General Fusion has successfully demonstrated core capabilities of its LM26 fusion machine, marking a major technical achievement.
Despite raising over $340M to date, the company is now seeking an additional $125M due to global economic and geopolitical pressures.
Workforce reduction and operational downsizing have been implemented to preserve resources as the company courts strategic investors.
General Fusion, a Canadian fusion energy pioneer backed by Jeff Bezos, is urgently seeking $125 million in fresh funding to complete its LM26 demonstration machine—one of the most advanced private fusion systems globally.
Despite raising over $340 million through a combination of government grants and private capital, the 23-year-old company is contending with a sharp shift in the funding landscape. A global economic slowdown and heightened geopolitical tensions have left traditional investors cautious, forcing General Fusion to reduce operations and lay off approximately 25% of its staff.
“Today, we stand as a world leader on the cusp of our most exciting technical milestone yet—and one of the most challenging financial moments in our history,” wrote CEO Greg Twinney in an open letter. “All we need now is the capital to finish the job.”
The Vancouver-based firm made headlines on April 29th after compressing a large-scale magnetized plasma using its LM26 fusion demonstration machine—a “world-first,” according to Twinney. The device, which uses Magnetized Target Fusion (MTF) technology, safely operated with fully integrated diagnostics and successfully trapped a magnetic field with a lithium liner.
“From a technology perspective, we’re one step closer to bringing zero-carbon fusion energy to the electricity grid,” Twinney added. “The science, the machine, and the team are in place. What we need now are the right financing partners.”
LM26, housed in Richmond, B.C., is half the size of General Fusion’s intended commercial device but was designed to produce scalable results. Despite the technical success, the company is now operating the system at reduced capacity to conserve resources.

General Fusion, one of the longest-running private ventures in the field, has also adapted its technology roadmap several times in response to shifting investor expectations and missed performance milestones. It paused the UK-based demonstration project in 2023 to focus entirely on the LM26.
Fusion as an energy source surged into the spotlight in 2022 when U.S. scientists achieved a net energy gain from a fusion reaction. Still, widespread commercialization remains elusive. General Fusion remains one of only four private companies globally to have published peer-reviewed results on the path to breakeven in Nuclear Fusion journals in 2024 and 2025.
The company also recently appointed Bob Smith, former CEO of Blue Origin, as a strategic adviser, signaling an intensified effort to align with experienced leadership and attract fresh capital.
“Today’s funding landscape is more challenging than ever as investors and governments navigate a rapidly shifting and uncertain political and market climate,” said Twinney.
General Fusion is actively exploring strategic partnerships with private investors, government stakeholders, and potential buyers. The CEO emphasized that while the current climate is tough, it presents a unique opportunity for visionary capital to transform the global energy future.
“We’re not a shiny new start-up with a drawing and a dream; we are experienced fusioneers,” Twinney wrote. “This is the time to invest in the company that’s already building the future.”
