TerraPower
A Bill Gates-founded advanced nuclear company developing the Natrium sodium-cooled fast reactor with integrated molten-salt energy storage. TerraPower closed a $650 million fundraise backed by NVIDIA, and signed an agreement with Meta in January 2026 to develop up to 8 Natrium reactor and energy storage plants -- Meta's largest advanced-nuclear commitment to date -- providing up to 2.1 gigawatts of power by 2035, on top of a separate deal for Meta's Prometheus AI data center in Ohio alongside Oklo and Vistra.
