Traders currently price "$800B" at 87% for "OpenAI IPO closing market cap above ___ ?". Full distribution: $800B 87%, $1T 73%, $1.2T 59%, $1.4T 41%. The market has traded $1.5M in total volume and resolves Dec 31, 2027. OpenAI’s confidential S-1 filing in May 2026 and ongoing private fundraising at roughly $852 billion underpin elevated expectations for an IPO targeted as early as late 2026. Traders focus on the company’s $2 billion monthly revenue run rate, four-times-faster growth than peers at comparable stages, and enterprise share exceeding 40 percent, which together support market-implied valuations near or above $1 trillion despite projected 2026 losses of around $14 billion. Key swing factors include AI model releases, competitive pressure from Anthropic, and broader tech IPO multiples, with any delay into 2027 or weaker-than-expected profitability trajectory likely pressuring first-day closing market cap.
