Altman: no OpenAI IPO until it can make 'confident safety claims', but waiting too long would be 'bad for the world'

★★★after cutoffbusinessOpenAIconfidence: high

In a Q&A with reporters after his DevDay 2026 keynote on Sept 29, 2026, Sam Altman said OpenAI will not go public until it can make "confident safety claims" about its increasingly capable models. He also said that waiting too long for an IPO would be "bad for the world". He had already ruled out a 2026 IPO on Sept 12. The remarks came the same day Bloomberg reported a $30B+ private bridge round.

Key facts

What happened

After the DevDay 2026 keynote, Altman told reporters that OpenAI will not list its shares until it can credibly vouch for the safety of its models. He said a listing during the move to more capable models, with new safety requirements coming, could push the company to put investors' expectations ahead of safety. He also said that delaying too long would be "bad for the world". He did not give a date. On Sept 12 he had said there would be no IPO in 2026.

Why it matters

The CEO of a leading lab has made the timing of its IPO depend on safety claims. Its main rival, Anthropic, is moving toward a listing with a leaked prospectus. OpenAI is instead raising private bridge capital, reportedly at a ~$1.4T valuation.
