Proxima Fusion Funding Reaches €130M: A European Fusion Energy Breakthrough
Europe’s Proxima Fusion Secures €130M in Series A Funding
Proxima Fusion funding has made headlines after the German startup secured a massive €130 million Series A round, cementing its status as one of Europe’s most promising nuclear fusion companies. While most high-value fusion ventures are based in the U.S., Proxima is proving that Europe is ready to compete in the global clean energy race. The funding round—led by Balderton Capital and Cherry Ventures—brings the company’s total capital raised to over €185 million. This boost positions Proxima Fusion as a serious player aiming to commercialize stable and sustainable nuclear fusion energy.

This latest Proxima Fusion funding round is more than a financial milestone—it reflects global interest in energy independence. Fusion promises a virtually limitless source of clean power, and unlike traditional nuclear energy, it doesn’t depend on uranium or other imported fissile materials. That’s a critical advantage for Europe, which is seeking energy solutions that don’t rely on politically volatile supply chains. As CEO Francesco Sciortino said, fusion giants will emerge across geopolitical blocks by the early 2030s—and Proxima aims to be Europe’s contender.
A Big Leap: From Seed to Stellaris
Before this breakthrough, Proxima Fusion’s funding stood at just €20 million from its 2024 seed round. That changed after the company published a peer-reviewed paper outlining its design for a next-gen fusion reactor. Proxima’s approach is centered on stellarators—devices that use magnetic fields to trap hot plasma long enough for fusion to occur. These differ from traditional tokamaks in that they don’t require plasma currents, which increases safety and reliability. Their proprietary “Stellaris” design builds upon research from Germany’s Wendelstein 7-X—the world’s largest stellarator—to propose a more efficient, scalable reactor.
What’s Next for Proxima Fusion After €130M Funding
The oversubscribed Series A shows growing confidence in Proxima Fusion’s vision and progress. According to Sciortino, this round didn’t just attract capital; it brought in strategic partners equipped to support the company through its next phase. By reaching technical milestones faster than promised, Proxima has set the stage for long-term growth. With fresh funding, the startup will focus on refining Stellaris, expanding its team, and preparing for prototype deployment. If successful, Proxima Fusion could become a cornerstone of Europe’s future energy infrastructure—and a symbol of how science-backed innovation can address climate and security challenges alike.
