General Fusion has completed its merger with Spring Valley Acquisition Corp. III, clearing the path to become the first publicly traded pure-play fusion energy company in history. Shares are expected to begin trading on the Nasdaq exchange on Monday, July 13, under the ticker symbol GFUZ.
The 24-year-old company, headquartered in British Columbia, Canada, is striving to harness nuclear fusion — the same reaction that powers the sun — to generate commercially viable, carbon-free electricity. If successful, it would represent one of the greatest technological breakthroughs in history, offering virtually limitless clean energy.
The milestone comes after a challenging year for the company, which implemented layoffs and saw its CEO make a public plea for new investment before announcing the $1 billion SPAC deal in January. In a sign of commercial momentum, General Fusion recently partnered with Italian energy infrastructure company Renexia to begin planning commercial deployment of its technology in Italy.
General Fusion has been at the forefront of fusion energy development for nearly a quarter century. The company was also recently ranked first on TIME's prestigious list of the World's Top GreenTech Companies of 2026.
Fusion energy has long been seen as the holy grail of clean power — producing no carbon emissions, no long-lived radioactive waste, and using fuel derived from seawater. Unlike fission, which splits atoms, fusion combines them, releasing enormous energy. Despite decades of research and billions in investment, no company has yet demonstrated a commercially viable fusion reactor.
General Fusion's approach, known as Magnetized Target Fusion (MTF), compresses magnetically confined plasma using mechanical pistons — a design the company says is simpler and cheaper than competing approaches like tokamaks or stellarators.
The public listing marks a watershed moment for the fusion industry, bringing public market scrutiny and capital to a sector long dominated by government-funded research. It also signals growing investor conviction that fusion energy may finally be approaching commercial reality, even as significant technical hurdles remain.
