2026-04-25 companies

New York, Friday, 24 April 2026.
Shares of nuclear developer X-Energy surged 31% in today’s Nasdaq debut, reaching an $11.9 billion valuation as tech companies aggressively seek carbon-free power for artificial intelligence.

A Record-Breaking Market Debut

The Rockville, Maryland-based company, trading under the ticker symbol “XE”, priced its upsized initial public offering (IPO) on April 23, 2026, at $23 per share [2][7]. This entry point sat well above the initially marketed range of $16 to $19 [4][6][7][8]. By offering 44,254,659 shares of Class A common stock, X-Energy successfully raised $1.02 billion [1][2][7][8]. This capital injection officially marks the largest public offering on record for a nuclear energy company [6]. The stock commenced trading on the Nasdaq on the morning of April 24, 2026, with Founder and Chairman Dr. Kam Ghaffarian ringing the opening bell [2][3].

Engineering the Next Generation of Nuclear Power

Founded in 2009, X-Energy differentiates itself from conventional nuclear operators through its proprietary small modular reactor (SMR) technology, designated as the Xe-100 [1]. Unlike all currently operating commercial reactors in the United States, which utilize light water as a coolant, the Xe-100 is a high-temperature gas-cooled reactor that relies on helium [1][6]. Each individual reactor unit is designed to generate 80 megawatts (MW) of power, but the system is engineered to be highly modular; units can be bundled together to create a facility capable of outputting up to 960 MW [6]. Crucially, the high-temperature output is not only suitable for generating electricity but also for providing industrial heat for heavy processes like chemical manufacturing [6].

Navigating the Path to Commercialization

Despite the immense market valuation, X-Energy has yet to begin construction on a commercial reactor [6]. The company aims to deliver its first commercial SMR electrons to the U.S. power grid before the end of the decade, an ambitious timeline that remains subject to rigorous regulatory approvals [alert! ‘nuclear regulatory timelines are historically prone to delays’] [1]. In March 2025, X-Energy and Dow submitted a construction permit application to the U.S. Nuclear Regulatory Commission (NRC) for a proposed project in Seadrift, Texas [6]. The NRC’s initial review process is projected to take 18 months, placing the target completion date for this phase around September 2026 [6]. This review is merely the first part of a two-step regulatory process that will subsequently require an operating license [6].
