Resolution criteria
This market resolves to the option corresponding to the first official public release or general availability date of the model designated as "GPT-5.6" by OpenAI.
"By May 31st" resolves to YES if the release date is on or before May 31, 2026.
Subsequent options resolve to YES if the release date falls within the respective weekly windows, following the exhaustion of the prior timeframe.
If no model officially named "GPT-5.6" is released by the latest provided date, this market will resolve to N/A.
Resolution will be determined by official announcements from OpenAI’s newsroom (https://openai.com/news/) or verified statements from OpenAI leadership. In the event of a staged rollout, the date the model becomes generally available to the public or via the ChatGPT interface will be considered the release date. I will also consider the resolution of this market in case of ambiguities https://polymarket.com/event/when-will-gpt-5pt6-be-released
