Polymarket’s probability that “GPT-5.6 will open to the public on July 7” rose to 64%, up 26% over the past 24 hours. According to Odaily, the market’s rules define GPT-5.6 as a model explicitly named “GPT-5.6” or a model officially recognized as a direct successor to GPT-5.5, including versions such as GPT-5.7 or GPT-5.8.
The rules state that task-specific models such as GPT-Codex and Transcribe, cost-optimized versions such as Nano and Mini, and the o-series reasoning models are included in the market, while GPT-6 or other next-generation flagship models are excluded.
To qualify, the model must be made available to the public, including through a public beta or an open waitlist. Closed testing or private-only access does not meet the requirement. Settlement will primarily rely on OpenAI’s official announcements and publicly available information on its website, with verification based on mainstream media reports.
Odaily reported that on June 27, OpenAI introduced its next-generation GPT-5.6 series models, which are currently in a limited preview for a small number of partners.
