General Fusion began trading on the Nasdaq on Monday 13 July 2026 under the ticker GFUZ, becoming the first fusion energy company listed on a major exchange, and the stock rose about 40 percent from its 12.85 dollar open by midday.1 TechCrunch 2026-07-13 GFUZ began trading Monday 13 July 2026, opened at 12.85 dollars and rose about 40 percent by midday; redemptions cut the SPAC trust from an expected 230 million to roughly 30 million dollars after fees, alongside a 108 million dollar private placement; over 600 million dollars raised privately since 2002; failed 125 million dollar raise, 25 percent layoffs in May 2025, 22 million dollar pay to play round; breakeven slipped from 2026 to 2028 or later, commercial plant around 2035. Open source The listing arrived in the same month as the Fusion Industry Association's annual report, which counted a record 4.48 billion dollars raised by 56 private fusion companies in the 12 months to July 2026, up 69 percent on the prior year.3 Fusion Industry Association 2026-07-21 Record 4.48 billion dollars raised by 56 companies in the 12 months to July 2026, up 69 percent, total 14.24 billion since 2021; average 2.7 billion dollars needed per company, up to 10.9 billion; rounds by CFS 863m, Proxima 518m, Helion 465m, Inertia 450m; 16,000 plus employed; 71 percent expect a first commercial plant in the 2030s. Open source The company enters public markets with roughly 150 million dollars in cash against a sector where the average company says it needs 2.7 billion dollars to reach commercialization.2 General Fusion 2026-07-13 Trading in GFUZ began on Nasdaq 13 July 2026 with approximately 150 million US dollars in cash to fund the Lawson program through milestones targeted for 2028; LM26 at 50 percent commercial scale diameter has heated plasma to about 0.72 keV; CEO Greg Twinney quoted. Open source 3 Fusion Industry Association 2026-07-21 Record 4.48 billion dollars raised by 56 companies in the 12 months to July 2026, up 69 percent, total 14.24 billion since 2021; average 2.7 billion dollars needed per company, up to 10.9 billion; rounds by CFS 863m, Proxima 518m, Helion 465m, Inertia 450m; 16,000 plus employed; 71 percent expect a first commercial plant in the 2030s. Open source We assess with high confidence that this listing is a financing adaptation rather than a technology milestone: fusion's capital appetite has outgrown what private rounds comfortably supply, and the AI data center power story is what makes public investors willing to hold a pre revenue science company. With moderate confidence, GFUZ's value over the next two years will track its 2028 Lawson milestones, not its revenue, because it has none to track.

How the first fusion ticker actually got here

The route to the bell was not triumphant. General Fusion, founded in 2002 and backed by more than 600 million dollars of private money over its life, failed to close a 125 million dollar raise in early 2025, laid off a quarter of its staff in May 2025, and survived on a 22 million dollar pay to play round that August.1 TechCrunch 2026-07-13 GFUZ began trading Monday 13 July 2026, opened at 12.85 dollars and rose about 40 percent by midday; redemptions cut the SPAC trust from an expected 230 million to roughly 30 million dollars after fees, alongside a 108 million dollar private placement; over 600 million dollars raised privately since 2002; failed 125 million dollar raise, 25 percent layoffs in May 2025, 22 million dollar pay to play round; breakeven slipped from 2026 to 2028 or later, commercial plant around 2035. Open source The SPAC merger with Spring Valley Acquisition Corp. III, announced in January 2026, was itself diluted by reality: heavy redemptions cut an expected 230 million dollars of trust capital to roughly 30 million dollars after fees, leaving a 108 million dollar private placement to do most of the work.1 TechCrunch 2026-07-13 GFUZ began trading Monday 13 July 2026, opened at 12.85 dollars and rose about 40 percent by midday; redemptions cut the SPAC trust from an expected 230 million to roughly 30 million dollars after fees, alongside a 108 million dollar private placement; over 600 million dollars raised privately since 2002; failed 125 million dollar raise, 25 percent layoffs in May 2025, 22 million dollar pay to play round; breakeven slipped from 2026 to 2028 or later, commercial plant around 2035. Open source The company's own announcement puts the resulting cash position at approximately 150 million US dollars, earmarked to carry its Lawson program through technical milestones targeted for 2028.2 General Fusion 2026-07-13 Trading in GFUZ began on Nasdaq 13 July 2026 with approximately 150 million US dollars in cash to fund the Lawson program through milestones targeted for 2028; LM26 at 50 percent commercial scale diameter has heated plasma to about 0.72 keV; CEO Greg Twinney quoted. Open source

