Global Fusion Capital Surpasses Fourteen Billion Dollars
On November 12, 2026, the International Atomic Energy Agency convened the inaugural ministerial session of the World Fusion Energy Group in Vienna, Austria. The United States Mission delivered a formal national policy declaration, confirming that private and public capital investments in nuclear fusion reached 14 billion dollars globally. According to the official United States delegation report, domestic American projects secured nearly 10 billion dollars. The United States Department of Energy released its finalized Fusion Science and Technology Roadmap.
The federal roadmap was formulated through consultations with over 800 scientific contributors across national laboratories and academic faculties. It provides a structured timeline to establish commercially viable fusion power demonstration reactors connecting to civilian utility grids by the mid-2030s. The United States Permanent Mission to International Organizations in Vienna said reported global fusion investments exceeded 14 billion dollars, with nearly 10 billion dollars invested in the United States alone.
Simultaneously in Washington, the Department of Energy granted regulatory operating authorization for advanced non-light-water test reactors under a modernized approval framework. World Nuclear News reported that developers including Kairos Power secured final operational pathway approvals for low-power molten salt experimental facilities. Molten salt coolant architectures operate at atmospheric pressure, eliminating catastrophic high-pressure steam explosion risks inherent in legacy light-water reactors. The experimental reactors will evaluate high-assay low-enriched uranium fuel pebbles under continuous thermal stress.
