OpenAI’s delayed IPO timeline to 2027, following CEO Sam Altman’s September 2026 statement that a 2026 listing would be “ill-advised” amid AI safety priorities, underpins current Polymarket pricing on the eventual ticker. With only a confidential S-1 filed in June and no public registration or banker announcements on symbol selection, traders assign the highest implied probability (43.5%) to $OAI for its direct, intuitive linkage to the company name. Shorter alternatives like $OA (30.4%) and $CGPT (29.6%) trail as secondary options reflecting common conventions for memorable equity symbols, while lower-priced choices capture residual speculation. Recent private funding discussions targeting $1.2–1.4 trillion valuations and Anthropic’s potential November debut provide indirect context on market conditions but have not shifted ticker-specific sentiment.
