Amazon-backed nuclear startup X-energy has officially launched plans to raise up to $800 million through an initial public offering, positioning itself at the center of a rapidly growing race to power the next generation of artificial intelligence infrastructure.
The Maryland-based company is offering roughly 42.9 million shares priced between $16 and $19 each, which could generate as much as $814 million and value the company at about $7.5 billion if investor demand holds strong.
The IPO marks a significant moment not just for X-energy but for the broader nuclear energy sector, which is experiencing renewed investor interest after years of stagnation. At the core of this resurgence is a simple reality: the global surge in AI and data centers is driving an unprecedented demand for reliable, carbon-free electricity.
X-energy specializes in small modular reactors, often referred to as SMRs, which are designed to be smaller, safer and more cost effective than traditional nuclear plants. These reactors can be deployed faster and scaled more flexibly, making them particularly attractive for industrial users and tech companies seeking stable power supplies.
The company’s flagship technology, the Xe-100 reactor, is a high temperature gas cooled system that uses advanced fuel designed to improve safety and efficiency. Unlike conventional nuclear plants, these reactors are modular, meaning they can be built in factories and assembled on site, reducing construction time and cost.
X-energy’s growth has been heavily supported by strategic partnerships, most notably with Amazon. The tech giant has invested hundreds of millions of dollars into the company and plans to deploy more than 5 gigawatts of nuclear capacity using its technology in the coming years.
That partnership highlights a broader shift in the energy landscape. Big Tech companies, including Amazon, Google and Microsoft, are increasingly turning to nuclear energy as a solution to the massive power demands created by AI systems and hyperscale data centers. Unlike renewable sources such as solar and wind, nuclear energy provides constant, baseload power, making it more suitable for energy intensive computing operations.
The timing of the IPO is also strategic. After a volatile start to the year marked by geopolitical tensions and market uncertainty, investor confidence has begun to return, with stock markets reaching record highs and IPO activity showing signs of revival.
X-energy had previously attempted to go public through a special purpose acquisition company in 2023 but abandoned the plan due to unfavorable market conditions. The decision to pursue a traditional IPO now suggests that the company sees a more favorable environment and stronger investor appetite for energy transition technologies.
Beyond funding, the IPO is expected to support the company’s long term ambitions. X-energy is working to deploy more than 11 gigawatts of nuclear capacity across the United States and the United Kingdom, with initial projects already underway in Texas and Washington state.
However, the path forward is not without risks. Despite strong backing and technological promise, commercial deployment of small modular reactors is still in its early stages. Regulatory approvals, construction timelines and cost overruns remain key uncertainties that could affect the company’s future performance.
There is also the question of market timing. While demand for clean energy is rising, nuclear projects typically require significant upfront investment and long development cycles. Investors will be betting not just on X-energy’s technology, but on its ability to execute in a sector known for delays and complexity.
Still, the broader trend is undeniable. Governments and corporations alike are re evaluating nuclear energy as part of the global transition to low carbon power. The International Energy Agency has projected that nuclear capacity will need to expand significantly to meet climate goals while supporting growing electricity demand.
For X-energy, the IPO represents more than just a fundraising event. It is a test of whether capital markets are ready to fully embrace nuclear technology as a cornerstone of the future energy mix.
If successful, the listing could open the door for other advanced nuclear startups to follow, accelerating investment into a sector that is rapidly moving from experimental to essential.
In a world increasingly powered by data and artificial intelligence, the question is no longer whether energy demand will rise. It is how it will be met. X-energy is betting that nuclear power will be a big part of the answer.
