CONFIDENTIAL-S1 filed
Confidential registration lead
Reuters reported on May 20 that OpenAI was preparing to file confidentially and was targeting an IPO as early as September 2026. OpenAI then said on June 8 that it had recently submitted a confidential draft S-1 to the SEC. In that same disclosure, the company said it had not decided on timing and that a listing may still be a while away, so the September window remains reported press timing rather than company guidance.
