Westinghouse Electric targets over $50B valuation in US IPO

Westinghouse Electric, the company whose reactor technology powers more than half the world’s operating nuclear plants, is preparing to go public at a valuation north of $50 billion. That’s a striking number for a company that changed hands for approximately $8 billion in late 2023.

The company confidentially filed a draft registration statement with the SEC on July 31, 2026, keeping the specifics around share count and pricing under wraps for now.

From $8 billion to $50 billion in under three years

Brookfield Renewable Partners holds a 51% stake in Westinghouse, with Cameco Corp. owning the remaining 49%. The pair completed their acquisition in late 2023 at an enterprise valuation of roughly $8 billion.

Analysts have estimated Westinghouse’s valuation in a range from $26 billion to north of $30 billion, which sits well below the reported IPO ambitions.

Why nuclear, why now

In October 2025, the US government, Brookfield, and Cameco formalized a strategic partnership aimed at deploying new Westinghouse AP1000 reactors. The ambition is enormous: at least $80 billion in deployment contracts for new reactor builds.

That partnership also includes a provision allowing the government to acquire equity in Westinghouse, potentially up to 20%, if certain milestones are hit. One of those milestones involves the company reaching a $30 billion valuation by January 2029.

What public investors are really buying

The core tension in this IPO is the entry price. Brookfield and Cameco acquired Westinghouse at roughly $8 billion. They’re now seeking a public valuation that implies more than six times that figure.

If Washington exercises its option for up to a 20% stake, that dilutes other shareholders.

Westinghouse’s AP1000 reactor at the Vogtle plant in Georgia, completed in recent years, ran years behind schedule and billions over budget.
