Funding Round and Valuation
Proxima Fusion, a Munich-based nuclear-fusion startup, closed a €411 million financing round that values the company at €2.4 billion. Lead investors were XTX Ventures and East X Ventures; participants included RWE AG (€25 million), Google (amount undisclosed), KfW Capital and the EU’s EIC Fund. Existing shareholders matched the lead investors, adding roughly €300 million.
Background and Policy Context
Germany ended its nuclear-power program in 2023 after the 2011 Fukushima disaster, shifting to renewable energy while promoting fusion as a long-term, emissions-free source. Fusion remains experimental worldwide, with no commercial plant in operation.
Key Figures and Technology
CEO Francesco Sciortino leads Proxima, which uses a stellarator—a twisted donut-shaped magnetic chamber—claimed to be more stable than tokamak or laser designs.
Timeline of Milestones
Proxima raised €130 million in 2025 (total secured capital > €650 million, including €95 million in public grants), announced the €2 billion Alpha demonstrator in February 2026 (with Proxima and Bavaria each covering one-fifth), and closed the €411 million round on July 7 2026, adding €150 million from lead investors.
Financial Snapshot
The round added €150 million from XTX Ventures and East X Ventures, with existing investors matching it. Public grants total €95 million; the German federal government and EU are expected to fund the rest of Alpha’s €2 billion budget. Proxima has secured over €650 million to date.
Strategic Significance
Proxima positions itself as Europe’s “best-funded” fusion venture, aiming to build a commercial plant in the 2030s on a decommissioned RWE nuclear site in Bavaria. U.S. rivals Commonwealth Fusion Systems and Helion Energy have raised nearly $3 billion, highlighting trans-Atlantic competition.
Official Statements & Responses
RWE confirmed its €25 million investment and the Bavarian site. Proxima said more than 90 % of its investors are European and described itself as the best-funded nuclear-fusion entity in Europe. Sciortino noted the remaining Alpha financing will come from Germany’s federal government and the EU. Google’s role was described as strategic, with no immediate plans to link the investment to data-center power needs.
Conflicting Reports & Gaps
Google’s exact contribution was not disclosed, leaving its stake size unclear. Proxima’s claim of being the “best-funded” European fusion company lacks independent verification, and the precise schedule for Alpha’s construction beyond cost sharing remains unspecified.

What’s Next
Construction of the Alpha demonstrator on the former RWE site is slated to begin soon, with financing split equally between Proxima and Bavaria. The company expects additional public funding to complete the €2 billion budget and targets operation of a full-scale fusion plant in the 2030s. Google’s broader fusion investments, such as a 200 MW power purchase from Commonwealth Fusion Systems, signal continued corporate interest.
