This market asks whether OpenAI will publicly release GPT-6 by September 30, 2026. It is centered on a very specific product milestone, not just whether OpenAI mentions the next model internally or shows it to a limited group.
The question is whether a model explicitly treated as GPT-6 will be made available to the general public by the deadline of September 30, 2026 at 11:59 PM ET. The rules say that open beta access or open rolling waitlist signups would count, but a closed beta or private access would not. The market also says a successor clearly recognized as the next step after GPT-5 could qualify, while names like GPT-5.5 would not.
OpenAI has a history of naming major model jumps in a way that matters to users, developers, and the wider AI industry, so the timing of the next numbered release is uncertain and closely watched. People following this market are essentially weighing whether OpenAI will reach a public GPT-6 launch within the stated window, or whether the company will keep iterating on earlier models instead. The disagreement comes from both the uncertain product timeline and the exact naming and access rules that determine what counts as a release.
An official OpenAI announcement saying GPT-6 is available to the public would be the clearest price-moving development, especially if it includes broad access rather than a restricted preview. Pricing could also move if OpenAI publicly launches a product that is widely understood to be the GPT-5 successor under a GPT-6-style name or equivalent branding. On the other hand, signs of a longer research phase, a limited invite-only rollout, or a differently named intermediate version would make a September 30, 2026 resolution less likely under these rules.
The current market price implies roughly a 47% 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.

View marketThe key source of truth is OpenAI’s own public communication, with credible reporting used only as backup if needed. Readers should watch for the exact product name, the access model, and whether the launch is described as generally available to the public rather than private or invitation-only. The deadline is September 30, 2026 at 11:59 PM ET, and the main ambiguity risk is whether a new model is truly GPT-6 under the market’s naming standard or just another step in the GPT-5 line.

This market is currently listed with an end date of Jun 30, 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-6 model is made available to the general public by September 30, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No." For this market to resolve to "Yes," GPT-6 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 clearly defined and publicly announced by OpenAI as being accessible to the general public. GPT-6 refers to a product explicitly named GPT-6 (e.g. ChatGPT-6o would count), or one that is recognized as a successor to GPT-5, similar to the progression from GPT-3 to GPT-4. Products labeled as GPT-5.5 or similar will not count for this market's resolution. The primary resolution source for this market will be official information from OpenAI, with additional verification from a consensus of credible reporting.
