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.OpenAI CEO Sam Altman confirmed in a mid-September 2026 Fortune interview that the company will not pursue an IPO this year, citing the need to prioritize AI safety, alignment work, and potential regulatory coordination as a private entity. This followed CFO Sarah Friar’s August statement to employees targeting a 2027 listing, or sooner only if business momentum accelerates sharply. The June confidential S-1 filing with Goldman Sachs and Morgan Stanley had initially fueled expectations of a late-2026 debut at up to $1 trillion, but SpaceX’s post-IPO volatility and valuation ambitions shifted internal consensus. OpenAI’s most recent private round valued the company at $852 billion, and it is now weighing another large private funding round. Rival Anthropic’s parallel filing and ongoing AI safety debates remain key variables for traders assessing any 2026 resolution.
