Polymarket · x · 2026-11-11

Polymarket's market on an OpenAI IPO before Q3 2027 now prices a 46% chance, right after OpenAI reported its first $10 billion revenue quarter with sales up nearly 200% year-over-year.

Context: President Greg Brockman said the company looks ready after enterprise revenue doubled and now accounts for most sales; CFO Sarah Friar confirmed the 2027 timeline despite data center spending; Sam Altman had ruled out a 2026 listing. OpenAI secretly filed an S-1 in June 2026 and raised a scaled-back $20B private round at $1.25T valuation, ahead of Anthropic's expected November debut.
