XE stock is moving more than 11% higher in after-hours trading following news that the Trump administration has selected the nuclear energy company for a $200 million initiative to power AI data centers.

XE shares reached a session high of $18.88 before settling at $18.22.

What Happened

The Trump administration announced a partnership with X-Energy and Oklo, two advanced nuclear reactor developers, to help power AI data centers. This initiative is backed by major tech firms and aims to address the rising energy demands of artificial intelligence infrastructure. X-Energy’s involvement in the program has drawn attention from investors and analysts, with the company’s stock opening with a 0.9% gap up from the prior close. The company’s TRISO-X subsidiary was recently awarded an $11 million economic development grant from Tennessee for its fuel fabrication campus, adding to the positive momentum. Additionally, X-Energy has become a new favorite position for investor Cathie Wood, further supporting the stock’s performance.

What The Data Shows

XE stock is trading within its 52-week range of $16.36 to $37.10. The stock has seen strong intraday movement, with a high of $18.88 and a low of $15.23. Volume so far stands at 4.5 million shares, well above its average. The company’s fundamentals remain challenging, with a net margin of -466.2% and a market cap of $5.3 billion. Despite these figures, the recent news and grant award suggest growing confidence in the company’s long-term prospects.

What To Watch

XE will need to continue demonstrating progress in its nuclear reactor development and securing additional partnerships to sustain investor interest. The broader market reaction to AI infrastructure investments will also be a key factor to monitor.
