The company also recorded significant heating of ions, another important part of the fusion process.
LM26 Reaches Key Fusion Milestone
The achievement is the first of three technical milestones planned for LM26. The next goal is to heat the plasma to 10 keV, with upgrades to the machine already underway.
The final goal is to reach the Lawson criterion, the point at which a fusion reaction can produce more energy than it takes to create it.
How General Fusion's Technology Works
General Fusion said LM26 is the first fusion machine to reach 1 keV using its relatively slow compression approach.
The company uses Magnetized Target Fusion, which combines magnetic fields with compression to heat plasma over milliseconds. Other plasma compression technologies can operate over microseconds or even nanoseconds.
For a future commercial plant, the company plans to use a liquid-metal wall that could protect the machine from neutrons, help produce fuel and capture heat. That heat could then be used to generate steam and produce electricity through a turbine.
The company aims to have its first commercial fusion plant operating around 2035.
First Publicly Listed Fusion Company
In July 2026, General Fusion went public with around $150 million in available cash. This includes 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. It was built in less than two years and represents the first MTF system developed at a commercially relevant scale.
GFUZ Price Action: General Fusion Group shares were up 12.96% at $8.58 at the time of publication on Thursday, according to Benzinga Pro data.
