The fusion energy industry notched several advances this week as startups reached technical milestones, a federal roadmap charted the path to commercialization, and suppliers expanded operations in anticipation of what the Financial Times reported could become a $73 billion market.prnewswire+1

Avalanche Hits Temperature Milestone

Seattle-based Avalanche Energy announced on June 10 that its compact fusion device, Jyn, achieved measured ion temperatures exceeding 1 kiloelectron volt — roughly 11 million degrees Celsius, comparable to temperatures found in the core of the Sun. Only a handful of fusion companies have reached such temperatures. TechCrunch, which received an exclusive briefing, reported that the milestone suggests the startup is on a credible path toward conditions that could spark net-energy fusion reactions. Avalanche raised $29 million in February led by RA Capital Management.avalanchefusion+2

CFS and Tokamak Energy Advance Reactor Builds

Commonwealth Fusion Systems, the world's best-funded private fusion company with roughly $3 billion raised, reported in April that its SPARC tokamak facility in Devens, Massachusetts is approximately 75 percent complete. The company targets first plasma in 2026 and aims to demonstrate net energy gain in 2027. Its commercial ARC power plant is planned for Virginia in the early 2030s.thefusionreport.substack+2

Tokamak Energy, meanwhile, is executing a $52 million upgrade to its ST40 spherical tokamak, jointly funded by the U.S. Department of Energy and the UK's Department of Energy Security and Net Zero. The five-year program, announced in late 2024, introduced all-metal plasma-facing components at the end of 2025. The company has also expanded into high-temperature superconductor applications for data centers and propulsion.tokamakenergy+3

Suppliers and Federal Strategy Signal Scale-Up

The Financial Times reported on June 12 that suppliers to the fusion industry are expanding capacity, betting the race to build reactors will create a $73 billion market. The Fusion Industry Association found that supply chain spending by fusion companies grew 73 percent to $434 million in 2024 and was projected to rise another 25 percent in 2025.world-nuclear-news+3

Reinforcing the momentum, the DOE on June 10 released its finalized Fusion Science and Technology Roadmap, a national strategy developed with input from more than 800 experts aimed at deploying fusion pilot plants by the mid-2030s. The plan consolidates infrastructure investment, workforce development, and supply chain seeding under the department's new Office of Fusion.energy+3
