Market analysis
Analysis generated Sep 5, 2026
Polymarket prices OpenAI's 2026 IPO as a tail risk, with just 1% for September 30 and 9% for December 31. The shift reflects management's August pivot: CFO Sarah Friar told employees the company will debut in 2027, or sooner only if growth accelerates. OpenAI originally targeted Q4 2026 after its June confidential filing, but leadership is now holding out for a $1 trillion-plus valuation rather than accepting the $852 billion private-market price, making 2027 the base case.
