Startup's Mini Nuclear Reactor Powers Nvidia's Latest AI Chips

In June 2026, a small nuclear reactor built by Valar Atomics successfully powered Nvidia's newest AI computer system in Utah. The two companies then announced plans for a 30-megawatt AI factory that needs no water to cool. Weeks later, on August 3, 2026, Valar raised $1 billion from investors, valuing the company at $6 billion.
