New York, September 12, 2026 — Sam Altman, Chief Executive Officer of OpenAI, has officially ruled out an initial public offering (IPO) for the ChatGPT‑maker during 2026, ending months‑long market speculation over one of the most anticipated listings potentially valued at one trillion US dollars.
In an exclusive interview with Fortune, Altman stated that OpenAI has never faced urgent pressure to go public.
“Given everything unfolding around AI safety, this would be an ill‑advised moment for an IPO,” Altman remarked. He warned that public‑market short‑term earnings cycles could constrain long‑term work on AI alignment, safety research and multi‑stakeholder governance dialogues with governments worldwide.
When pressed whether the listing would shift to 2027, Altman gave a clear reply: “I would say not 2026. We have a great deal of work ahead of us: safety and alignment requirements, industry collaboration and co‑operation frameworks with governments.” He added that the timing of any future IPO will hinge on business readiness and the broader societal context for advanced AI, with no fixed timetable in place.
Back in June 2026, OpenAI confidentially submitted its draft S‑1 filing to the U.S. Securities and Exchange Commission, while stressing that no listing date had been finalised. Earlier reports by The New York Times indicated management was already leaning toward pushing the IPO window beyond 2026, with valuation expectations touching the USD 1‑trillion mark.
Industry observers note multiple drivers behind the decision. Beyond publicly‑cited safety priorities, recent volatility following SpaceX’s market debut and rising alarms over frontier‑AI risks have prompted greater caution within OpenAI’s leadership. Remaining private allows OpenAI to operate free from Wall‑Street quarterly earnings pressure, sustaining heavy investment in safety infrastructure, compute capacity and global policy engagement.
The announcement comes amid a notable shift within the generative‑AI sector. On the same day, Dario Amodei, CEO of Anthropic, called for a more deliberate pace for cutting‑edge model upgrades to mitigate technological risks. Altman voiced agreement with the stance and signalled ongoing talks among leading AI firms over potential industry‑wide voluntary safeguards, a process that would grow more complex under public‑company obligations.
Altman emphasised the postponement does not discard long‑term capital‑market plans. OpenAI will revisit its IPO strategy only when operational maturity, technical safety benchmarks and global regulatory conditions are suitably aligned, keeping its core mission of beneficial AGI at the forefront.
