Resolution rules

This market will resolve according to the public ticker symbol used by OpenAI in an IPO (Initial Public Offering) by December 31, 2027, 11:59 PM ET. An official announcement from OpenAI that it will IPO under a specific ticker symbol will be sufficient to resolve this market. If a ticker used by OpenAI in a qualifying IPO is a variant of a ticker symbol listed in this market group with additional letters to denote a specific class of shares, it will be considered to be that ticker (e.g. if OpenAI uses a ticker symbol of $OPAI.A or $OPAIA, this market will resolve to $OPAI). If OpenAI announces an IPO with multiple tickers that are not considered the same ticker under the previous rule (i.e. $OPAI.A and $OPAI.B would be considered the same ticker), this market will remain open until OpenAI's first day of public trading and will resolve according to the ticker symbolizing the security class with the greatest market capitalization. Market capitalization is calculated as the number of shares outstanding multiplied by the closing share price on the first trading day. If this also results in a tie, this market will resolve according to the ticker symbol that comes first in alphabetical order. If OpenAI IPOs with a non-listed ticker, or does not IPO or officially announce an IPO and ticker symbol by December 31, 2027, 11:59 PM ET, this market will resolve to "Other." The primary resolution source for this market will be official information from OpenAI and the primary exchange…
