OpenAI has confirmed the release of its GPT-5.5 model, fully settling all associated release date markets. The market for a GPT-5.5 release by April 23 now stands at 100% certainty, a significant increase from 84% just a week prior. Other markets for April 30 and June 30 also settled at 100% YES.
Daily trading volume for these prediction markets reached $233,954 in USDC. A minor shift occurred prior to the announcement, with a 3-point drop in the April 23 sub-market, indicating traders were positioning ahead of the news.
With all release date contracts at maximum certainty, further betting on the timing is unsubstantiated. The official announcement has been made, and markets reflect full confidence in the projected timeline.
Attention will now shift to GPT-5.5's benchmark performance against competing AI models and subsequent announcements from OpenAI. Executives like Sam Altman are expected to focus on deployment metrics and user feedback.
