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

Source-context snapshot as of 2026-06-16T06:14:58Z:
The market criteria ask for the first official public release or general availability of a model designated GPT-5.6 by OpenAI.
OpenAI's News page currently shows recent Jun 2026 posts such as the Partner Network, Academy courses, Ona acquisition, and Oracle access announcement; I do not see a GPT-5.6 announcement there.
OpenAI's GPT-5.5 launch page is dated Apr 23, 2026, with an Apr 24 update saying GPT-5.5 and GPT-5.5 Pro are available in the API.
OpenAI's model release notes currently show a GPT-5.5 Instant update dated May 28, 2026.
The OpenAI API models index labels the latest model as GPT-5.5 and lists GPT-5.5/GPT-5.5 Pro and GPT-5.4 variants; I do not see GPT-5.6 listed there.
My read: the official-source trail is negative for the May 31 / Jun 7 / Jun 14 buckets, and the Jun 21 / Jun 28 buckets require a fresh official OpenAI naming or GA signal rather than rumors or unrelated model-family updates.