What that money buys is specific and measurable. The LM26 machine in Vancouver, at 50 percent of commercial scale diameter, has heated plasma to about 0.72 keV, roughly 8.4 million degrees Celsius.2 General Fusion 2026-07-13 Trading in GFUZ began on Nasdaq 13 July 2026 with approximately 150 million US dollars in cash to fund the Lawson program through milestones targeted for 2028; LM26 at 50 percent commercial scale diameter has heated plasma to about 0.72 keV; CEO Greg Twinney quoted. Open source The stated 2028 targets are 1 keV, then 10 keV, then a demonstration of the Lawson criterion, the threshold for net fusion energy, on a machine that compresses plasma with a liquid lithium liner rather than superconducting magnets or lasers.4 StockTitan 2026-07-13 2028 milestones of 1 keV and 10 keV plasma heating and a Lawson criterion demonstration on LM26; over 200,000 plasma experiments across two decades; lithium liner compression without superconducting magnets or lasers; framework agreement with Renexia for potential deployment in Italy.

Open source Note the sourcing caveat: the cash figure, the temperature record and the milestone schedule are the company's own statements, made at the moment it was selling shares, and the breakeven target has already slipped once, from 2026 to 2028 or later.1 TechCrunch 2026-07-13 GFUZ began trading Monday 13 July 2026, opened at 12.85 dollars and rose about 40 percent by midday; redemptions cut the SPAC trust from an expected 230 million to roughly 30 million dollars after fees, alongside a 108 million dollar private placement; over 600 million dollars raised privately since 2002; failed 125 million dollar raise, 25 percent layoffs in May 2025, 22 million dollar pay to play round; breakeven slipped from 2026 to 2028 or later, commercial plant around 2035.

The report that explains the timing

The FIA's 2026 survey is the context that makes a fusion SPAC rational. Private fusion companies raised 4.48 billion dollars in the year to July 2026, the sector's best year since tracking began, bringing cumulative investment since 2021 to 14.24 billion dollars across a company count that has grown from 23 to 56.3 Fusion Industry Association 2026-07-21 Record 4.48 billion dollars raised by 56 companies in the 12 months to July 2026, up 69 percent, total 14.24 billion since 2021; average 2.7 billion dollars needed per company, up to 10.9 billion; rounds by CFS 863m, Proxima 518m, Helion 465m, Inertia 450m; 16,000 plus employed; 71 percent expect a first commercial plant in the 2030s. Open source The rounds behind that number are getting bigger: Commonwealth Fusion Systems at 863 million dollars, Proxima Fusion at 518 million, Helion at 465 million, Inertia at 450 million.3 Fusion Industry Association 2026-07-21 Record 4.48 billion dollars raised by 56 companies in the 12 months to July 2026, up 69 percent, total 14.24 billion since 2021; average 2.7 billion dollars needed per company, up to 10.9 billion; rounds by CFS 863m, Proxima 518m, Helion 465m, Inertia 450m; 16,000 plus employed; 71 percent expect a first commercial plant in the 2030s. Open source Yet the same survey has companies estimating an average of 2.7 billion dollars each to reach commercialization, with individual estimates running as high as 10.9 billion.3 Fusion Industry Association 2026-07-21 Record 4.48 billion dollars raised by 56 companies in the 12 months to July 2026, up 69 percent, total 14.24 billion since 2021; average 2.7 billion dollars needed per company, up to 10.9 billion; rounds by CFS 863m, Proxima 518m, Helion 465m, Inertia 450m; 16,000 plus employed; 71 percent expect a first commercial plant in the 2030s. Open source The arithmetic is the story: even a record year spread across 56 companies does not close that gap, so the sector needs new pools of capital, and public equity is the largest one there is.

