Sam Altman just told the world's richest IPO to wait — and the reason is his own product
OpenAI could have gone public in 2026 in what was described as a potentially trillion-dollar listing. Altman says now would be an "ill-advised moment" — because of safety.
A company that many expected to stage the biggest stock market debut in history has decided to sit 2026 out. Sam Altman, the CEO of OpenAI, told Fortune in an interview published on Saturday that going public right now would be "an ill-advised moment", and he named the reason plainly: safety. Not market conditions. Not valuation. The thing his own company builds.
The New York Times reported in June that OpenAI was weighing whether to hold off on a potentially trillion-dollar IPO until next year. Asked directly by Fortune whether 2026 was off the table, Altman said: "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."
Strip away the finance words and here is what happened. An IPO is the moment a private company sells shares to anyone with a brokerage app — the founders and early backers finally turn paper into cash. For OpenAI that moment was described as potentially trillion-dollar. Altman looked at it and said: not this year, and added that the company doesn't "feel pressure on that". Companies delay listings all the time when markets look bad. Almost nobody delays one by pointing at their own product as the risk.
And this is where it gets strange. Altman also suggested to Fortune that OpenAI and other leading AI companies may be close to announcing an agreement to slow AI development and work together on safety risks. On the same Saturday, Anthropic's CEO Dario Amodei published an essay saying "We must slow the pace at which we improve the capabilities of AI models." Altman replied on X: "I agree with Dario that we need to pace the frontier. This has been a primary topic of discussions we've had at OpenAI in recent weeks."
Two rivals, one weekend, the same word: slow.
There is a crack in the story, and it's worth seeing clearly. Safety concerns have not slowed Anthropic's own IPO plans. People familiar with the matter told Reuters this month that Anthropic is expected to begin marketing its offering in mid-October at the earliest and complete the listing days before the US midterm elections in November. So one company is saying slow down while going to market, and the other is saying slow down while staying home. We don't know why the two chose differently — neither of them says.
Anyone who works next to this technology rather than in it: the 20-somethings deciding right now whether to learn a craft an AI model may swallow in two years, and the people already using these tools daily at work and wondering who decides how fast they get more powerful. It also touches anyone with a few thousand in a trading app who half-expected an OpenAI ticker to appear and a chance to buy in early — that chance has moved, and the reason given is not money. And it touches everyone who has watched the same two men be the loudest voices for going faster, and is now reading them both use the word "slow" on the same Saturday.
Two things the source actually names. First: Altman hinted that OpenAI and other leading AI companies may be close to announcing an agreement to slow AI development and cooperate on safety. Watch for whether that agreement is ever announced, and who signs it. Second: Anthropic is expected to begin marketing its IPO in mid-October at the earliest and to complete the listing days before the November US midterm elections, according to people familiar with the matter cited by Reuters. Whether a company preaching restraint lists on schedule is a very public test. Altman said "not 2026" — he did not commit to 2027 either.
Two researchers at Anthropic warned that rapidly progressing AI could lead to the extinction of the human race in the not-too-distant future. That warning did not stop Anthropic's listing plans. It did stop OpenAI's. Read that sentence twice and decide for yourself which company you believe.
