13 July 2026: Annual funding for the fusion industry saw a record year of $4.48bn raised in the 12 months leading to July 2026, according to The Global Fusion Industry in 2026 Report by the Fusion Industry Association (FIA). The fusion sector has reported a total of $14.24bn since the annual survey began in 2021 and now employs over 16,000 people.  

Now in its sixth year, the report aims to provide a comprehensive view of fusion sector growth and progress towards commercial fusion. This year, the FIA surveyed 56 fusion companies – up from 23 in 2021 – with six new entrants since last year, while three companies withdrew. 

This year’s figures include major funding rounds such as Commonwealth Fusion Systems (CFS), which raised an $863m Series B2 round in August 2025; Inertia Enterprises, which raised a $450m Series A in February 2026; Helion Energy, which raised $465m in June 2026; and Proxima Fusion, which raised $518m in July 2026. 

Also included this year, for the first time, was incoming investment from companies announcing plans to join the public markets. Two companies, TAE Technologies and General Fusion, are preparing to join the Nasdaq exchange in 2026 and both received hundreds of millions of dollars in new investment as part of the process of going public. Their participation in the stock market demonstrates increasing confidence in commercial fusion, bringing new investment, along with a different type of scrutiny to the sector.
