Polymarket's probability that "GPT-5.6 will open to the public on July 7th" has risen to 64%, a 26% increase in 24 hours.

According to PPP prediction market monitoring tools, the probability of Polymarket's prediction that "GPT-5.6 will be open to the public on July 7th" has risen to 64%, a 26% increase in 24 hours. The rules indicate that GPT-5.6 refers to models explicitly named "GPT-5.6" or those officially recognized as direct successors to GPT-5.5 (such as GPT-5.7, GPT-5.8, etc.), all of which meet the settlement criteria. Task-specific models such as GPT-Codex and Transcribe, cost-optimized versions such as Nano and Mini, and o-series inference models are all included in this market; however, GPT-6 or other next-generation flagship models are not included. Furthermore, eligible models must have been made publicly available, including public beta versions or open waiting lists; closed beta or models limited to private access are not eligible. The final settlement will be based primarily on OpenAI's official announcements and publicly available information on its website, combined with verification through mainstream media reports. On June 27th, OpenAI launched its next-generation GPT-5.6 series models, currently available for limited preview to a select group of partners. Odaily Seer continues to monitor the prediction market, anticipating changes before pricing.
