Resolution relies on a consensus of credible reporting and official announcements rather than a specific exchange registry or regulatory filing. The criteria define an IPO as the first sale of stock to the public on any recognized stock exchange. Participants should note an early resolution exception: if OpenAI is acquired by an already public company, the market resolves immediately to No rather than waiting until the deadline.
