Thea Energy's $100M Bet on Mass-Manufactured Fusion Magnets

Fusion startup Thea Energy closed a $100 million Series B on May 27, 2026, to build a demonstration plant using arrays of mass-manufacturable magnets and dynamic software controls—departing from the superconducting magnet path that has historically driven fusion economics. The approach targets cost reduction through existing manufacturing infrastructure rather than novel materials breakthroughs.
