Shares of X-Energy (NASDAQ: XE) surged 30.9 per cent in their Nasdaq debut, valuing the company at USD$11.9 billion and drawing strong investor demand for carbon-free energy tied to artificial intelligence growth.
The Amazon.com Inc. (NASDAQ: AMZN) backed firm raised USD$1.02 billion by selling 44.3 million shares at USD$23 each. The stock opened at USD$30.11, signaling immediate market enthusiasm. Additionally, the upsized offering reflected stronger-than-expected institutional demand.
The debut gives X-Energy fresh capital as it pushes to deploy its Xe-100 small modular reactors. These reactors aim to deliver reliable, carbon-free electricity by the end of the decade. Furthermore, analysts see SMRs as a key solution for powering energy-hungry AI data centers.
Tech giants and infrastructure developers have shifted toward nuclear energy to secure consistent power supply. Meanwhile, renewable sources like wind and solar still face intermittency challenges that limit reliability. Consequently, nuclear developers have gained renewed attention across capital markets.
Chief executive Clay Sell said the public listing strengthens the company’s financial position and operational flexibility. He explained that access to equity markets allows the firm to scale faster and support its supply chain. In addition, he noted that transparency as a public company improves trust with customers and investors.
Sell also emphasized the importance of building a stronger balance sheet to reduce execution risk. He suggested that scaling reactor deployment requires long-term capital and disciplined investment. Furthermore, he pointed to employee equity incentives as another benefit of going public.

Investor appetite has strengthened further
X-Energy focuses on small modular reactors designed to be cheaper and faster to build than traditional plants. However, large-scale nuclear projects have historically faced delays and budget overruns. Consequently, SMRs have emerged as a more flexible alternative.
The company’s Xe-100 reactor uses helium as a coolant instead of water, which differentiates it from conventional designs. Additionally, X-Energy operates a nuclear fuel business that supplies its own reactors. This creates a recurring revenue stream that appeals to long-term investors.
Founded in 2009, X-Energy has secured customers including Amazon, Dow, and Centrica. Centrica owns a significant portion of the United Kingdom’s nuclear fleet. Meanwhile, these partnerships provide early validation of the company’s commercial strategy.
The company previously planned to go public through a SPAC merger backed by Ares Management in 2023. However, it abandoned those plans due to unfavorable market conditions at the time. Subsequently, improving sentiment in energy and technology sectors reopened the IPO path.
Investor appetite has strengthened further after X-Energy raised two USD$700 million funding rounds since early last year. Those rounds included backing from Amazon, Jane Street, Ares funds and ARK Invest. In addition, repeated capital raises signaled sustained confidence in the company’s long-term outlook.
The broader IPO market has also shown signs of recovery after a slow start to the year. Volatility tied to geopolitical tensions and macroeconomic uncertainty had delayed many listings.
Several high-profile companies, including SpaceX, have filed for potential U.S. listings in recent weeks. This growing pipeline suggests stronger issuance through the remainder of 2026.
The small modular reactor market could reach USD$300 billion to USD$600 billion globally by 2040, according to estimates from the International Energy Agency and industry analysts.
