X-Energy Raises Another $700 Million to Accelerate SMR Deployment
X-Energy has closed an oversubscribed $700 million Series D round led by Jane StreetDealroom has a profile for this one. Try Dealroom → that will support the company’s efforts to commercialise its advanced small modular reactor (SMR) technology.
The new funding follows another $700 million round anchored by Amazon in early 2025, which supported final reactor design work, licensing efforts and construction of a dedicated fuel-production facility.
The company’s high-temperature, gas-cooled SMR is designed for industrial power, chemical production and AI-driven data-centre operations—sectors facing mounting pressure to secure reliable, low-carbon energy.
Early deployment projects include supplying heat and power to DowDealroom has a profile for this one.

X-Energy’s commercial pipeline now exceeds 11 gigawatts , equivalent to around 144 planned SMR units , reflecting rising interest amid a broader revival of the US nuclear sector.
Electricity demand driven by cloud computing and artificial intelligence has ended decades of flat growth in US power consumption, prompting companies and utilities to revisit nuclear options that can be built and deployed more quickly than traditional large reactors.
For X-Energy, this shift represents an opportunity to position its small modular reactors as a practical source of reliable, low-carbon baseload power—supporting both industrial customers and the emerging energy requirements of the AI economy.
