X-energy, the Amazon-backed small modular reactor developer, has filed for an initial public offering (IPO), marking a significant entry into the nuclear energy market. The company submitted a draft registration statement to the Securities and Exchange Commission on Friday, positioning it for a potential listing in the early summer. This move comes amid surging investor interest in SMRs as a solution to growing electricity demand driven by data centers and electrification trends. BloombergNEF data projects U.S. data center power demand to rise from 34.7 gigawatts in 2024 to 106GW by 2035, underscoring the scale of infrastructure needs that SMRs could address.

X-energy's helium-cooled reactor design addresses a critical supply chain vulnerability: helium shortages caused by disruptions in the Strait of Hormuz have spiked commercial prices by 50-200% according to Fitch analysts. The company secured $400mn from Amazon and Citadel's Ken Griffin in October 2024, followed by a $700mn round led by Jane Street and ARK Invest in November. It has already secured contracts with FTSE 100-listed Centrica and Dow, demonstrating market validation despite not yet receiving full Nuclear Regulatory Commission approval for reactor deployment. The IPO would make it the fourth publicly traded SMR company, joining Nano Nuclear, NuScale Energy, and Sam Altman-backed Oklo.

While X-energy's stock could benefit from the SMR sector's momentum—Oklo's shares gained 94% last year—the company faces headwinds including helium price volatility and regulatory hurdles. The filing arrives as Wall Street prepares for a wave of tech IPOs, though geopolitical risks could impact the market. X-energy's pricing and fundraising target remain undisclosed, with JPMorgan, Morgan Stanley, and Jefferies handling the bookrunning duties.
