- • CEO Francesco Sciortino stated the round demonstrates "Europe can not only invent breakthrough technologies, but also build globally competitive companies around them," highlighting the continent's competitive advantage in fusion innovation.
- • The investment reflects institutional confidence in stellarator fusion technology as a commercially viable path to clean, abundant energy without radioactive waste or greenhouse gas emissions.
Summary
Proxima Fusion, a Munich-based magnetic fusion startup, has secured €411 million in a major financing round, reaching a valuation of €2.4 billion. The round was led by venture capital firms XTX Ventures and East X Ventures, with strategic participation from Alphabet's Google and RWE, Germany's largest utility company. RWE invested €25 million as part of the round, underscoring institutional utility sector confidence in the technology.
The financing represents a significant milestone for stellarator fusion development, the largest private investment in stellarator technology to date. This capital infusion enables Proxima to accelerate construction and testing of its Stellarator Model Coil, scheduled for completion by 2027. The company's total funding now exceeds €185 million in combined private and public capital.
A key strategic element of the investment is RWE's commitment to partner with Proxima on developing the first commercial stellarator fusion power plant. The facility will be constructed at Gundremmingen, Bavaria, on the site of a decommissioned nuclear fission power station. This partnership pairs venture-stage technology development with utility-scale infrastructure expertise and existing grid infrastructure, a critical advantage for commercialization timelines.
Proxima Fusion's chief executive, Francesco Sciortino, emphasized the geopolitical and competitive dimensions of the achievement, noting that the round validates Europe's capacity to both innovate breakthrough technologies and scale them into globally competitive enterprises. The investment arrives amid growing institutional recognition that fusion energy—which replicates the sun's reaction through magnetic confinement—offers a pathway to abundant, clean electricity without radioactive waste or greenhouse gas emissions. The German government has committed over €2.4 billion in public investment over the next three years under its Fusion Action Plan, further validating the sector's strategic importance.
