X-energy Launches IPO Roadshow Targeting $800M

X-energy, the nuclear startup backed by Amazon, has formally launched its IPO roadshow with plans to raise up to $800 million, according to its filing. The company is now actively pitching prospective investors as it moves toward a public listing. X-energy develops small modular reactors and advanced nuclear fuel technology, positioning itself within a sector drawing renewed institutional and corporate interest. Amazon's backing lends the offering a degree of credibility that pure-play nuclear startups have historically struggled to secure from public markets. The IPO size, at up to $800 million, would represent a substantial capital raise for the advanced nuclear space, providing X-energy with a runway to advance reactor development and commercialization. Investors will be watching whether demand at that valuation holds given the capital-intensive, long-lead nature of nuclear projects and the wider reset in growth-stock appetite. Pricing and timing details were not disclosed in available reporting.
