General Fusion Rings Nasdaq Bell as First Publicly Traded Fusion Company

This milestone marks a new chapter for the Vancouver-based fusion developer, which has been pursuing commercial fusion power for more than two decades . But the road to the bell-ringing was anything but straightforward.

The SPAC Merger: A $1 Billion Deal with Heavy Redemptions

General Fusion went public through a merger with Spring Valley Acquisition Corp. III (NASDAQ: SVAC), a special purpose acquisition company (SPAC) focused on energy and decarbonization .

The high redemption rate — roughly 87% of SPAC unitholders cashed out — meant General Fusion had to rely primarily on the PIPE and its own cash to fund operations . Axios reported that the SPAC proceeds are expected to keep the company funded through at least 2028 .

Technology: Magnetized Target Fusion (MTF)

General Fusion uses Magnetized Target Fusion (MTF), a hybrid approach that magnetically confines a warm plasma and then mechanically compresses it to fusion conditions . This is distinct from the tokamak or stellarator designs pursued by other fusion companies. The company holds 210 patents issued and pending, and is one of only four private companies worldwide to have achieved and published meaningful peer-reviewed fusion results .

LM26: The Demonstration Machine

Lawson Machine 26 (LM26) — General Fusion's large-scale MTF demonstration machine in Richmond, B.C. — was built and commissioned in under two years . In June 2026, the company announced it had achieved compressional plasma heating on LM26, reporting plasma electron temperatures of about 0.72 keV (roughly 8.4 million °C) . The machine is designed to ultimately reach 10 keV (~100 million °C) and scientific breakeven equivalent .

LM26 compresses plasma with a lithium liner at 50% of commercial-scale diameter, and is now operating and forming plasmas regularly .

Roadmap to Commercial Fusion

The company's stated goal is to deliver commercial fusion energy to the grid by the early to mid-2030s .

Current Status and Key Caveats

General Fusion is now a Nasdaq-listed public company (GFUZ) with approximately US$150 million in cash to fund the LM26 program through critical milestones . The stock debuted strong, gaining roughly 40% on its first day, though the SPAC structure carried high redemptions and the company faces the typical risks of pre-revenue fusion development . The company is actively pursuing international commercialization, including a recently announced partnership to explore deploying MTF technology in Italy .

A necessary caution: Fusion energy remains an unproven technology at commercial scale. General Fusion's timeline, like all fusion developers, depends on successfully achieving scientific breakeven and then engineering a grid-ready plant — both high-risk milestones that no private company has yet accomplished. The company also faced layoffs and a public plea for investment by its CEO in 2025 before securing the SPAC deal .
