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.
