General Fusion Stock Jumps 40% on Nasdaq Debut, But Cash Haul Fell Far Short of Projections

General Fusion began trading on the Nasdaq Monday, July 13, 2026, under the ticker GFUZ, making it the first publicly listed fusion power company, according to TechCrunch. Shares jumped as much as 40% from a $12.85 reference price by early afternoon.

The SPAC Deal Got Gutted

General Fusion went public by merging with Spring Valley Acquisition Corp. III, a special purpose acquisition company, in a deal announced in January and completed last week, according to TechCrunch. On paper, that merger could have delivered up to $230 million from Spring Valley's trust account to General Fusion's balance sheet.

It didn't. Most de-SPAC deals see a wave of shareholder redemptions before closing, where SPAC investors cash out their shares instead of rolling into the new public company. General Fusion's deal was no exception. TechCrunch reported that the Globe and Mail estimated General Fusion could end up with less than $30 million from the SPAC trust after redemptions and fees, a fraction of the headline number.

General Fusion has not disclosed the exact redemption figure. That's a gap worth watching. Investors buying GFUZ stock today deserve to know exactly how much of that trust money actually showed up, not just the estimate from a Canadian business paper.

How the Company Got to $150 Million Anyway

General Fusion papered over the redemption shortfall with a $108 million private placement from outside investors, according to both TechCrunch and a GlobeNewswire release from the company. Combine that with whatever came through the SPAC trust, and General Fusion says it's sitting on roughly $150 million in cash.

That $150 million figure is the headline number in the company's own release and in the PRNewswire piece promoting the listing. Both frame it as the fuel for the company's next phase. Neither dwells on the fact that the private placement is doing most of the heavy lifting because the SPAC vehicle underdelivered.

A SPAC merger is supposed to be a faster, cheaper way to go public than a traditional IPO. Instead, General Fusion needed a separate $108 million cash infusion just to make the SPAC deal work at all.

The Company Was Nearly Broke a Year Ago

General Fusion's road to Nasdaq wasn't smooth. TechCrunch reported the company had been trying to raise $125 million back in early 2025 and failed. By May 2025, with that money still not in hand, General Fusion laid off at least 25% of its staff.

Three months after those layoffs, existing investors put in another $22 million in what TechCrunch described as a "pay to play" round, a structure that typically pressures existing shareholders to keep funding the company or risk losing their stake. That bridge round bought time. The SPAC merger, announced in January, was the actual rescue plan.

None of that history appears in General Fusion's own GlobeNewswire release or in the promotional PRNewswire piece, both of which frame Monday's debut purely as a milestone: "more than 200,000 plasma experiments," a No. 1 ranking on TIME's World's Top GreenTech Companies list, and a deployment framework agreement with Renexia S.p.A. in Italy. Those achievements are real and sourced to the company's own materials. But leaving out a near-death funding crisis and a 25% layoff from just over a year ago leaves an incomplete picture for anyone deciding whether to buy the stock.

The Actual Technology Timeline

General Fusion, founded in 2002 and headquartered in Vancouver, uses an approach called magnetized target fusion. Electromagnetic fields create magnetized plasma inside a chamber lined with liquid lithium, and mechanical force compresses the lithium around the fuel until atoms fuse, according to TechCrunch.

The company had hoped to hit "breakeven," the point where a fusion reaction produces more energy than it consumes, sometime in 2026 using its LM26 test device. TechCrunch reported that funding problems pushed that target back to 2028 or later. General Fusion's own materials say it's aiming to have a first power plant running by "approximately 2035."

PRNewswire's coverage cites a recent result from LM26: plasma heated to roughly 8.4 million degrees Celsius, or about 0.72 keV in electron temperature, which the company says is progress toward a 1 keV milestone. That result has been submitted for peer review, according to the PRNewswire piece, but has not yet cleared that review as of this writing.

General Fusion beat Trump-backed rival TAE Technologies to the public markets by several months, according to TechCrunch. Whether that head start matters will depend less on Monday's stock pop and more on whether the $150 million actually gets General Fusion through its 2028 technical milestones, and whether the company needs to go back to investors again before commercial fusion power is anywhere close to real.
