This market will resolve to “Yes” if OpenAI makes GPT-4 available to users as a generally available public release (including any beta or test versions) by May 31, 2023, 11:59:59 PM ET. Otherwise this question will resolve to “No”. GPT-4 refers to a product that is explicitly named GPT-4, or is a successor to GPT-3 in the way that GPT-3 was a successor to GPT-2; it cannot be branded as GPT3.5 or a version of GPT-3. Closed beta or a non-public release will not suffice to resolve this market to "Yes." The primary resolution source for this market will be the official OpenAI website (https://openai.com/), however a consensus of credible reporting may be used.
