all in one place. They use high-temperature gas reactor (HTGR) technology with TRISO fuel, which the company says offers unmatched safety and resistance to proliferation.

Valar’s key insight is that electricity hasn’t been a great commercial product for nuclear power because it’s hard to store or transport and competes with a grid built around fossil fuels. Instead, Valar focuses on the global liquid fuels market, aiming to produce carbon-neutral synthetic fuels like jet fuel, diesel, and gasoline at prices that can compete with traditional oil refining. Their sulfur-iodine cycle uses nuclear heat to split water into hydrogen and oxygen, then combines the hydrogen with captured CO2 to create hydrocarbons. Besides fuels, Valar sees its reactors as a scalable way to meet the growing power needs of AI data centers, which they estimate will need over 200 terawatt hours of extra grid power by 2030.

Valar Atomics was founded in July 2023, but in just over two years, the company went from idea to hardware faster than most in the nuclear field. In November 2025, Valar reached cold criticality at Los Alamos National Laboratory, becoming the first venture-backed company to sustain a fission reaction. A few weeks later, in February 2026, the U.S. Department of Defense carried out Operation Windlord, airlifting Valar’s Ward250 reactor modules by C-17 military aircraft from California to Hill Air Force Base in Utah. It was the first military airlift of a nuclear reactor ever. Now, Valar is working with Utah’s San Rafael Energy Research Center and the Department of Energy on a pilot program to have reactors operational by July 4, 2026.

Backing this progress is a quickly growing fund. In November 2025, Valar raised $130 million in a funding round led by Snowpoint Ventures, Day One Ventures, and Dream Ventures. Overall, the company raised funds of over $150 million. The last funding round also drew well-known supporters from defense and tech. Figureheads from Anduril Industries, Palantir, and Lockheed Martin as Valar Atomics board members.
