OpenAI Prepares IPO Filing With Listing Targeted as Early as September

New reporting says OpenAI may confidentially file its IPO prospectus as soon as Friday at a private-market valuation above $850 billion, while launch plans could move into the fourth quarter.

Fact Check
The claim is strongly supported by multiple independent, high-authority sources all published on May 20, 2026. The Wall Street Journal broke the story as an exclusive, reporting OpenAI is preparing a confidential IPO filing with Goldman Sachs and Morgan Stanley, possibly as early as Friday May 22, with a September listing target. CNBC and the Financial Times independently corroborate the filing timeline and September listing window. CryptoBriefing (citing WSJ) adds the specific detail of a valuation above $1 trillion. All sources are consistent and mutually reinforcing. The only minor uncertainty is that the filing had not yet been submitted as of the reporting date (it was described as imminent), and the $1 trillion valuation figure is a target rather than a confirmed figure, but the core claim about IPO filing preparation and September listing timeline is well-established across tier-1 financial news outlets.
Summary

OpenAI is reportedly preparing an initial public offering filing that could be submitted as soon as Friday, with its private-market valuation said to exceed $850 billion. The company is reportedly working with Goldman Sachs and Morgan Stanley on the prospectus, and the IPO could launch as early as the fourth quarter. This update changes the previously reported timing that had pointed to a public listing as early as September and also presents a lower valuation figure than the earlier report that said OpenAI might seek a valuation above $1 trillion.
