Every Fusion Startup That Has Raised Over $100M

Fusion Startups That Raised $100M+ in the Race for Clean Energy Which fusion companies have raised more than $100 million? As of early 2026, at least a dozen private fusion startups worldwide have crossed that milestone—many with backing from top-tier venture capital firms, tech billionaires, and even government partnerships. Driven by breakthroughs in AI, superconducting magnets, and computational modeling, fusion energy is no longer just a scientific pipe dream. It’s now a high-stakes tech race with global implications for climate, security, and energy independence.
