The momentum carried into the next trading week, with shares climbing approximately 16% higher during Monday’s premarket hours. This represents substantial appreciation from the IPO price across just two trading sessions.
The nuclear energy developer’s public offering generated $1 billion, attracting investment from Amazon and Citadel’s billionaire founder Ken Griffin. By the end of Friday’s session, the company’s valuation reached $11.6 billion.
X-Energy specializes in modular nuclear reactor systems designed to deliver electricity to industrial operations and data center facilities. The company counts major corporations like Dow, Inc. and Amazon among its customer base.
The firm enters a expanding field of nuclear and energy companies capitalizing on AI infrastructure power requirements. Similar players include Oklo (OKLO) and Fermi (FRMI), though both experienced declines Monday, dropping 7.15% and 9.04% respectively.
Amazon’s investment stems from its requirement for dependable, carbon-neutral power sources for AWS data center operations. With AI computational demands escalating within these facilities, securing adequate power supply has evolved into a critical operational challenge.
Financial Performance
X-Energy recorded $109.3 million in revenue during 2025. However, the company reported a $390 million net loss over the identical period, characteristic of companies in the early phases of developing nuclear reactor systems.
The firm’s modular reactor platform remains in expansion mode, with the route to positive earnings largely dependent on finalizing and delivering on substantial, multi-year power agreements with enterprise clients such as Amazon.
Competitive Landscape in Energy Sector
The artificial intelligence expansion has driven energy consumption forecasts significantly upward, positioning nuclear power as a leading contender due to its consistent output and minimal carbon emissions.
X-Energy’s public listing introduces another tradable option in this sector, distinguished by its established commercial partnership with a leading global cloud infrastructure provider.
While Amazon’s support lends substantial validation, it simultaneously presents questions regarding revenue dependency if the Amazon relationship accounts for a disproportionate share of incoming business.
The stock’s robust debut performance indicates continued investor enthusiasm for nuclear energy plays connected to AI infrastructure themes, despite weakness observed in competing stocks Monday.
During Monday’s premarket trading, XE shares advanced roughly 16%, extending Friday’s impressive 27% initial trading gain.
