Summary of the Financial Times article (published February 11, 2026):
Title: Fusion funding deals hit record as start-ups move from labs to listings
Key takeaway: Nuclear fusion start-ups completed a record number of funding rounds in 2025, raising the largest total amount since the 2021 peak. This marks a resurgence in investment for the sector.
The article highlights the sector's transition from primarily research/lab-focused development to more commercial and market-oriented stages, including preparations for potential public listings (e.g., IPOs or SPAC-like paths).
While full details are behind a paywall (with only the headline, subtitle, and introductory sentence publicly visible), the piece discusses how increased funding reflects growing investor confidence in fusion energy as a viable clean power source, despite ongoing technical challenges.
This development comes amid broader interest in next-generation energy technologies to address climate goals and energy security. No specific companies, dollar amounts, or individual deal details are accessible without subscription.

Breakthroughs in fusion technology
Nuclear fusion technology has seen significant momentum in recent years, particularly accelerating in 2025 and into early 2026. While commercial fusion power remains years away (with many experts targeting the early-to-mid 2030s for grid-scale deployment), the field has shifted from purely experimental science toward engineering prototypes, massive private investment, and policy support. This builds on foundational breakthroughs like the 2022 ignition at the National Ignition Facility (NIF), with ongoing refinements pushing performance higher.
Key Recent Breakthroughs and Milestones (2025–2026)
Plasma performance records in tokamaks — Test reactors have continued to set benchmarks for sustaining high-temperature plasma:
China's EAST ("artificial sun") surpassed the Greenwald limit (a key plasma density barrier) in early 2026, enabling denser, more stable plasmas critical for higher fusion output.
France's WEST maintained hot plasma for over 1,337 seconds at 50 million °C in February 2025.
South Korea's KSTAR and others have pushed duration and temperature records, feeding data into larger projects like ITER.
Inertial confinement advances — At the U.S. NIF (Lawrence Livermore National Laboratory), experiments in 2025 achieved progressively higher yields:
April 2025: 8.6 MJ yield (target gain of ~4.13) from ~2 MJ laser input — more than doubling prior outputs in some metrics.
Other shots reached 3.5 MJ yields, demonstrating improved burning plasma conditions and applications beyond energy (e.g., nuclear stockpile stewardship).
Private-sector engineering progress — Companies are moving toward integrated demonstrations:
Zap Energy achieved extreme pressures (10,000× sea-level atmospheric) in its Z-pinch device in late 2025.
Pacific Fusion demonstrated rapid, high-current pulses at Sandia’s Z machine in early 2026.
Commonwealth Fusion Systems (CFS) advanced its SPARC tokamak construction (e.g., vacuum vessel and magnet deliveries) and raised $863 million in 2025, targeting net energy soon.
Helion Energy broke ground on its Orion plant (aiming for 50 MW to Microsoft by 2028).
Materials and enabling tech — MIT launched the Laboratory for Materials in Nuclear Technologies (LMNT) in 2025 to address reactor durability. High-temperature superconducting (HTS) magnets are enabling more compact designs, highlighted in the IAEA's 2025 World Fusion Outlook.
Investment and Industry Trends
Fusion start-ups raised record funding in 2025 — the highest total since 2021 — with over $2.6 billion in private/public capital in the year to mid-2025 (total private investment now exceeds $9–10 billion globally, led by U.S. firms). This reflects a transition from lab research to prototype building and potential listings. Big Tech (Google, Microsoft, NVIDIA) is fueling demand via power purchase agreements and AI integration for modeling/plasma control.
Broader Landscape
The U.S. DOE released its Fusion Science & Technology Roadmap in October 2025, outlining a "Build–Innovate–Grow" strategy to close gaps (materials, fuel cycles, plasma systems) and support commercial plants by the mid-2030s.
Globally, over 160 fusion facilities exist or are planned. ITER continues as the flagship international project (major components arriving, first plasma delayed but progress steady).
The IAEA and others note fusion's rise as a national priority for clean, baseload energy amid AI/data center power demands and climate goals.
Fusion is no longer "30 years away" in perception — it's entering a decisive implementation phase, though engineering challenges (e.g., sustained net gain, tritium breeding, extreme materials) persist. 2026 could see further demos from private players and continued record-setting experiments.

Concise summary of the Financial Times article (February 11, 2026):
Headline: Fusion funding deals hit record as start-ups move from labs to listings
Core points:
Nuclear fusion start-ups completed a record number of funding rounds in 2025, raising the highest total investment since the 2021 peak.
This surge reflects growing investor confidence in fusion as a source of cheap, abundant clean power, with the sector perceived as nearing commercial viability.
The industry is transitioning from primarily lab/research-focused development to more mature stages, including prototype building and preparations for public listings (e.g., potential IPOs or market debuts).
The full article is paywalled, so specific figures, named companies, or individual deal details aren't publicly available in the accessible portions. This aligns with broader 2025 trends of accelerating private capital inflows into fusion amid breakthroughs and energy demands.

What fusion companies have gone public in 2025? Provide a chain of thought.
No pure-play nuclear fusion companies completed a full public listing (e.g., traditional IPO or completed SPAC merger) in 2025.
The Financial Times article from February 11, 2026, discusses fusion start-ups "moving from labs to listings" amid record 2025 funding, signaling preparations and momentum toward public markets—but no actual 2025 completions are mentioned in available sources.
Key developments around public paths in late 2025/early 2026:
TAE Technologies announced a major all-stock merger with Trump Media & Technology Group (NASDAQ: DJT, ticker for Truth Social's parent) on December 18, 2025. This deal valued the combined entity at around $6 billion and aimed to create one of the first publicly traded companies with a strong fusion focus. However, as of February 2026, sources describe it as "agreed" or "announced," with no confirmation of closure in 2025—typical SPAC/reverse-merger timelines often extend into the following year for regulatory approvals and filings.
General Fusion (a Canadian magnetized target fusion company) announced a ~$1 billion SPAC business combination with Spring Valley Acquisition Corp. III (NASDAQ: SVAC) on January 22, 2026. It was positioned as potentially becoming the "first publicly traded pure-play fusion company" upon closing (expected mid-2026), with trading under ticker "GFUZ." This occurred after 2025, so it doesn't count as a 2025 event.
Other leading players like Commonwealth Fusion Systems, Helion Energy, Zap Energy, and most others remained private throughout 2025, despite massive funding rounds (e.g., CFS raised $863M in 2025) and power purchase agreements with tech giants.
Chain of thought summary:
The query specifies 2025 events, aligned with the FT article's context of 2025 funding surges and transition to "listings."
Searched broadly for IPOs, SPACs, mergers, or public listings of fusion companies in 2025 ? no completed deals surfaced for that calendar year.
Late-2025 announcements (e.g., TAE-Trump Media in Dec 2025) represent planning/intent but not completion in 2025.
Early-2026 moves (e.g., General Fusion SPAC) confirm the "move to listings" trend the FT highlighted, but post-date 2025.
Consensus from sources (TechCrunch, Motley Fool, company announcements, industry reports): No fusion start-up went fully public in 2025; the sector was still in private fundraising/prototype phase, with public market access emerging in 2026.
If you're tracking potential 2026 listings or indirect exposure (e.g., via backers like Alphabet/Google or Chevron), let me know for more details! |
