X-energy $XE jumped 27% in its Nasdaq debut on April 24, closing at $29.20 after opening at $30.11. CNBC reported the stock followed an upsized IPO priced at $23 per share, above the marketed $16 to $19 range. That pushed the company through the $1B raise threshold in the skill's Tier-1 IPO filter on day one.

X-energy's IPO announcement said the company sold 44,254,659 Class A shares at $23 and gave underwriters a 30-day option to buy up to 6,638,198 more. The raise totaled roughly $1.02B before any greenshoe exercise. CNBC said it was the largest nuclear public offering on record, a sign that public-market investors are now willing to fund long-duration power infrastructure when the AI build-out creates a clear electricity-demand story.

IPO price: $23 per share vs initial $16 to $19 range
Capital raised: about $1.02B
Debut trading: opened at $30.11, closed at $29.20, up 27%
Order pipeline: more than 11 gigawatts
Amazon deployment target: 5 gigawatts in the U.S. by 2039

The business case is not just ticker momentum. CNBC said X-energy's XE-100 reactor produces 80 megawatts and can be combined into 960-megawatt configurations, while the company is already working with Amazon, Dow and Centrica. It is also developing a 320-megawatt first project with Energy Northwest. That matters because the current nuclear trade is being repriced around deployable capacity and contracted demand, not around distant research milestones.

The next checkpoint is execution. The IPO is expected to close on April 27, and investors will want to see the final SEC prospectus, permitting progress and whether early commercial partners convert the 11-gigawatt pipeline into signed projects and revenue. A 27% first-day pop prices in enthusiasm; the harder part starts with licensing, construction and delivery.
