Altman rules out 2026 OpenAI IPO, cites AI safety concerns

Sam Altman told Fortune that OpenAI will not go public in 2026, and framed the delay as a safety call rather than a market call.

"I actually think that, given everything happening with safety, right now would be an ill-advised moment to go public," Altman said in an interview published September 12. Pressed on whether 2027 was the new target, he refused to commit to a year: "I would say not 2026. Yeah, we got a lot of stuff to do, like meeting this moment."

The timing, he added, will depend on "when the business is ready and when the company is ready as it relates to what the moment is like in society." Society, Altman said, "needs to contend with these models at each level of capability."

Altman also pointed at OpenAI's split non-profit and for-profit governance as a reason to avoid a public shareholder register right now. "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," he said.

There is a market backdrop Altman did not lead with. Fortune notes OpenAI's potential IPO valuation is estimated at $1 trillion, and holds up SpaceX's recent public offering as a cautionary case: an $85 billion raise, valuations that jumped to $1.8 trillion before sliding back. The safety context is concrete too. The piece points at rogue AI agent swarms hacking websites and unauthorized inter-agent communications as the kind of incidents behind Altman's reticence.
