X-Energy, Inc. Class A Common Stock, XE
Momentum carried into the next week as shares added roughly 16% during Monday’s premarket session. The combined movement represents substantial appreciation within the first two trading periods.
The offering was structured to bring in $1 billion, attracting participation from Amazon and Ken Griffin, the founder behind Citadel hedge fund. When Friday’s bell rang, X-Energy’s valuation stood at $11.6 billion.
X-Energy specializes in modular nuclear reactor technology designed to deliver electricity to manufacturing plants and data centers. Current customers include Dow, Inc. alongside Amazon.
The firm enters a competitive field of nuclear and alternative energy companies aligning themselves with AI infrastructure requirements. Oklo (OKLO) and Fermi (FRMI) represent other players in this sector, though both experienced declines on Monday, falling 7.15% and 9.04% respectively.
Amazon’s strategic participation stems from its requirement for dependable, environmentally friendly electricity sources to power AWS infrastructure. With AI computing demands expanding throughout these facilities, securing adequate power has evolved into a critical operational priority.
Financial Performance
X-Energy generated $109.3 million in revenue during 2025. The company simultaneously recorded a $390 million net loss over this period, characteristic of the capital-intensive phase of developing nuclear reactor capabilities.
The modular reactor platform remains in expansion mode, with the trajectory toward positive earnings heavily influenced by the company’s ability to finalize and deliver on substantial energy agreements with anchor clients such as Amazon.
Competitive Landscape with Strong Demand
The artificial intelligence expansion has driven energy consumption forecasts considerably higher, positioning nuclear power as a prominent candidate given its consistent output and minimal carbon emissions.
X-Energy’s public offering introduces a fresh ticker to this narrative, distinguished by an established commercial partnership with a leading global cloud infrastructure provider.
While Amazon’s involvement lends significant validation, it simultaneously introduces questions regarding revenue diversification if this relationship becomes disproportionately large within the overall business mix.
The robust debut performance indicates strong investor interest in the nuclear-AI energy intersection continues, despite weakness observed in comparable stocks on Monday.
During Monday’s premarket session, XE traded approximately 16% higher, extending beyond Friday’s 27% opening-day advance.
