Nuclear Fusion Market Report 2026

The nuclear fusion market size is expected to see steady growth in the next few years. It will grow to $178.02 billion in 2030. The growth in the forecast period can be attributed to increasing private sector funding in fusion energy, advancements in reactor efficiency and stability, growing demand for carbon-free baseload power, expansion of pilot fusion power plants, progress toward net energy gain milestones. Major trends in the forecast period include advancements in magnetic confinement reactor designs, growing investment in private fusion startups, expansion of high-powered laser fusion systems, increasing use of ai in plasma control, enhanced focus on commercial fusion viability.

The growth of the nuclear fusion market is anticipated to accelerate due to increased government funding for nuclear energy. Nuclear energy is generated by splitting atoms in a reactor, producing steam to drive turbines and generate electricity. Numerous developed countries are investing in nuclear reactors, thereby boosting demand in the nuclear fusion market. For example, in January 2024, the Sunak Conservative government in the UK announced an extensive plan to quadruple the nation’s nuclear capacity by 2050, targeting a total of 24 gigawatts (GW). This initiative, part of the Civil Nuclear Roadmap, aims to enhance energy independence and security, lower electricity bills, and create jobs within the nuclear sector. The government intends to invest up to £300 million ($389.5) in the domestic production of high-assay low-enriched uranium (HALEU) and is dedicated to constructing new large-scale reactors, alongside developing small modular reactors (SMRs) as part of this nuclear resurgence. Thus, increased government funding for nuclear energy is propelling the growth of the nuclear fusion market.

Key players in the nuclear fusion market are forming strategic partnerships to address the intricate challenges of nuclear fusion energy production. These collaborations allow companies to leverage combined expertise, share resources, and foster technological advancements, thereby accelerating the path toward sustainable and commercially viable fusion energy. For instance, in January 2023, First Light Fusion, a UK-based fusion company, entered into an agreement with the United Kingdom Atomic Energy Authority, a government department in the UK, to design and construct 'Machine 4,' a facility aimed at hosting their new net energy gain demonstrator.

In March 2024, Vistra Corp, a US-based electricity generation company, completed the acquisition of Energy Harbor Corp. for an undisclosed sum. This acquisition enables Vistra to enhance its portfolio by adding approximately 4,000 megawatts of nuclear generation capacity and gaining around 1 million retail customers. Energy Harbor Corp., also based in the US, is an energy supplier that specializes in providing carbon-free and green electricity plans to residential and commercial clients across several states.
