This market will resolve to "Yes" if OpenAI completes an Initial Public Offering (IPO) by the listed date ET, as confirmed by official company announcements and credible news sources. Otherwise, this market will resolve to "No". The IPO refers to the first sale of stock by the listed company to the public on any recognized stock exchange. If OpenAI is acquired by another company that is already public, this market will immediately resolve to "No." The resolution source for this market is a consensus of credible reporting.Sam Altman’s September 12, 2026, Fortune interview stating that an OpenAI IPO this year would be “ill-advised” due to the need for substantial artificial intelligence safety and alignment work has become the dominant factor shaping trader sentiment. The company confidentially filed its S-1 in June targeting up to a $1 trillion valuation, yet executives including CFO Sarah Friar have repeatedly pointed to 2027 after observing SpaceX’s post-IPO volatility and broader market caution around high-growth AI listings. Ongoing regulatory scrutiny of large language models, competitive filings from Anthropic, and internal priorities around model capabilities and governance continue to weigh against a near-term debut, though a business inflection or regulatory clarity could reopen an earlier window.
