X-Energy, Inc. Class A Common Stock, XE
Momentum extended into the next week, with shares advancing roughly 16% in Monday’s premarket session. This pushed the total gain substantially above the IPO price in less than two full trading days.
The nuclear energy firm priced its offering to capture $1 billion, attracting investments from Amazon and Ken Griffin, the billionaire behind Citadel. When Friday’s session concluded, X-Energy commanded an $11.6 billion market capitalization.
X-Energy deploys modular nuclear reactor systems to deliver electricity to data centers and industrial operations. Major customers include Dow, Inc. alongside Amazon.
The firm enters a broadening field of nuclear and energy companies aligning themselves with AI infrastructure requirements. Competitors like Oklo (OKLO) and Fermi (FRMI) operate in similar territory, though both experienced declines on Monday, falling 7.15% and 9.04% respectively.
Amazon’s investment stems from its requirement for dependable, carbon-neutral power sources to operate AWS data center networks. With AI processing loads expanding across these facilities, securing adequate electricity has evolved into a critical operational challenge.
Financial Performance
X-Energy generated $109.3 million in revenue throughout 2025. The company simultaneously recorded a $390 million net loss during the period, highlighting the developmental stage of establishing nuclear reactor operations.
The firm’s modular reactor approach remains in expansion mode, with the route to positive earnings heavily reliant on obtaining and fulfilling extended energy supply agreements with major clients such as Amazon.
Competitive Landscape Amid Rising Demand
The artificial intelligence revolution has pushed energy consumption forecasts dramatically upward, positioning nuclear power as a prominent solution given its consistent output and minimal carbon emissions.
X-Energy’s public listing introduces another tradable option within this narrative, particularly one maintaining a direct business connection with a leading global cloud infrastructure provider.
While Amazon’s endorsement provides validation, it simultaneously introduces concerns regarding revenue dependency if the Amazon relationship comprises a disproportionate share of incoming contracts.
The stock’s robust debut indicates continuing investor enthusiasm for the nuclear-AI energy intersection, despite weakness among certain competitors on Monday.
During Monday’s premarket session, XE traded approximately 16% higher, extending Friday’s impressive 27% opening day performance.
