OpenAI $1t+ IPO before 2027?

Traders currently price "No" at 81% for "OpenAI $1t+ IPO before 2027?". Over the past 24 hours that probability moved up 0.5 points. The market has traded $296K in total volume and resolves Dec 31, 2026. OpenAI’s confidential IPO filing and internal deliberations have shaped trader sentiment, with recent June 2026 reporting indicating the company is leaning toward a 2027 debut to reach a $1 trillion valuation rather than listing earlier at a lower price. CEO Sam Altman reportedly rejected any valuation haircut below that threshold as a nonstarter, while advisers highlighted risks from broader market conditions and comparable high-profile listings. This uncertainty around achieving the $1T+ milestone before 2027 underpins the strong market-implied odds against an earlier outcome, though a faster timeline remains possible if competitive pressures or revenue growth accelerate plans.
