Proxima Fusion Raises 411 Million Euros

European fusion energy is making headlines once again. Munich-based deep-tech company Proxima Fusion has closed a funding round of 411 million euros. This brings the startup’s total funding to more than 650 million euros and its valuation to 2.4 billion euros. According to the company, this makes Proxima the best-funded fusion company in Europe.

The funding round also ranks among the largest private technology investments of the year in Europe and marks the largest private capital round to date in the European fusion sector.

Broad Consortium of Investors Bets on Fusion Energy

The round was led by XTX Ventures and East X Ventures. Energy conglomerate RWE and Google are also participating as strategic investors.

In addition, KfW Capital, SPRIND, and Burda Principal Investments are investing alongside numerous existing investors, including Plural, UVC Partners, Balderton, Cherry Ventures, DST Global Partners, Lightspeed, DTCF, Bayern Kapital, and the EIC Fund.

The international investor community has sent a strong signal: It has confidence not only in Europe’s scientific excellence but also in our ability to build globally competitive industrial companies based on that excellence.

RWE’s investment is particularly noteworthy. Just a few months ago, the energy company, together with Proxima Fusion, the Free State of Bavaria, and the Max Planck Institute for Plasma Physics, announced plans to develop Europe’s first stellarator fusion power plant on the site of the former Gundremmingen nuclear power plant.

Google is also participating in the funding round, underscoring the growing interest among major technology companies in nuclear fusion as a potential source of CO₂-free and sustainably available energy.

Alpha is set to pave the way for the first fusion power plant

Proxima Fusion plans to use the new capital to finance the construction of “Alpha”—a demonstrator for a stellarator fusion system near Munich.

The project is considered a crucial intermediate step between decades of basic research and the commercial use of fusion energy. The goal is to validate key technologies for future power plants under real-world conditions and to lay the groundwork for the development of a commercial fusion power plant still within this decade. To this end, Proxima is working closely with the Free State of Bavaria, the Max Planck Institute for Plasma Physics, and RWE.

Europe in a Race with the U.S. and China

The funding also underscores the growing global competition for the commercialization of fusion energy. While in recent years it was primarily U.S. companies that were able to secure funding in the billions, Europe is now increasingly positioning itself as an independent hub of innovation.

According to Proxima founder and CEO Francesco Sciortino, the coming years will determine which regions develop the first commercially viable fusion power plants and thereby secure long-term technological and industrial leadership positions.

The current round of funding demonstrates that Europe is not only capable of producing cutting-edge scientific research but is also increasingly building companies with global ambitions.

From Research Project to Industrial Company

Since its founding less than three years ago, Proxima Fusion has already raised more than 650 million euros, including approximately 95 million euros in public funding. With this new funding, the company now aims to accelerate the development of its superconducting magnet technology, the construction of a model coil for the stellarator, and the expansion of its own production and manufacturing capacities.

At the same time, Proxima Fusion plans to significantly expand its workforce at its locations in Germany, Switzerland, and the United Kingdom.

Europe’s Next Deep-Tech Champion?

This funding round is more than just a success for a single startup. It shows that companies are increasingly emerging in Europe that can attract billions in investments even in capital-intensive future technologies.

Whether Proxima Fusion will actually build Europe’s first commercial fusion power plant remains to be seen. One thing is clear, however: the race for the energy source of the future has long since begun—and Europe does not intend to merely watch from the sidelines but rather to take a leading role with its own technology champions.
