X-Energy's stock soared 5.39% intraday on Friday, extending its post-IPO rally momentum as investor enthusiasm for the nuclear energy company continues to build.

The surge is underpinned by significant backing from tech giant Amazon, which invested approximately $500 million in X-Energy and holds a 29% stake in pre-IPO Class A shares. Additionally, ARK Invest's Cathie Wood committed approximately $100 million at the IPO, highlighting strong institutional interest. The company's flagship Xe-100 small modular reactor, which uses helium as a coolant, is specifically targeted to supply power for AI data centers and industrial facilities, tapping into the growing narrative around AI infrastructure power demand.

X-Energy has secured key partnerships with Dow Chemical, Amazon, and UK-based Centrica, with plans to deploy over 5 GWe of Xe-100 reactors across the US by 2039. The company aims for first reactor delivery in the early 2030s, positioning itself at the intersection of the clean energy transition and the AI infrastructure buildout, which continues to attract investor capital.
