This market asks whether OpenAI will make a product called GPT-5.6 publicly available by July 31, 2026. It is worth watching because the wording is very specific: the release has to be official, public, and close enough to the GPT-5.5 line to count under the market’s rules.
The title is about a concrete launch deadline, not just a rumor of a future model. For a Yes resolution, OpenAI must release a model explicitly named GPT-5.6, or a clearly related successor in that numbering family, and it must be accessible to the general public by the end of July 31, 2026 ET. The rules also say certain related products can count, including task-specialized variants, efficiency versions like Mini or Nano, and o-series reasoning releases, but a new flagship labeled GPT-6 would not.
The uncertainty is about product timing and naming, both of which OpenAI can control but does not always announce far in advance. Readers care because model rollouts often arrive through staggered public access, waitlists, or official website updates, and the market is pricing whether a qualifying release will happen before the deadline. The live market is strongly leaning toward Yes, which suggests traders expect a public launch to arrive on time, but the outcome still depends on the exact wording of any official release.
An official OpenAI announcement naming GPT-5.6, or a public launch page showing a qualifying model that is actually accessible, would push the market toward Yes. By contrast, a delay, a release that stays in closed beta, or a launch under a different name such as GPT-6 would weaken the Yes case under these rules. The price can also move if OpenAI releases a related model that raises a naming question, since the market explicitly allows some successor and variant labels but rejects placeholder text or labels that do not correspond to public access.

View marketThe current market price implies roughly a 95% chance for the leading outcome, based on live Polymarket pricing. That number is not a prediction from PredictionNinja and it is not a guarantee; it is the current crowd-priced view of the market and can change quickly when new information appears.
The main source of truth is OpenAI’s official information, especially the company’s website and any public release notes or product pages. Before the deadline, readers should check whether the model is publicly accessible, not just announced, and whether the name fits the market’s allowed GPT-5.6-family wording. The biggest ambiguity risk is naming: a similar-sounding model, a temporary placeholder, or a private beta would not automatically count, so the exact public label and access status matter most.

This market is currently listed with an end date of Jul 31, 2026. Market timelines can change if the underlying event is postponed, rescheduled, or resolved early.
This market will resolve to "Yes" if OpenAI's GPT-5.6 model is made available to the general public by the specified date (ET). Otherwise, this market will resolve to "No." 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 a "Yes" resolution to 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. For this market to resolve to "Yes," 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.
Probability signal
The current price implies a strong favorite, so new information would need to be meaningful to move the market sharply.
Liquidity context
Liquidity is relatively deep for a prediction market page, so quoted prices may be more reliable than very thin markets.
Spread
The bid-ask spread is wider, so the headline probability may be less precise than it looks.
Recent movement
The 24h move is modest, suggesting the market has not repriced dramatically in the latest feed.
The current displayed probability is 95%, based on the latest normalized Polymarket data available to PredictionNinja.
The rules and resolution criteria are pulled from the market description provided by Polymarket when available.
Prediction markets can move whenever traders react to new information, liquidity changes, injuries, announcements, news, or other event-specific developments.
