Amazon-backed nuclear startup X-energy has launched its IPO roadshow, offering 42.9 million Class A shares at $16 to $19 each in a deal that could raise as much as $814.3 million. The move puts one of the most closely watched advanced nuclear companies in front of public-market investors as electricity demand rises with AI data center growth and wider industrial electrification.
TL;DR
- X-energy has started its IPO roadshow with shares priced between $16 and $19.
- At the top of the range, the offering could raise about $814.3 million.
- Amazon is both a major backer and a strategic partner in future nuclear deployment plans.
- The company is pitching advanced nuclear as a reliable power source for AI-era electricity demand.
- The filing also shows a capital-intensive business with sizable losses and long execution timelines.
What Did TechCrunch Actually Report?
TechCrunch reported that X-energy began pitching investors on Wednesday and is seeking to raise up to roughly $814 million through its initial public offering. The report also noted that Amazon is among X-energy’s largest supporters, and that the timing reflects renewed investor interest in nuclear power as data centers consume more electricity.
That narrower framing matters. This is not a story about completed reactor deployment or guaranteed near-term commercialization. It is a story about a startup trying to convert growing enthusiasm around nuclear energy into public-market capital at a moment when reliable, around-the-clock power has become more valuable to technology and industrial buyers.
What Does The Filing Show?
X-energy said it is offering 42,857,143 shares of Class A common stock and expects to trade on Nasdaq under the ticker XE. Reuters reported that the top end of the pricing range would imply a valuation of up to $7.51 billion, underscoring how aggressively investors may price companies tied to next-generation energy infrastructure.
The filing also tempers some of the broader speculation around the deal. Rather than tying the IPO money to a narrow list of deployment milestones, X-energy said the net proceeds are expected to support working capital and general corporate purposes. These include research and development, sales and marketing, capital expenditures, supply chain and procurement activity, and future growth projects.

How Does Amazon Fit In?
Amazon’s role extends beyond equity backing. In October 2024, X-energy said Amazon anchored a $500 million Series C-1 financing round and that the two companies aimed to bring more than 5 gigawatts of new power projects online in the United States by 2039. The companies also said they would initially support a four-unit, 320-megawatt project with Energy Northwest in central Washington.
At the time, X-energy CEO J. Clay Sell said, “Amazon and X-energy are poised to define the future of advanced nuclear energy in the commercial marketplace.” Amazon Vice President of Global Data Centers Kevin Miller said X-energy’s technology would help bring “new sources of carbon-free energy to the grid cost-effectively and safely.”
Why This IPO Matters
X-energy is developing the Xe-100, a high-temperature gas-cooled reactor, along with TRISO fuel. The company’s S-1 also shows the financial strain of building in a sector known for long timelines and high capital needs. X-energy reported a 2025 net loss of $389.8 million, compared with $126.0 million a year earlier, while cash and cash equivalents stood at $458.9 million at year-end.
So the real test is not whether nuclear power sounds attractive in the AI era. It is whether public investors are ready to keep funding a developer that still faces regulatory, technical, and commercial hurdles, even with Amazon’s support and a more favorable narrative around clean baseload power.
