PPP Prediction Market Tool monitoring shows that the probability of "GPT-5.6 opening to the public on July 7" on Polymarket has risen to 64%, up 26% in 24 hours.
The rules state that models explicitly named "GPT-5.6" or officially recognized as direct successors to GPT-5.5 (such as GPT-5.7, GPT-5.8, etc.) qualify for settlement. Task-specific models such as GPT-Codex and Transcribe, cost-optimized versions like Nano and Mini, and the o-series inference models are included in this market; however, GPT-6 or other next-generation flagship models are not included.
In addition, eligible models must be publicly available, including public beta versions or open waitlists; closed beta tests or private access only do not qualify. The final determination will be based primarily on official announcements and publicly available information from OpenAI, supplemented by verification through mainstream media reports.
On June 27, OpenAI launched the next-generation GPT-5.6 series models, currently available in a limited preview for select partners.