The demand side of the pitch is explicitly AI. FIA chief executive Andrew Holland tied the record year to the need for large amounts of clean energy to power AI, and the report notes that AI energy needs are producing power purchase agreements years ahead of any electrons: Microsoft signed with Helion in 2023, Google with Commonwealth Fusion Systems in 2025.5 Tomorrow's World Today 2026-07-21 FIA CEO Andrew Holland tied the record year to the need for large amounts of clean energy for AI; AI energy needs driving power purchase agreements, Microsoft with Helion in 2023 and Google with Commonwealth Fusion Systems in 2025; TAE Technologies and General Fusion both preparing 2026 Nasdaq listings. Open source We assess with moderate confidence that hyperscaler demand is now the load bearing narrative for fusion finance: it converts a physics program into an answer to a named, quantified problem, data center power, that public investors already price into utilities and grid stocks. That narrative pulled General Fusion through the door first, with TAE Technologies preparing to follow onto Nasdaq this year.5 Tomorrow's World Today 2026-07-21 FIA CEO Andrew Holland tied the record year to the need for large amounts of clean energy for AI; AI energy needs driving power purchase agreements, Microsoft with Helion in 2023 and Google with Commonwealth Fusion Systems in 2025; TAE Technologies and General Fusion both preparing 2026 Nasdaq listings.

Who gains and who loses

The clearest winners are the next fusion companies in the queue. TAE now has a public comparable and a demonstrated 40 percent day one pop to show its own bankers.1 TechCrunch 2026-07-13 GFUZ began trading Monday 13 July 2026, opened at 12.85 dollars and rose about 40 percent by midday; redemptions cut the SPAC trust from an expected 230 million to roughly 30 million dollars after fees, alongside a 108 million dollar private placement; over 600 million dollars raised privately since 2002; failed 125 million dollar raise, 25 percent layoffs in May 2025, 22 million dollar pay to play round; breakeven slipped from 2026 to 2028 or later, commercial plant around 2035.

Open source General Fusion itself gains a permanent financing channel: a listed company can sell shares at each milestone instead of renegotiating survival with private holders, which is exactly what its 2025 near death experience showed it needed.1 TechCrunch 2026-07-13 GFUZ began trading Monday 13 July 2026, opened at 12.85 dollars and rose about 40 percent by midday; redemptions cut the SPAC trust from an expected 230 million to roughly 30 million dollars after fees, alongside a 108 million dollar private placement; over 600 million dollars raised privately since 2002; failed 125 million dollar raise, 25 percent layoffs in May 2025, 22 million dollar pay to play round; breakeven slipped from 2026 to 2028 or later, commercial plant around 2035. Open source Retail and generalist institutional investors gain their first direct fusion exposure on a major exchange, for better or worse.

The losers are subtler. Private fusion companies that stay private now have a public mark against which their own valuations will be tested, and a listed peer that reprices on every plasma shot. General Fusion's employees and long term holders absorb a new cost: quarterly disclosure discipline applied to a science program whose natural cadence is years, where a delayed milestone becomes a sell signal rather than a footnote. And the sector as a whole takes on reputational leverage: the first ticker is now the proxy, so a GFUZ collapse would be read as a fusion verdict, however unfairly, by capital that cannot distinguish magnetized target fusion from a tokamak.

