TL;DROpenAI filed confidentially for an IPO with Goldman Sachs and Morgan Stanley, potentially listing this autumn. Anthropic filed last week at $965bn. SpaceX lists Thursday at $1.8tn. The AI public market is about to absorb three mega-listings.

OpenAI submitted confidential IPO paperwork to the SEC on Monday, the company confirmed. Goldman Sachs and Morgan Stanley are advising on a potential listing that could come as soon as the autumn, according to people familiar with the matter.

The filing makes OpenAI the third major AI-adjacent company to move towards public markets in a single week. Anthropic filed confidentially last week at a $965 billion private valuation. SpaceX, which now includes xAI, is expected to begin trading on Thursday at roughly $1.8 trillion.

OpenAI’s hedged language

“We have not decided on timing yet; it may be a while because there are things we want to do that are likely easier as a private company,” OpenAI said in a statement. “But it’s a complicated set of tradeoffs and this gives us the option to go public sooner if that ends up being best.”
