Summary

This market will resolve according to the calendar date (ET) on which OpenAI's GPT-5.6 model is made available to the general public. GPT-5.6 refers to a product explicitly named GPT-5.6, or a variant that is recognized as a direct successor to GPT-5.5, similar to the progression from GPT-5.1 to GPT-5.2. (e.g., GPT-5.7, GPT-5.8, etc., would qualify toward this market) Qualifying releases of task-specialized models (e.g., GPT-Codex/Transcribe), cost-efficiency variants (e.g., Nano/Mini), or reasoning models of the o-series family will count for this market. Products labeled as a new flagship generation GPT-6 or similar 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 be either clearly defined and publicly announced by OpenAI as being accessible to the general public or otherwise made publicly accessible and explicitly labeled within 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.