The counter-case

The strongest argument against reading this as fusion's arrival on public markets is the float. With redemptions shrinking the trust to about 30 million dollars, the 40 percent first day move happened on a thin share supply, which makes the price a poor signal of institutional conviction.1 TechCrunch 2026-07-13 GFUZ began trading Monday 13 July 2026, opened at 12.85 dollars and rose about 40 percent by midday; redemptions cut the SPAC trust from an expected 230 million to roughly 30 million dollars after fees, alongside a 108 million dollar private placement; over 600 million dollars raised privately since 2002; failed 125 million dollar raise, 25 percent layoffs in May 2025, 22 million dollar pay to play round; breakeven slipped from 2026 to 2028 or later, commercial plant around 2035. Open source A company that could not close a 125 million dollar private round in early 2025 raising roughly 150 million dollars via SPAC in 2026 may say more about SPAC mechanics than about a repriced fusion sector.1 TechCrunch 2026-07-13 GFUZ began trading Monday 13 July 2026, opened at 12.85 dollars and rose about 40 percent by midday; redemptions cut the SPAC trust from an expected 230 million to roughly 30 million dollars after fees, alongside a 108 million dollar private placement; over 600 million dollars raised privately since 2002; failed 125 million dollar raise, 25 percent layoffs in May 2025, 22 million dollar pay to play round; breakeven slipped from 2026 to 2028 or later, commercial plant around 2035. Open source The technical thesis has the same fragility: breakeven has already moved from 2026 to 2028 or later, commercial power is pencilled around 2035, and 150 million dollars is under 6 percent of the sector's own average estimate of the capital required to get there.1 TechCrunch 2026-07-13 GFUZ began trading Monday 13 July 2026, opened at 12.85 dollars and rose about 40 percent by midday; redemptions cut the SPAC trust from an expected 230 million to roughly 30 million dollars after fees, alongside a 108 million dollar private placement; over 600 million dollars raised privately since 2002; failed 125 million dollar raise, 25 percent layoffs in May 2025, 22 million dollar pay to play round; breakeven slipped from 2026 to 2028 or later, commercial plant around 2035.

Open source For the main assessment to fail, GFUZ would need to trade down to a level that forecloses follow on raises before the 2028 milestones, in which case the listing bought visibility, not runway, and the public market experiment ends where the private one nearly did.

What to watch

  • LM26 hits 1 keV. The first of the stated milestones on the road to the Lawson demonstration; reaching it during 2027 keeps the 2028 schedule credible, while silence through 2027 would mark a second slip on a program that already moved once.4 StockTitan 2026-07-13 2028 milestones of 1 keV and 10 keV plasma heating and a Lawson criterion demonstration on LM26; over 200,000 plasma experiments across two decades; lithium liner compression without superconducting magnets or lasers; framework agreement with Renexia for potential deployment in Italy. Open source
  • TAE completes its Nasdaq listing in 2026. A second fusion ticker this year confirms a repeatable financing channel; a shelved TAE deal would suggest GFUZ was a one off window.5 Tomorrow's World Today 2026-07-21 FIA CEO Andrew Holland tied the record year to the need for large amounts of clean energy for AI; AI energy needs driving power purchase agreements, Microsoft with Helion in 2023 and Google with Commonwealth Fusion Systems in 2025; TAE Technologies and General Fusion both preparing 2026 Nasdaq listings. Open source
  • A GFUZ follow on raise within 12 months. The size and price of the first secondary offering, by mid 2027, is the real test of whether public markets will fund the gap between 150 million dollars in hand and the billions the sector says commercialization costs.2 General Fusion 2026-07-13 Trading in GFUZ began on Nasdaq 13 July 2026 with approximately 150 million US dollars in cash to fund the Lawson program through milestones targeted for 2028; LM26 at 50 percent commercial scale diameter has heated plasma to about 0.72 keV; CEO Greg Twinney quoted.

Open source
  • Another hyperscaler power purchase agreement. A third named AI or cloud buyer signing a fusion PPA by mid 2027, following Microsoft and Google, would harden the demand story from narrative into a pattern.5 Tomorrow's World Today 2026-07-21 FIA CEO Andrew Holland tied the record year to the need for large amounts of clean energy for AI; AI energy needs driving power purchase agreements, Microsoft with Helion in 2023 and Google with Commonwealth Fusion Systems in 2025; TAE Technologies and General Fusion both preparing 2026 Nasdaq listings.

  • Next year's FIA number. If the 2027 report shows annual funding holding above 4.48 billion dollars with public proceeds now inside the total, fusion finance has genuinely changed shape; a reversion toward the pre 2026 pace would date this year as a peak.3 Fusion Industry Association 2026-07-21 Record 4.48 billion dollars raised by 56 companies in the 12 months to July 2026, up 69 percent, total 14.24 billion since 2021; average 2.7 billion dollars needed per company, up to 10.9 billion; rounds by CFS 863m, Proxima 518m, Helion 465m, Inertia 450m; 16,000 plus employed; 71 percent expect a first commercial plant in the 2030s. Open source

The bell on 13 July did not make fusion power closer. It changed who gets to pay for the wait, and the 2028 milestones will now be graded in public, every trading day.
