X-energy has secured a $700 million Series C-1 funding round, backed by investors such as Segra Capital Management, Jane Street, Ares Management, Emerson Collective, and Amazon’s Climate Pledge Fund. This financing will accelerate the development of the company’s advanced small modular reactors (SMRs) and TRISO-X fuel technology, furthering its mission to provide clean, reliable, and scalable energy solutions. Founder and Executive Chairman Kam Ghaffarian emphasized that the funding will support the completion of X-energy’s reactor design, secure necessary licensing, and advance its TRISO-X fuel fabrication facility in Oak Ridge, Tennessee. As global energy demands rise, this investment positions X-energy to expand its impact in the next generation of nuclear energy.
Additionally, the financing will support future carbon-free projects powered by X-energy’s Xe-100 SMRs, which deliver 80 megawatts (MW) of electricity per unit and can scale from 320 MW to 960 MW through multi-unit plants. The modular, road-shippable design of the Xe-100 reactors aims to simplify construction, reduce costs, and enable scalability across regions. X-energy is currently developing its first Xe-100 plant at Dow’s UCC Seadrift Operations site in Texas, supported by the U.S. Department of Energy’s Advanced Reactor Demonstration Program. Amazon and X-energy also plan to bring over five gigawatts of new power projects online in the U.S. by 2039. Their collaboration focuses on direct project investments and long-term power purchase agreements, aiming to meet rising energy demands while establishing a model for future infrastructure partnerships. This funding reinforces X-energy’s position in the clean energy sector and highlights growing investor interest in advanced nuclear technology as a sustainable energy solution.
