General Fusion Becomes First Pure-Play Fusion Company to Go Public via SPAC Deal
On July 13, 2026, Richmond, British Columbia‑based General Fusion Inc. completed a business combination with Spring Valley Acquisition Corp. III, a special‑purpose acquisition company that had recently redomiciled to Canada. The merger, which followed a shareholder vote a few days earlier, launched General Fusion on Nasdaq under the ticker GFUZ and delivered the company roughly US$150 million in cash while valuing the combined entity at more than US$380 million.
At market open, GFUZ shares opened at US$12.80, a 38 % surge from the SPAC’s closing price the day before. General Fusion said the proceeds will fund its Lawson program and key magnetized target fusion (MTF) milestones slated for 2028.
The firm has pursued a unique fusion approach that injects a magnetized plasma target into a cylinder of spinning liquid metal, then compresses the target with steam‑driven pistons to reach fusion‑relevant temperatures and pressures. Founded in 2002, General Fusion has raised about US$400 million to date, remains pre‑revenue, and has yet to demonstrate a net‑energy gain. Last year it announced staff reductions and issued a public plea for additional investment.
General Fusion’s first public listing coincides with Canada’s newly released nuclear energy strategy, which earmarks fusion as a priority technology to help the country maintain its Tier One nuclear status. The strategy calls for investment in research, development, and potential commercial deployment of fusion power.
In addition to the SPAC transaction, the company signed an agreement with Italian energy infrastructure firm Renexia to explore sites for a potential commercial fusion plant in Italy. The partnership aims to deploy General Fusion’s MTF technology in a commercial plant by 2035.
Industry analysts view the public listing as a significant milestone for the nascent fusion sector. Chris Gadomski, lead nuclear analyst at Bloomberg New Energy Finance, told BetaKit that General Fusion’s move to public markets is a “great development” for the company and the broader industry. Gadomski cautioned that the US$150 million in cash is a “drop in the bucket” relative to the capital required to achieve net‑energy gain, noting that many competitors have raised larger sums. He added that while the public‑market debut may not immediately translate into strong returns, it could provide a recurring source of capital for the company’s long‑term development.
General Fusion’s CEO, Greg Twinney, has previously said he joined the company to improve the world for his children and to realize significant financial returns. Twinney’s comments underscore the dual motivation behind the company’s push for commercial fusion.
The SPAC route has been popular for technology companies seeking a faster path to public markets, but academic studies suggest that post‑merger returns are often negative. General Fusion’s listing is the first pure‑play fusion company to take this route, and its performance will be closely watched by investors and regulators.
Other fusion developers are also eyeing public markets. TAE Technologies, a U.S.‑based fusion startup, reportedly plans to go public later in 2026.
The Canadian government’s nuclear strategy, announced in June 2026, aims to build up to ten new nuclear reactors by 2040 and to expand uranium production and the supply chain. The strategy’s emphasis on fusion aligns with General Fusion’s technology, which could provide a low‑carbon, high‑density energy source if commercial viability is achieved.
As of now, General Fusion remains a pre‑commercial entity with a clear roadmap that includes the Lawson Machine 26 demonstrator and a target for commercial deployment in the 2030s. The company’s cash position, while modest compared to the scale of fusion development, provides a buffer for continued research and potential partnership opportunities.
In summary, General Fusion’s Nasdaq debut marks the first time a company focused solely on fusion power has entered public markets. The transaction provides the firm with US$150 million in cash and places it under the scrutiny of public‑market investors, analysts, and regulators. The company’s future progress will be measured against its stated milestones, the Canadian government’s strategic priorities, and the broader fusion industry’s push toward commercial viability.
