About OpenAI IPO
OpenAI, the company behind ChatGPT, confidentially filed a draft S-1 registration statement in June 2026, taking a major step toward an initial public offering. A listing would rank among the largest technology IPOs ever, with reporting pointing to a valuation above $1 trillion. This live countdown tracks the time remaining to OpenAI's expected first day of public trading.
The timing is not yet fixed. While some reports floated a debut as early as September 2026, OpenAI's leadership has signaled a preference to wait, and the most cited central estimate points to around the first half of 2027 as the company builds the financial reporting and scale that public markets require. Because the schedule is unofficial, the date here is an estimate and is revised as filings and reporting develop.
An IPO date usually becomes concrete only when a company files an updated prospectus with a price range, typically a couple of weeks before trading begins. Until OpenAI sets that date, this countdown reflects the best current estimate. You can pin this countdown to your own page on countdownit, or spin up a custom countdown for any date with the free countdown maker.
