Amazon-backed X-Energy continues post-IPO rally
Nuclear energy company X-Energy continued to rise in premarket trading on Monday after rushing out of the gate on its Nasdaq debut.
X-Energy shares closed 27% above their IPO price on Friday, its first day as a publicly-listed company. Shares have risen another ~16% before the bell on Monday.
The company raised $1 billion for its IPO, with high-profile backers including Amazon and Ken Griffin, the founder of the hedge fund Citadel. X-Energy had a market capitalization of $11.6 billion as of Friday’s close.
The company uses modular nuclear reactors to produce energy for industrial facilities and data centers, joining a list of energy startups including Oklo and Fermi looking to profit from the artificial intelligence boom’s massive energy demand.
X-Energy, which counts Dow, Inc. and Amazon among its clients, reported $109.3 million in revenue in 2025 and a $390 million net loss for the year.
