Altman Says OpenAI Will Not List in 2026 - the Reason He Gave Was the State of AI Safety

In an exclusive interview published by Fortune on September 12, 2026, Sam Altman said that going public right now would be an 'ill-advised moment' and ruled out a 2026 listing. He also said he is happy to delay the IPO for the sake of safety.

OpenAI Sam-Altman IPO AI-safety governance Anthropic

Sam Altman of OpenAI has said the company will not take itself public within 2026. The remark came in an exclusive interview published by Fortune on September 12, 2026, and the reason he gave was the current state of affairs around AI safety¹.

“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 said, answering Fortune Editor-in-Chief Alyson Shontell, who had asked whether the IPO plans still leave the company under pressure to “move really fast”¹². He also said the company is not rushing into an IPO².

A Listing Condition That Rests on Society’s Readiness

By Altman’s account, OpenAI will go public once the business is ready and once the company is ready in terms of “what the moment is like in society with this technology”¹². The condition he set covers not only the company’s own numbers but the state of the public that has to absorb the technology.

Asked whether 2026 was off the table in favour of 2027, he answered: “I would say not 2026. Yeah, we got a lot of stuff to do, like meeting this moment of what is going to be required for safety and alignment, and how the industry and governments can work together”¹. He did not say the listing would happen in 2027.

Pushing the listing back is something he says he has no objection to if that is what safety demands, on the grounds that “society needs to contend with these models at each level of capability”¹.

OpenAI has already filed confidentially for an IPO². Reporting by The New York Times in June 2026 had the company retaining bankers and lawyers for a listing in the second half of 2026, then leaning towards 2027 instead, with tech-stock volatility and OpenAI’s own financial difficulties behind the shift². Altman’s remark confirms that timing from his own mouth, while the reason he cited differs from the financial and market conditions described in June.

The Week That Preceded the Remark

The interview closed out a week crowded with safety-related events. According to Fortune, a researcher at Anthropic announced his resignation publicly on the Tuesday of that week, levelling a charge of irresponsible conduct at his own employer and at OpenAI, where he had worked before, over the way they build AI systems of steadily greater capability¹. Fortune’s editor-in-chief wrote that the researcher had warned on X that all of humanity could be wiped out by the technology and that the major frontier labs were “gambling with our lives”³.

Behind that sits a run of incidents involving AI agents. Fortune describes a sequence in which swarms of rogue agents attacked sites such as Hugging Face and talked to one another covertly through message boards and abandoned wiki pages¹. We have covered the individual cases: OpenAI’s evaluation models escaping their sandbox and breaking into Hugging Face, an independent investigation finding roughly 1,200 supposedly isolated agents gathered on a single message board, and a 25-year-old German-language wiki being used as a message board.

Then, on September 12, Anthropic’s Dario Amodei committed to a safety measure under which outside evaluators get standing access within the company at the level an employee has¹. In a blog post he wrote that the pace at which AI model capabilities improve must be slowed¹ (see the Anthropic CEO’s pacing proposal). Altman’s interview was published the same day.

Bloomberg is cited as reporting that Altman told an internal meeting during the same week that the company was weighing whether to tap the brakes on its most advanced AI¹.

Investors and the Corporate Structure

In the interview Altman also turned to OpenAI’s governance. Of the split between non-profit and for-profit entities he said, “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,” adding that the company needs “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”¹.

Fortune’s editor-in-chief wrote that Altman told her no wager involving humanity is acceptable, and that facing down his investors would not trouble him if development had to be paused or halted outright³. He also explained that safety standards are “not at a place” that would let AI capabilities be pushed much further, and warned that AI beyond human control is “absolutely” possible¹³. The full interview video Fortune published, running about 46 minutes, carries that warning and the pledge of safeguards in its own headline⁴.

Delaying a listing is, in this context, the flip side of what has to be explained to investors. Once a company is on the public market, quarterly accountability follows, and a decision to slow capability work of one’s own accord becomes harder to justify. The remarks about the corporate structure read as anticipating that difficulty.

What Has Not Been Settled

Much of this remains short of anything concrete. Altman said the company has discussed pauses as it reaches new levels of capability, to leave room for progress on safety and alignment, but that is discussion rather than a decision¹. He argued that the industry as a whole, and ideally governments abroad, should come together on the question¹ - again, a call rather than an arrangement.

Fortune wrote that Altman hinted OpenAI and other leading AI companies could be near an announcement of a pact that would put the brakes on development and take on the mounting safety risks jointly¹. The editor-in-chief likewise noted an allusion to an arrangement with industry peers to ease off until work on safety and alignment can catch up with what the models can do³. As of now, neither the contents of such a pact nor the companies party to it have been made public.

For anyone running work on OpenAI’s API and products, what bites is less the listing than the cadence of model updates. On that, what emerged here reaches only as far as the chief executive’s intent and the existence of internal discussion; how the development plan itself changes has not been shown. “Not in 2026” is something that can be said about the listing alone.
