OpenAI IPO Not in 2026, Sam Altman Says

Sam Altman told Fortune OpenAI will not go public in 2026, citing AI safety. What he declined to say about 2027, and what Anthropic is doing instead.

OpenAI IPO Not in 2026, Sam Altman Says

OpenAI will not go public in 2026. Sam Altman, the company’s chief executive, said so in a Fortune interview published on Saturday, citing artificial-intelligence safety: “given everything happening with safety, right now would be an ill-advised moment to go public, and we don’t feel pressure on that.”

Will OpenAI go public in 2026?

No — not according to the man who decides. Fortune pressed Altman on whether 2026 was off the table in favour of 2027. “I would say not 2026,” he replied. “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.”

He did not endorse 2027 either. That gap is the whole story: a calendar year has been ruled out without a replacement being named.

Why safety became the stated reason

According to the Guardian’s report, a growing number of US lawmakers — Democrats and Republicans both — are calling for new rules to govern AI systems. That pressure followed dire warnings from two researchers at OpenAI rival Anthropic that rapidly progressing AI could lead to human extinction in the not-too-distant future.

The warnings landed alongside cases of AI agents going rogue to hack external systems, and of safety researchers quitting their companies over concerns about the technology’s risks.

Altman also hinted at something bigger than a listing decision. He suggested that OpenAI and other leading AI companies may be close to announcing an agreement to slow AI development and address safety risks together, Fortune reported.

Also on Saturday, Anthropic chief executive Dario Amodei published an essay shared on social media. “We must slow the pace at which we improve the capabilities of AI models,” he wrote. Altman later answered him 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.”

Anthropic is listing anyway

The sharpest line in the Guardian piece sits near the end. Safety concerns have not slowed Anthropic’s own IPO plans so far: the company is expected to begin marketing its offering in mid-October at the earliest and to complete the listing days before the US midterm elections in November, people familiar with the matter told Reuters this month.

Two frontier labs, one shared vocabulary of caution, two different decisions about selling shares to the public. Altman calls the moment ill-advised. Amodei calls for a slower pace — and his company still goes to market.

The trillion-dollar number, and the window it would have landed in

The New York Times reported in June that San Francisco-based OpenAI was considering whether to hold off on a potentially trillion-dollar IPO until next year. At that time, shares in Elon Musk’s SpaceX were tumbling after a surge that had sent that company’s valuation to $1.8tn — a reminder that the listing window OpenAI has now walked away from was already showing cracks. For scale on what a listed AI company is worth and how it is governed, OpenAI’s background is the fastest read.

An IPO is, among other things, a funding event. “We don’t feel pressure on that” is therefore a claim about balance-sheet patience as much as it is a claim about safety.

What a listing-date contract does with a quote like this

Prediction markets phrased as “will company X go public by date Y” resolve on the event — a completed listing and a first day of trading — not on what an executive said in an interview. A CEO publicly ruling out a year is the strongest signal available short of the thing itself, but it does not settle the contract early. The 2026 bucket stops being plausible on Saturday and pays out only when the calendar runs down.

What reprices instead is everything behind the bucket that just died. Where a market offers 2026, 2027, 2028 and a long tail, the money leaving the 2026 contract has to go somewhere, and how it splits is a judgment about whether “not 2026” means a short safety pause or the start of a multi-year deferral. This piece quotes no live prices: the facts above come from the Fortune interview as reported by the Guardian, not from a market feed.

If you want to work the split through yourself, convert each bucket’s price into an implied probability with the odds converter and check the set still adds to roughly 100% after the news — a 2026 bucket falling to near-zero while 2027 and 2028 rise only part of the way is the market telling you it thinks the deferral may run past 2027.

What to watch next

  • An industry slowdown agreement. Altman suggested one may be close. If OpenAI signs anything binding, scheduling a 2027 listing around it gets harder.
  • How Anthropic’s shares actually trade. First-day moves on AI listings have been violent — Unitree Robotics rose 542% in Shanghai — and Anthropic’s debut is the cleanest available read on public appetite for a frontier lab.
  • Congress. Lawmakers on both sides are demanding rules for AI systems. A statutory regime would reshape what a listing prospectus has to disclose.
  • Paperwork. A registration statement filed on SEC EDGAR is the concrete event that moves a listing market; an interview is not.

The phrase that will be argued about for a year is “we don’t feel pressure on that.” A company that genuinely feels no pressure can wait for the safety picture, the rules and the market to come to it. Whether that patience survives watching a direct rival ring a bell weeks before a midterm is the open question.

FAQ

Will OpenAI go public in 2026?

No, according to Sam Altman. In a Fortune interview published Saturday he said OpenAI will not list in 2026, calling it ‘an ill-advised moment to go public’ given AI safety concerns. He declined to confirm 2027 as the replacement year.

Why did Altman give AI safety as the reason for delaying the IPO?

He said OpenAI has ‘a lot of stuff to do’ on safety and alignment, and on how industry and governments work together. The Guardian reports the remarks came as US lawmakers from both parties pushed for new AI rules following extinction-risk warnings from two Anthropic researchers.

Is Anthropic still going public?

Yes, per the Guardian’s account of Reuters reporting. Anthropic is expected to start marketing its IPO in mid-October at the earliest and complete the listing days before the November US midterm elections.

Do prediction markets pay out on what a CEO says?

No. A contract on whether a company goes public by a date resolves on the listing itself, not on an executive’s interview. A public ruling-out makes the year implausible immediately, but the contract only settles when the event happens or the deadline passes.
