Polymarket: Probability of "GPT-5.6 will be publicly released on July 7" rises to 64%, up 26% in 24 hours

PPP prediction market tool monitoring shows that the probability of "GPT-5.6 will be publicly released on July 7" on Polymarket has risen to 64%, up 26% in 24 hours. The rules specify that GPT-5.6 refers to a model explicitly named "GPT-5.6" or a model officially recognized as a direct successor to GPT-5.5 (such as GPT-5.7, GPT-5.8, etc.), all of which meet settlement conditions. Task-specific models like GPT-Codex, Transcribe, cost-optimized versions like Nano, Mini, and reasoning models in the o-series are included in this market; however, GPT-6 or other next-generation flagship models are excluded. Additionally, eligible models must be publicly accessible, including public beta versions or open waitlists. Closed testing or private access only does not meet the requirements. Final settlement will be based on OpenAI's official announcements and publicly available information on its website, supplemented by verification from mainstream media reports. On June 27, news broke that OpenAI launched the next-generation GPT-5.6 series models, currently available for limited preview to select partners.
