Will Anthropic or OpenAI IPO first?

Will Anthropic or OpenAI IPO first? is a finance prediction market tracking which of the two leading AI companies will complete an initial public offering before the other. The event asks traders to forecast whether Anthropic or OpenAI will list first on a recognized stock exchange, with resolution based on official company announcements and credible news coverage. The market also defines a 50-50 outcome if neither company goes public by December 31, 2027, if both IPO on the same calendar date, or if both become unable to complete an IPO through acquisition, merger, or absorption by a public company. As of the latest data, market probability is around 63.5% for one side of the forecast, indicating sentiment is leaning toward a particular expected outcome, though the result remains uncertain. The prediction market is relevant to anyone following AI business strategy, OpenAI, Anthropic, Sam Altman, and the broader IPO landscape.
