Google Backs Germany’s Proxima Fusion in €411M Funding Round
Google-backed Proxima Fusion raised €411 million in a financing round that values the Germany-based startup at about $2.7 billion, setting its sights on building Europe’s first commercial fusion power plant. The funding will accelerate production of high-temperature superconducting magnets and engineering systems for Proxima’s stellarator approach as it targets a demonstrator in the early 2030s.
Key Takeaways
- Proxima Fusion raised €411 million and is valued at roughly $2.7 billion.
- The round was led by XTX Ventures and East X Ventures, with Google and RWE as strategic investors and participation from Plural, UVC Partners, Balderton and Cherry Ventures.
- Proxima is developing stellarator fusion technology and plans to scale high-temperature superconducting (HTS) cable and magnet production.
- The company targets a fusion demonstrator in the early 2030s and a commercial plant later in the decade.
- Google already backs U.S. fusion player Commonwealth Fusion Systems and has an offtake deal for CFS’s first commercial plant, signaling a broader strategic push into fusion.

MarketMoodz Analysis
For investors, Proxima’s €411 million raise is a clear signal that strategic capital—from a tech giant and a major utility—is moving aggressively into long-horizon energy R&D. The funding underwrites near-term industrial bets: scaling high-temperature superconducting (HTS) cable and magnet production and building engineering and manufacturing systems for stellarators. Those supply-chain plays—precision magnet manufacturing, cryogenics and superconducting materials—could create investable opportunities well before a commercial fusion plant sells a single megawatt-hour.
The round also repositions Europe in the global fusion race. U.S. peers like Commonwealth Fusion Systems (about $2.9 billion raised to date) and Helion Energy (roughly $1.5 billion raised, including a recent $465 million round) have dominated headlines; Proxima’s roughly $2.7 billion valuation puts it squarely among the highest-valued private fusion companies. Stellarators offer an alternative technical route to tokamaks and carry different engineering trade-offs—more complex magnet geometries but potentially steady-state operation—so success would broaden the technological pathway to commercial fusion and diversify market leaders.
What to watch next: delivery of the promised demonstrator in the early 2030s, the company’s ability to scale HTS magnet production, and commercial tie-ups or offtake agreements with utilities and large industrial buyers. Timelines for fusion demonstrations have historically slipped, and regulatory, siting and safety reviews will shape deployment. Still, the presence of strategic investors like Google and RWE raises the probability of early commercial partnerships and gives Proxima a clearer route to test and integrate its technology with grid and industrial customers.
