China's FUSION THz raises hundreds of millions for fusion diagnostics, nears unicorn status
What's the deal? FUSION THzDealroom has a profile for this one. Try Dealroom →, a Chinese fusion-technology company, has closed a late-stage equity round worth several hundred million yuan, led by Guoshou Capital. The financing pushes its post-money valuation into the billions of yuan, placing it in near-unicorn territory.
Who's backing it? The round drew a roster of hard-tech investors alongside lead backer Guoshou Capital: SMIC Capital, Zhongwei CapitalDealroom has a profile for this one. Try Dealroom →, Yongjun Capital, Jinyan Capital, Lvjixing, and listed company KDIT IntelligentDealroom has a profile for this one. Try Dealroom →.
What does it do? The company was spun out of the Chinese Academy of Sciences' Hefei Institutes of Physical Science, built on technology from the EAST superconducting tokamak — the experimental reactor nicknamed China's "artificial sun." It develops terahertz diagnostic systems that measure core plasma parameters, such as electron density, without physical contact.
Why it matters: Those measurements are central to running fusion reactors safely and steadily. The systems provide the real-time, high-precision sensing needed for feedback control of high-temperature plasma, a step toward making fusion energy commercially viable.
The signal: The breadth of the investor list — state-linked funds, semiconductor capital, and a listed industrial firm — signals growing conviction that fusion supply-chain plays, not just reactors themselves, are worth backing. Diagnostics and sensing are emerging as an investable niche within China's push toward fusion industrialisation.
