Thea Energy has raised a $100 million Series B, with strong investor demand. This investment means the company is now among the better-funded fusion startups, allowing an improved chance at achieving a commercial reactor.
This funding will support Thea in expanding manufacturing for its smaller magnets and begin construction of its “power plant relevant” demonstration device, Eos. Following Thea’s previous $20 million Series A in 2024, it brings total private investment to $130 million.
Thea hopes to complete its Eos demonstration reactor in 2030 with their commercial version, Helios, coming online in 2034.

Scientists at Ames National Laboratory have developed a new AI tool. It combines advanced AI with physics-based modelling, allowing researchers to predict materials with the appropriate properties to function within fusion reactors.
This tool can benefit scientists in exploring a wide range of potential alloy compositions that can maintain high-temperature strength, while retaining the ductility needed for manufacturing the materials.

Zap Energy recently announced plans to become the first company to simultaneously pursue fusion and fission. Fusion innovators have typically ruled out a connection between their nuclear solution and conventional fission, given public concerns.
Zap’s leaders say that distinction creates a ‘false wall’ that the company is ready to knock down. Building fission technology is not only more predictable and would provide more instant revenue, it also supports research that advances its fusion work.
