This Week’s Fusion News: June 5, 2026
June 5, 2026
Helion closed a $465 million Series G led by Thrive Capital at a $15.5 billion valuation, the largest fusion VC round of 2026. The raise moves Helion to #2 on The Fusion Report’s Top Fusion Companies by Funding tracker, now at ~$11.4 billion across 24 companies. Xcimer Energy began operations at Phoenix, a krypton fluoride excimer laser system in Denver and the prototype for its commercial laser fusion architecture. And The Fusion Report examines whether ITER remains relevant as its cost climbs toward $24 billion and completion slips to 2039, while commercial machines like CFS’s ARC target 400 MW in the early 2030s.
Xcimer Energy Announces the Start of Operations for Its Phoenix Laser System Facility

The new Ferrari Luce is a $640K, 1,035-hp, five-seater sedan that isn’t red, isn’t especially pretty, and isn’t even the fastest EV sedan on the market. So why does it matter? Because when Maranello commits to electrification, the rest of the supercar world has to take EV adoption seriously, and that has knock-on effects for every kilowatt-hour of electricity we’ll need to generate in the decade ahead.
The Fusion Report sized up where battery energy storage technology is headed and asked whether the next generation of AI-powered robots will run on fusion. The NRC is moving toward a substantially lighter federal review of fusion, Germany joined the EU’s IPCEI on innovative nuclear technologies for fusion only, Singapore’s A*STAR signed a five-year research pact with CFS, Canada backed a fusion-based copper-67 isotope production project, General Fusion brought on capital markets veteran Thomas Boehlert as it prepares for the public markets, and JT-60SA cleared its upgrade cycle and prepared for restart.
Will Next-Generation Artificial Intelligence Robots be Powered by Fusion Energy?
/ May 21, 2026
Fusion and AI-powered robots have crossed paths in fiction since 1927’s Metropolis, with Iron Man’s Arc Reactor and the Terminator’s atomic batteries pushing the idea into popular culture. The Fusion Report looks at what it would actually take to drop a fusion device inside a robot. Avalanche Energy’s Orbitron, CFS SPARC, and Helion’s 19-meter machine all clear the power output bar. The size bar is a different story. Fusion can power the grid that powers the robots. A Terminator with a fusion machine in its chest is a longer wait.
Where is Battery Energy Storage System Technology Going?
/ May 19, 2026
US grid-scale BESS capacity is now 45 GW, and California alone added 16.9 GW since 2018. Lithium-ion still leads, riding the EV cost curve, but sodium-ion, vanadium redox flow, and iron-air batteries each have a distinct play in stationary storage. Each technology fits a different point on the duration, safety, and cost curves.
Thea Energy operated its first full-scale stellarator shaping coil, and The Fusion Report dug into whether $50/MWh is really the bar for commercial fusion in the US. Fusion lands on China’s 15th Five-Year Plan as a frontier priority, ITER explains how fusion is pushing AI to evolve, Xcimer Energy keeps stacking senior hires, and Stellarex Energy and TAE Technologies both add new joint work with UKAEA.
Thea Energy Announces Successful Operation of Full-Scale Planar Shaping Coils
/ May 14, 2026
Thea Energy has successfully operated its first full-size, full-current, full-field stellarator planar shaping coil at over 6 T and 20 K, hitting Eos-spec performance. The milestone validates the company’s software-controlled magnet approach and its in-house build in Kearny, NJ, where a second facility is planned for 2026 to scale shaping coil production.
How Real is the Need To Hit $50 per Megawatt-Hour for Fusion Energy to Succeed In the US?
/ May 12, 2026
Bob Mumgaard, CEO of Commonwealth Fusion Systems, said fusion needs to hit $50/MWh to succeed. But US wholesale prices swing from $24 to $260/MWh by region, Europe and Japan run $95 to $100/MWh. AI data centers paying behind the meter face $150 to $300/MWh. $50/MWh is a goal, not a requirement. The real bar is facility Q>10.
Type One Energy, Tokamak Energy and Construction Giant AECOM Form the UK Infinity Fusion Consortium
/ May 7, 2026
Type One Energy, Tokamak Energy, and AECOM have formed the UK Infinity Fusion Consortium, a private-sector-led effort to build a 400 MWe stellarator-based fusion power plant in the United Kingdom by 2034. The plant is the second to use Type One Energy’s stellarator design and the second fusion plant announced for the UK, after the STEP tokamak.
