Amazon-Backed X-Energy Raises over $1 Billion in IPO
Investor demand pushed the offering above range as Amazon-backed X-Energy plans to use proceeds to expand reactor development and fuel capacity.
On Thursday, nuclear reactor developer X-Energy raised $1.02 billion in its initial public offering, pricing shares at $23 each, a 21% premium above the marketed range of $16 to $19.
Amazon, a key strategic backer, invested about $500 million in 2024 to support X-Energy's SMR technology rollout for its AI-driven data centers. The tech giant also holds a binding commitment to purchase up to 5 gigawatts of nuclear power by 2039.
The Xe-100 reactor uses helium as a coolant flowing over billiard ball-sized pebbles packed with BB-sized TRISO fuel pellets. This pebble bed design allows reactions to slow naturally if the reactor overheats, providing inherent safety without active cooling intervention.
Analyst Vikram Bagri noted the IPO 'suggests continued appetite among investors' for small modular reactors, aligning with recent commitments from Microsoft and Google to secure carbon-free baseload power for their data centers.
Proceeds from the offering will accelerate X-Energy's reactor development and scale up fuel fabrication capacity. The company targets the early 2030s for first commercial deployment of its Xe-100 system.
