Amazon-Backed X-Energy Raises $1.02 Billion in Upsized IPO to Fuel Nuclear Reactor Push
Rockville, Maryland – April 24, 2026 — X-Energy Inc. and its underwriting syndicate announced the completion of a $1.02 billion initial public offering, pricing 44.3 million Class A shares at $23 each and surpassing the marketed range of $16-$19. The Amazon.com Inc.-backed nuclear developer achieved a $9.1 billion valuation, with proceeds earmarked for advancing its Xe-100 small modular reactor technology and scaling TRISO fuel production to meet AI-driven power demand. Trading commenced Friday on Nasdaq under ticker “XE.”
Announcement Specifics
X-Energy sold 44.3 million shares through lead underwriters JPMorgan Chase & Co., Morgan Stanley, Jefferies Financial Group Inc., and Moelis & Co. The Rockville-based company reported a net loss of $390 million on $94 million revenue (excluding grants) last year. IPO proceeds will fund reactor development, TRISO fuel fabrication expansion at its Oak Ridge, Tennessee facility, and commercialization efforts targeting first deliveries in the early 2030s.
Stakeholder Perspectives
“suggests continued appetite among investors for small modular reactors.”
— Vikram Bagri, Analyst at Citigroup
Why it matters: The statement underscores market confidence in advanced nuclear technology as a viable solution for carbon-free baseload power amid accelerating energy consumption from data centers and industrial facilities.
“game changer”
— Clay Sell, CEO at X-Energy (referring to Amazon’s commitment)
Why it matters: Amazon’s $500 million 2024 investment and 5 GW deployment commitment through 2039 provide the financial anchor and offtake certainty required to commercialize the Xe-100 platform at scale.
Industry Context
X-Energy’s Xe-100 is a helium-cooled, graphite-moderated pebble-bed small modular reactor utilizing TRISO fuel, designed for applications in power generation, industrial heat, hydrogen production, and desalination. Amazon’s portfolio includes a 320 MW project with Energy Northwest in Washington state, while partnerships with Dow for a Texas demonstration facility and Centrica contribute to an 11 GW development pipeline. Hyperscalers are accelerating nuclear investments as traditional renewables struggle to deliver the 24/7 carbon-free baseload required for AI data center operations.
The company previously attempted a 2023 SPAC merger with an Ares Management-backed entity, which was abandoned due to unfavorable market conditions.
Conclusion
X-Energy’s oversubscribed IPO demonstrates institutional confidence in advanced nuclear as a critical infrastructure layer for U.S. industrial and technology growth. The company will focus on regulatory approvals and fabrication scale-up, positioning the Xe-100 for commercial operation in the early 2030s as demand for reliable, carbon-free power intensifies.
