X-Energy, a nuclear energy company, is planning an initial public offering that could generate significant returns for early investors, including Amazon and billionaire Ken Griffin. The company previously abandoned a public listing less than three years ago, prior to the artificial-intelligence boom fueling a surge in energy demand.
The IPO comes as technology companies seek reliable, carbon-free power sources for data centers. AI systems require massive amounts of electricity, pushing firms like Amazon to invest in alternative energy solutions. X-Energy develops small modular nuclear reactors, which are seen as a scalable option for round-the-clock power.
Amazon has already partnered with X-Energy to help bring its reactor designs to market. Ken Griffin, founder of hedge fund Citadel, also holds a stake through investment firm Citadel Securities. The company’s valuation in its last private funding round was roughly $2 billion.
X-Energy’s earlier attempt to go public in 2021 failed due to weak market conditions. The company was then set to combine with a special-purpose acquisition company, but that deal was scrapped. Since then, the demand for clean, consistent energy has risen sharply.
The IPO could provide a cash infusion to advance X-Energy’s reactor projects. The company’s technology aims to operate at lower costs than traditional nuclear plants. It also offers safety features that reduce the risk of meltdown.
Wall Street analysts are watching the IPO closely, as it tests investor appetite for nuclear energy. The sector has gained renewed interest as governments and corporations push to cut carbon emissions. Nuclear power provides a steady supply without the intermittency of solar or wind.
If successful, the listing could pave the way for other nuclear startups to go public. Industry observers say the deal’s outcome may signal broader acceptance of advanced nuclear technologies. Investors will weigh the long-term potential against regulatory and operational risks.
