March 20 (Reuters) – X-Energy has filed for an initial public offering in the United States, it said on Friday, as the reactor developer aims ​to tap growing investor enthusiasm for nuclear ‌power.

The U.S. nuclear industry is in midst of a renaissance after years of stagnation, driven primarily by surging power demand from the computing infrastructure required for artificial intelligence systems and President Donald ‌Trump’s ​hopes to quadruple nuclear energy output ⁠by 2050.

X-Energy plans to ⁠list its Class A common stock on the Nasdaq under the ticker symbol “XE”. However, it did not disclose the number of shares to be offered ​and the price range.

The company is developing more than 11 gigawatts of new nuclear capacity through commercial ⁠partnerships in the U.S. and ⁠the United Kingdom. It also plans to ​develop several new reactors designed to run on a more ​enriched type of uranium known as HALEU, though ‌they have not received regulatory licenses.

The nuclear reactor developer is one of the several companies that have signed supply deals with big tech companies and utilities.

Earlier this ⁠week, X-Energy said it would deploy its small modular reactors in Pennsylvania and across the PJM power market along with ⁠independent power provider ‌Talen Energy.

In 2025, the company raised $700 ⁠million to help finish reactor design and ​licensing ‌in a funding round led by Amazon ​and another $700 ⁠million in a round led by trading company Jane Street.

J.P.Morgan, Morgan Stanley, Jefferies, Moelis & Co, Cantor Fitzgerald, Guggenheim Securities, Nomura Securities, and TD Securities are among the underwriters to the IPO.
