OpenAI IPO by...?

Traders currently price "December 31, 2026" at 19% for "OpenAI IPO by...?". Full distribution: December 31, 2026 19%, September 30, 2026 4%, August 31, 2026 1%, July 31, 2026 0%. The market has traded $2.7M in total volume and resolves Dec 31, 2026. OpenAI’s recent confidential S-1 filing with the SEC on June 8 marks the clearest near-term catalyst, shifting trader focus toward a potential listing window in late 2026 or early 2027 at valuations nearing $1 trillion. The company has engaged Goldman Sachs and Morgan Stanley while preparing retail share allocations, yet executives emphasize that no firm timeline exists and certain initiatives remain easier privately. Competitive pressure from Anthropic’s parallel filing and broader AI-sector momentum add urgency, though historical patterns show tech IPOs frequently slip due to market conditions or internal priorities. Key upcoming milestones include any public prospectus updates or earnings commentary that could clarify September versus year-end targets.
