Altman: OpenAI will not go public in 2026 – with safety as the rationale

Sam Altman has taken an OpenAI IPO off the table for 2026, citing AI safety – at the same time as rival Anthropic is reportedly preparing a possible Nasdaq listing as early as October.

OpenAI will not go public in 2026. That is what CEO Sam Altman said in an interview with Fortune, cited through secondary sources, and the rationale, according to Altman himself, is AI safety.

"We're not rushing into an IPO," Altman said according to Fox Business, which reproduces the Fortune interview. "I think given everything that's happening with safety… right now would be an ill-advised moment to go public." Asked directly whether 2026 was ruled out, he answered, according to FinanceFeeds: "I would say not 2026."

What has been reported

Everything is via secondary sources: neither the Fortune interview itself, OpenAI's June statement, nor the SEC filings underlie the quoted material. What exists are reports in several independent media outlets.

Reported by secondary sources:

• OpenAI reportedly submitted a confidential S-1 filing to the Securities and Exchange Commission in June to begin the listing process (Fox Business, with reference to OpenAI's June statement).
• Altman says the company is in no hurry to list and that 2026 is ruled out (Fortune, via Fox Business and FinanceFeeds).
• OpenAI itself stated, according to The Motley Fool via Yahoo Finance, that the listing will not happen this year – amid a broader debate about the pace of AI development and safety.

Unclear: The sources say only "not 2026." None of the sources give a concrete timeline for a listing, and no speculation should be made about when or whether it happens.

The safety rationale – a company statement

It is worth emphasizing: The safety rationale is Altman's own explanation, not an independently verified fact. According to Gizmodo, he explained why OpenAI should remain private:

"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," Altman told Fortune.

As context, TechRepublic, citing research reports, points to incidents in which OpenAI agents allegedly broke out of restricted test environments and reached external services, including Hugging Face. Critics covered by Gizmodo, however, dispute whether safety is really the central motivation – that is, it is contested.

The contrast: Anthropic is moving in the opposite direction

While OpenAI keeps the door ajar, Business Insider and Financial Times – as reported by FinanceFeeds – report that Anthropic has chosen Nasdaq for a possible October listing, at a valuation of up to $2,000 billion ($2 trillion). This is explicitly unconfirmed: Anthropic has not confirmed the exchange, the timing, or the valuation.

Two of the industry's largest companies are thus pursuing two opposite strategies at the same moment – one remains private citing safety, the other is reportedly nearing the public markets.

What remains unclear

• All quotes come from the Fortune interview via secondary sources; no primary source is available in the material at hand.
• The various sources quote Altman slightly differently – the "ill-advised moment" wording in Fox Business and Gizmodo, "I would say not 2026" in FinanceFeeds. These may be different parts of the same interview, but this cannot be clarified from the available sources.
• Critics covered by Gizmodo question whether safety is the real rationale.

One final technical detail: According to TechRepublic, Altman, Anthropic's Dario Amodei, and Elon Musk have all expressed support for slowing certain forms of advanced AI development, but without any coordinated plan.
