GPT-5.3 released by January 31, 2026?

This market will resolve to "Yes" if OpenAI's GPT-5.3 model is made available to the general public by January 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No." For this market to resolve to "Yes," GPT-5.3 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-5.3 refers to a product explicitly named GPT-5.3 (e.g., ChatGPT-5.3o, would count), or one that is recognized as a successor to GPT-5.2, similar to the progression from GPT-5.1 to GPT-5.2. Products labeled as GPT-6 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.
