OpenAI Readies Confidential IPO Filing at $850B Valuation

OpenAI is set to confidentially file its draft IPO prospectus as early as Friday, working with Goldman Sachs and Morgan Stanley on what could become one of the largest public offerings ever. Private investors currently value the company above $850 billion, and CFO Sarah Friar has framed the move as standard discipline for a company at OpenAI’s scale, with a possible Q4 debut. The filing lands alongside SpaceX’s own imminent prospectus disclosure, setting up a parallel Wall Street showdown between Sam Altman and Elon Musk after their recent federal court clash in Oakland ended in Musk’s loss on timeliness grounds.

The IPO push comes with real pressure beneath the headline numbers. OpenAI has pulled in more than $180 billion from investors and continues to burn cash at a historic clip, and Altman now has to demonstrate a credible path to profitability under public-market scrutiny. Competition is tightening fast: Anthropic is reportedly raising at a $900 billion valuation on the back of $30 billion in annualized revenue, and is pulling ahead in enterprise and AI coding workloads — the segments where margins and stickiness actually live.

For the broader tech and AI landscape, an OpenAI listing would force unprecedented financial transparency onto a company that has defined the generative AI era largely behind closed doors. Disclosed unit economics, compute costs, and customer concentration could reshape investor expectations for the entire frontier-model sector.
