• $700M in funding boosts X-energy’s efforts to commercialize advanced nuclear technology.
• New investors, including Segra Capital, Jane Street, and Ares Management, join Amazon’s Climate Pledge Fund.
• Expansion plans include completing reactor design, licensing, and fuel production in Tennessee.

X-energy has closed an upsized $700 million Series C-1 financing round to accelerate the development of its advanced small modular reactor (SMR) technology. The round includes new investors Segra Capital, Jane Street, Ares Management, and Emerson Collective, alongside previously announced backers like Amazon’s Climate Pledge Fund, Ken Griffin affiliates, and the University of Michigan.

Why it matters:

The funding positions X-energy as a leader in the SMR market, driving clean, scalable, and reliable nuclear energy solutions to meet growing power demands.

“We welcome our new investors along our journey to accelerate the development and deployment of advanced nuclear energy,” said Kam Ghaffarian, Ph.D., Founder and Executive Chairman of X-energy. “We look forward to continuing to advance and scale our technology.”

How the funds will be used:

• Technology Development: Finalizing the Xe-100 SMR reactor design and licensing.
• Fuel Production: Expanding the TRISO-X fuel fabrication facility in Oak Ridge, Tennessee.
• Carbon-Free Projects: Deploying the Xe-100 reactors for industrial and energy applications.

The Bigger Picture:

X-energy’s Xe-100 SMR technology offers 80 MW per unit, with potential expansion up to 960 MW. The road-shippable, modular design cuts construction timelines and enhances scalability.

Real-world application:

• Dow Partnership: X-energy is developing its first Xe-100 plant at Dow’s Texas Gulf Coast facility, marking the first grid-scale advanced nuclear reactor to power an industrial site in North America.
• Amazon Collaboration: Amazon and X-energy aim to bring over 5 gigawatts of new power online by 2039 through direct project investments and long-term power purchase agreements.

What’s next:

X-energy and its partners are working to standardize deployment models and expand financing structures to drive nuclear energy adoption at scale.
