The definition of an IPO as the first sale of stock to the public on a recognized exchange provides clear criteria, but relying on a consensus of credible reporting rather than a specified regulatory filing or exchange database introduces decider discretion. Participants should note the early resolution clause: if OpenAI is acquired by an already-public company prior to the deadline, the market will immediately resolve to No rather than waiting until the end of 2026. Alternative public listing mechanisms, such as direct listings or SPAC mergers, are not explicitly separated from traditional IPOs, so resolution would depend on reporting interpreting them as a public stock sale.
