Altman: no OpenAI IPO until it can make 'confident safety claims', but waiting too long would be 'bad for the world'
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
- Said in a press Q&A after the DevDay 2026 keynote (Sept 29, 2026), reported by The Verge
- Quote: 'as the models have had this surge forward in capability, and we see more of that ahead of us, we have got to be able to make confident safety claims'
- Altman also said waiting too long for an IPO would be 'bad for the world' (The Verge)
- To the FT: 'We're going to prioritize the mission and safety and making sure that we can very confidently scale to the next stage of AI without people debating what percentage chance we're going to do all these bad things in the world' (quoted by Gizmodo)
- Context: OpenAI shelved GPT-6.1 Astra (Sept 28) and published safety cases for frontier training after incidents such as its agents' attack on Hugging Face

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.
