Amazon-backed nuclear startup X-energy seeks up to $814m in IPO

The US nuclear reactor developer X-energy began its IPO roadshow amid rising power demand from AI data centers and electrification, according to an SEC filing.

It has set a target price range of US$16 to US$19 per share, which could raise up to US$814.3 million at the top end.

Investors have put about US$1.8 billion into the company, PitchBook data showed.

Amazon led a US$500 million series C-1 round while pledging to buy as much as 5 gigawatts of power from X-energy by 2039.

🧠 Food for thought

Implications, context, and why it matters.

X-energy’s IPO leans on federal support and progress on a fuel factory

  • X-energy has lined up up to US$1.2 billion in cost-sharing support from the U.S. Department of Energy’s Advanced Reactor Demonstration Program, a federal initiative to help commercialize newer nuclear reactor designs 1.
  • The money backs a four-unit Xe-100 reactor plant planned for Dow’s Seadrift Operations site in Texas. The project sits within the same program and would be the first grid-scale advanced nuclear reactor serving an industrial site in North America 1.
  • X-energy’s wholly owned subsidiary, TRISO-X, LLC, received a license from the Nuclear Regulatory Commission, the main U.S. nuclear regulator, on Feb. 13, 2026, for its fuel fabrication facility project in Oak Ridge, Tennessee 2. That puts X-energy among the few Small Modular Reactor (SMR) developers planning to supply their own fuel, which investors often view as a de-risking factor 3.

This IPO tests a new funding model for powering the AI boom

  • The public offering will test whether capital markets can bankroll the scale of energy buildout tied to AI and data centers 1.
  • Amazon holds equity and may buy power, a pairing that can lower risk for expensive energy projects that lack traditional utility backing 4.
  • If the IPO goes well, it could speed up a shift where tech giants fund new energy producers to lock in carbon-free power, which could unsettle the conventional utility model 5.
  • Other data center operators, including Google, Oracle, and Equinix, have backed SMR technology in recent years 6.
