X-energy closed a $1 billion initial public offering, selling 44.3 million shares at $23 each, a premium over the $16-$19 range it sought. The deal positions the company to accelerate deployment of its small modular reactors for industrial heat and data-center power. The IPO comes as demand for clean, reliable electricity from data centers and electrified industrial processes surges. Nuclear startups like X-energy have gained traction as the sector looks for alternatives to fossil-fuel-based heat. The offering raised $1 billion, exceeding the $800 million the company initially targeted. X-energy will list on Nasdaq under ticker XE. Each Xe-100 reactor delivers 80 MW of electricity and is cooled by helium gas flowing over pebble-sized TRISO fuel pellets, a design that can withstand higher temperatures and reduce meltdowns. Dow has secured a heat-and-power contract with X-energy for a Texas chemical plant, and Amazon has a 5-GW supply agreement led by its Climate Pledge Fund, which also led X-energy's Series C-1 round. The company's reactors aim to provide steady, low-carbon power to data centers and industrial sites.
