General Fusion Group shares rose 23% on Tuesday following the company's debut on the Nasdaq under the ticker symbol GFUZ. The listing follows a business combination with Spring Valley Acquisition Corp III. General Fusion is going public with around $150 million in available cash, comprising proceeds from a private placement and trust funds, to advance its Magnetized Target Fusion (MTF) technology.

The funding is expected to support the company’s Lawson program through key technical milestones targeted for completion by 2028. General Fusion’s MTF technology is designed to address major challenges in fusion commercialization by using existing materials and avoiding the need for superconducting magnets or high-powered lasers. In early 2025, the company began operating its LM26 fusion demonstration machine, which was built in less than two years and represents the first MTF system developed at a commercially relevant scale.

First Publicly Listed Fusion Company

General Fusion is developing MTF technology, combining magnetic confinement with mechanical compression to achieve fusion conditions. The company operates LM26, a large-scale demonstration system designed to validate its technology and support the development of commercial fusion power plants.
