Sam Altman: OpenAI Won't Go Public in 2026, Calls IPO 'Ill-Advised'

OpenAI CEO Sam Altman just took the year's most-anticipated IPO off the table. In a new Fortune interview, he said going public right now would be a mistake given where AI safety stands.

What Altman actually said

Altman confirmed the offering will not happen in 2026, pushing back on Wall Street's timeline for one of the largest expected listings in history.

“I actually think that, given everything happening with safety, right now would be an ill-advised moment to go public, and we don’t feel pressure on that,” Altman told Fortune Editor-in-Chief Alyson Shontell. He added that OpenAI will list when the business and society are ready for it.

Why the delay matters

The decision pushes one of the most anticipated IPOs in history until at least 2027 and gives the clearest sign yet that mounting concerns about increasingly powerful AI are beginning to reshape the industry's business plans.

OpenAI CFO Sara Friar told employees just last month that the company would likely go public in 2027 or even sooner, if the business continued to inflect. Altman's comments effectively harden that later timeline.

The broader AI mood shift

Altman's comments came on the same day that Anthropic CEO Dario Amodei published an essay urging AI companies to slow how quickly they improve their most advanced models.

Both Altman and Elon Musk quickly agreed with Amodei's call for a slowdown in the AI race. That is a notable tonal shift from an industry that has been in all-out capex mode.

Governance still complicated

“We have put up with this incredibly complicated structure for a long time, and this moment that we’re in now is kind of why,” Altman said, alluding to its corporate governance that’s split between non-profit and for-profit entities. “We need to be able to make decisions that are not obviously in the interest of our business and our shareholders for the responsibility of fulfilling our mission and what that’s going to require.”

Translation for traders: public-market discipline is not something Altman wants imposed on OpenAI right now.

Options market and stocks to watch

Watch for continued sensitivity in the AI complex as the IPO calendar thins out:

• MSFT — OpenAI's largest backer. A delayed IPO keeps the value of Microsoft's stake locked in private markets longer; watch for reaction in AI-linked flow.
• NVDA — Any hint of an industry-wide slowdown in AI capex is a headline risk for Nvidia. Watch for changes in short-dated skew.
• GOOGL — A longer runway before OpenAI is publicly scrutinized could be a relative positive for Google's own AI narrative.
• META — Another hyperscaler whose AI spend narrative is tied to peer sentiment on the pace of development.
• CRWV — CoreWeave and other AI-infrastructure names remain highly correlated to OpenAI headlines. Watch flow around any follow-through in the Amodei/Altman safety debate.
