GPT-5 not announced in 2024?

This market will resolve to “Yes” if OpenAI does NOT announce the completion of ChatGPT-5 and/or GPT-5 between January 1, 2024, 12:00 AM ET, and December 31, 2024, 11:59:59 PM ET. Otherwise, this market will resolve to “No”. Only official publicly issued communications from OpenAI will count towards this market's resolution. Unofficial statements or interviews by board members or employees, including Sam Altman, will not suffice for a "Yes" resolution. This market may not resolve to "Yes" until its timeframe has expired and the completion of GPT-5 has not yet been announced. GPT-5 refers to a product that is explicitly named GPT-5, or is a successor to GPT-4 in the way that GPT-4 was a successor to GPT-3. GPT-4.5 or such products will not count for this market's resolution. The primary resolution source for this market will be official OpenAI communications from its website https://openai.com/.
