X-energy’s $1B Nuclear IPO Tests Public-Market Appetite (April 25, 2026)

A billion-dollar nuclear IPO is hitting the market, and X-energy is about to learn whether Wall Street’s clean-power appetite includes atoms.

This is Public Co's. Today: X-energy’s upsized debut, the valuation it pulled in, and why nuclear is suddenly trading like a public-market growth story.

Atoms meet appetite.

Exactly. Let’s start with the actual pricing.

From Businesswire:

X-energy, Inc. (“X-energy”), a leader in advanced nuclear reactor and fuel technology, today announced the pricing of its upsized initial public offering (“IPO”) of 44,254,659 shares of its Class A common stock at a public offering price of $23.00 per share. In connection with the offering, X-energy has granted the underwriters a 30-day option to purchase up to an additional 6,638,198 shares of Class A common stock.

That’s a billion-dollar bet on advanced nuclear, right out of the gate. The sales pitch is pretty direct: if AI and electrification keep pushing power demand up, nuclear startups want investors to stop seeing them as science projects.

Then Reuters put numbers on the market reaction. From Pritam Biswas and David French:

X-Energy shares surged 30.9% in their Nasdaq debut, fetching the company a valuation of $11.9 billion and signaling strong interest in the developers of carbon-free energy that has the potential to fuel the unprecedented boom in artificial intelligence.

That’s the market saying AI is also a power story now. Not just chips, not just data centers — electricity. And investors are looking for something that can run all day, in a way wind and solar still can’t always promise.

And before the pricing, Qoo Media had the roadshow details:

X-energy has started the roadshow for its initial public offering as the company moves toward a public listing on Nasdaq. The advanced nuclear reactor and fuel technology developer plans to offer 42,857,143 shares of Class A common stock, with underwriters expected to receive a 30-day option to buy up to 6,428,571 additional shares.

Nuclear is getting the growth-stock treatment very quickly here. The hard part is figuring out whether investors are buying a power revolution — or a promise that takes years, and a lot of money, to prove out.

The Nation Times Team framed just how far above the original target this landed:

Primarily based in Rockville, Maryland, X-energy raised $1.02 billion by promoting 44.3 million Class A shares at $23 every. This value is 21% increased than the highest of its marketed vary of $16 to $19, and effectively above its authentic $800 million goal. J.P. Morgan, Morgan Stanley, Jefferies, and Moelis & Firm led the providing.

A billion-dollar nuclear IPO is not a quiet signal. Investors want power that can run around the clock, not only when the weather cooperates. Now X-energy has to show modular reactors can move from pitch deck to deployed steel.
