X-Energy Raises $1.02 Billion in IPO as Amazon-Backed Nuclear Startup Targets AI Data Centers

X-energy, a nuclear technology company based in Rockville, Maryland, has completed a major step forward. On April 23, 2026, the X-Energy priced its initial public offering on Nasdaq, and raised about $1.02 billion by selling 44.25 million Class A shares at $23 each. This amount beat the original target range of $16 to $19 per share. Shares will start trading today under the ticker symbol XE.

The strong demand shows growing investor interest in nuclear power for data centers. Tech companies need steady, clean electricity to run AI systems. X-energy develops small modular reactors that fit this need well.

What X-energy Brings to the Table

X-energy focuses on advanced nuclear designs. Its main product is the Xe-100 reactor. Each unit produces about 80 megawatts of electric power. A standard plant uses four modules to deliver 320 megawatts. The design uses helium gas for cooling instead of water. This high-temperature gas-cooled approach allows the reactor to run safely at higher temperatures.

The company also makes its own fuel called TRISO-X. This fuel consists of tiny particles coated in layers that contain radiation even under extreme heat. Experts consider it one of the safest nuclear fuels available. X-energy received a license to build its fuel factory in Oak Ridge, Tennessee. This step helps the company move closer to real-world projects.

The technology suits data centers because it provides constant power without carbon emissions. Data centers often need hundreds of megawatts. A four-module Xe-100 plant can match that load directly on site. It can also supply high-temperature heat for industry.

Strong Backing from Amazon and Others

Amazon plays a big role in X-energy’s story. In 2024, Amazon led a $500 million funding round and took board seats. The company also agreed to buy power from X-energy projects. Its goal is to secure up to 5 gigawatts of nuclear capacity by 2039. This commitment gives X-energy a clear customer path.

Other partners add strength. X-energy works with Dow on a project in Seadrift, Texas. Four reactors will supply both electricity and steam for chemical manufacturing. The U.S. Department of Energy supports this effort through its Advanced Reactor Demonstration Program. The plant aims to start in the early 2030s.

In Washington state, X-energy plans another four-reactor site with Energy Northwest. Amazon supports this effort too. Plans exist to expand it later. Additional talks include Talen Energy for sites in Pennsylvania to serve data centers in the PJM market.

X-energy also signed a deal with Korean companies — Korea Hydro & Nuclear Power and Doosan Enerbility. Together with Amazon, they aim to bring up to $50 billion in investments for U.S. projects and supply chains. This partnership could speed up manufacturing and deployment.

Why the Timing Matters

AI is driving huge growth in electricity use. Data centers already consume large amounts of power. Forecasts show this demand will keep rising fast. Many tech firms find it hard to rely only on wind and solar because those sources are not always available. Nuclear offers 24/7 power that fits data center needs.

X-energy is not alone in this space. Other advanced nuclear companies chase similar opportunities. Yet X-energy stands out with its helium-cooled design and proven fuel technology. The IPO success — pricing well above the range — reflects confidence that nuclear can help meet the AI energy boom.

Before going public, X-energy raised more than $1.8 billion privately. The latest IPO adds fresh capital. The company plans to use the money to finish reactor licensing, expand fuel production, and prepare for first deployments. Lead banks on the deal included JPMorgan, Morgan Stanley, Jefferies, and Moelis & Company.

The offering values X-energy at roughly $9 billion post-IPO. This is higher than the pre-IPO target of about $7.5 billion. Strong orders helped push the size and price higher. Underwriters also have a 30-day option to sell up to 6.64 million more shares.

What Comes Next

First commercial reactors remain years away. X-energy targets early 2030s for initial plants. The Nuclear Regulatory Commission continues reviewing designs. Construction, supply chains, and helium needs all require careful management.

Still, the momentum is clear. Public support for nuclear has grown. New laws like the ADVANCE Act help speed approvals. Tech giants continue signing nuclear deals to secure clean power.

For data center operators and energy planners, X-energy’s IPO offers useful signals. The 320-megawatt plant size matches many facility needs. Direct equity ties from customers like Amazon reduce some risks. The focus on both power and industrial heat opens extra markets.

Readers tracking the AI infrastructure wave should watch X-energy’s progress on licensing and project milestones. The company’s ability to deliver on time will test whether advanced nuclear can scale quickly enough to support data center growth.

As one industry report noted, data centers could drive nearly 20 percent of U.S. electricity demand growth in coming years. Reliable sources like the Xe-100 could play a key part in meeting that need without adding carbon.

X-energy’s move to public markets marks a milestone for the advanced nuclear sector. It turns private innovation into a listed company ready to address real energy challenges. Investors, tech leaders, and policymakers will follow its next steps closely.
