Nuclear startup X-energy raised $1 billion in its IPO, selling 44.3 million shares at $23 each — well above its $16–$19 target range and exceeding its initial $800M goal. The Amazon-backed company builds small modular reactors (Xe-100) cooled by helium and fueled by TRISO pellets, capable of generating 80 MW of electricity or industrial heat. X-energy has deals with Dow for a Texas chemical plant and with Amazon for up to 5 GW of nuclear power by 2039. The IPO was driven by surging electricity demand from data centers and broader electrification trends. Shares are set to trade on Nasdaq under the ticker XE.
