Will GPT-6 be released by September 30, 2026?

The market is pricing an 82% probability of GPT-6 release by late September 2026, but the extreme 2331% implied yield on "No" positions signals severe mispricing or illiquidity on the downside—only $19.8k in 24h volume and $3.7M open interest suggest thin liquidity that may not reflect true conviction. The 389% realized volatility and sharp 6-point rally over seven days (76¢ to 82¢) indicate recent bullish sentiment, though with 71 days to resolution and a neutral regime score, the market appears to be pricing in OpenAI's historical release cadence rather than accounting for potential development delays or strategic timing changes.

Resolution rules

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.
