X-Energy’s Leap: From Failed SPAC to Record-Breaking IPO

Published on April 24, 2026

X-Energy was poised for a massive breakthrough in 2023 with plans for a $1 billion SPAC. However, those plans crumbled, leaving the company in search of new avenues to raise capital.

The IPO became a remarkable success, raising $1.02 billion and marking the largest nuclear IPO in history. Demand was overwhelming, with the offering being oversubscribed by 15 times, and shares surged by 31% upon debut, reflecting a market cap of approximately $12 billion.

This transformation highlights a favorable shift in investor sentiment towards nuclear energy. What was once a cautious approach to SPACs has now turned into enthusiastic backing for companies in traditional public offerings, revealing a keen interest in innovative energy solutions.
