How this market resolves

Polymarket's own settlement wording, in full. This, not the headline, decides who gets paid.

Show the full rules

This market will resolve to "Yes" if OpenAI's GPT-7 model is made available to the general public between market creation and the specified date (ET). Otherwise, this market will resolve to "No".

A qualifying model must have a name or model identifier that includes "GPT" and be designated as version 7 or higher, regardless of capitalization or surrounding prefixes, suffixes, dates, or descriptors. Any of OpenAI's general-purpose model families qualifies, including Astra, Sol, Terra, Luna, or a successor general-purpose family, provided the version designation of 7 or higher appears in the name or model identifier. For example, GPT-7, GPT-7 Astra, GPT-7 Sol, or a later version such as GPT-7.1 or GPT-8 would qualify, while models that retain a version designation below 7, such as GPT-6 Astra or GPT-6.1, and models that do not carry an explicit version number of 7 or higher in their name or identifier, regardless of how they are described or positioned, will not qualify. Task-specific or modality lines such as GPT-5.6-Cyber, Daybreak models, Codex, GPT Image, Realtime, transcription, or text-to-speech models will not qualify.

A qualifying model must be launched and publicly accessible, including via open beta or open rolling waitlist signups. A closed beta or any form of private access will not suffice. The release must either be clearly defined and publicly announced by OpenAI as accessible to the general public, or otherwise be made publicly accessible and explicitly labeled on the company's official website. Labeling errors, placeholder text, or version names displayed on the website that do not correspond to a model that is actually accessible to the general public will not qualify.

The primary resolution source for this market will be official information from OpenAI, with additional verification from a consensus of credible reporting.

Scheduled resolution: Dec 31, 2027.
