General Fusion Lists on Nasdaq as GFUZ, Shares Jump After SPAC Merger
General Fusion began trading on Nasdaq under the ticker GFUZ on July 13, 2026, marking the first publicly listed fusion power company; shares surged in early trading. The listing follows a reverse merger with Spring Valley Acquisition Corp. III and a private financing round, and the company says it holds roughly $150 million in cash.
Nasdaq Debut and Early Trading
General Fusion opened on the Nasdaq on July 13, 2026, and saw immediate buying interest that lifted the stock sharply from its reference price. By mid-afternoon trading the shares were up roughly 40% from an initial quote of $12.85, reflecting strong market appetite for a listed entrant in the fusion sector.
The debut establishes General Fusion as the first fusion power company to trade publicly in the United States, preceding other private rivals that have signaled plans to pursue public listings. The listing is being watched by investors and industry observers as a bellwether for investor appetite in capital-intensive clean-energy technologies.
Deal Completion and Cash Position
The company completed its reverse merger with Spring Valley Acquisition Corp. III in the days before the Nasdaq listing, a transaction first announced in January 2026. Alongside the de-SPAC, General Fusion secured $108 million from private investors and reported a combined cash position of roughly $150 million.
That reported cash figure is the company’s working baseline as it transitions to public reporting and investor scrutiny. Management has framed the combined proceeds as providing runway for near-term development work and to advance its reactor testing program.
Redemptions Reduced SPAC Proceeds
Like many de-SPAC transactions, the merger saw investor redemptions that substantially trimmed the amount of cash rolled into the business trust. While the company has not released a precise redemption total, press reports have estimated that proceeds from the SPAC may have been reduced to less than $30 million after redemptions and fees.
The dynamics underline a common challenge for companies using SPACs to access public capital: initial headline cash totals can be eroded by redemptions, changing the financing calculus once the deal closes. General Fusion’s supplementary private raise partially offset that shortfall but leaves the company with a smaller than-anticipated immediate war chest.
Technology Approach and LM26 Program
General Fusion’s technical pathway centers on magnetized target fusion, a method that forms a magnetized plasma target and compresses it inside a chamber surrounded by a liquid-metal blanket. The company’s design relies on mechanically driven drivers that compress a liquid lithium liner around the plasma to achieve the temperatures and pressures required for fusion reactions.
The firm has been developing a test device known as LM26 as a critical step toward demonstrating net energy gain, or “breakeven.” Funding interruptions have pushed previously optimistic timelines back; company statements now project that breakeven objectives are unlikely this year and may shift into 2028 or later, with a first commercial plant targeted for approximately 2035.
Operational Strains and Workforce Reductions
General Fusion entered the public transaction after a period of financial strain that included failed fundraising efforts and workforce cuts. In May 2025 the company reduced headcount by about a quarter as it sought to conserve cash, and a subsequent August 2025 capital infusion of around $22 million was described by insiders as a conditional “pay-to-play” bridge round.
Those measures bought the company additional runway but did not eliminate the need for larger capital commitments to advance full-scale reactor development. The decision to pursue a reverse merger and an accompanying private placement reflects a broader shift toward securing public-market access to support long-term engineering milestones.
Sector Standing and Competitive Landscape
Founded in 2002, General Fusion is one of the longest-running private fusion ventures and has raised more than $600 million from private backers over its history. Its Nasdaq listing places at least one fusion developer on a public market for the first time and will provide a new price-discovery mechanism for investors assessing the viability of nuclear-fusion startups.
Competitors pursuing alternative fusion approaches remain privately held and continue to attract venture and strategic capital, with some planning or signaling future public transactions. The success or struggle of General Fusion as a public company will likely influence investor sentiment toward other fusion developers and the sector’s broader fundraising environment.
Public scrutiny will intensify in the weeks ahead as General Fusion begins filing quarterly reports and discloses more detail on its cash position and development milestones. Investors will be watching how the company allocates its reported $150 million and how quickly it can resume testing toward breakeven and larger-scale demonstrations.
General Fusion faces a long technical and regulatory path from prototype testing to commercial power plants, and its Nasdaq debut gives both capital access and a new set of expectations from shareholders and markets.
