Resolution criteria

• This market resolves each threshold bracket independently (YES or NO) based on the market capitalization of OpenAI at the official market close of its first day of regular public trading (IPO day), provided the listing occurs before January 1, 2028, 00:00 UTC.

• Precondition: If OpenAI does not complete an initial public offering (IPO) or direct listing on a recognized major stock exchange (e.g., NASDAQ, NYSE) before January 1, 2028, ALL answer options will resolve NO.

• Market Cap Determination:

  • The closing market cap will be calculated as:
    Closing Share Price on Day 1 × Total Common Shares Outstanding (diluted/basic as reported in the final prospectus / SEC Form 424B4)

  • The primary source of truth will be the closing valuation reported by reputable financial data aggregators (such as Bloomberg, Reuters, or Google Finance). If reporting differs slightly due to share count definitions (basic vs. fully diluted), the consensus reported in major financial press coverage of the first day's close will be used.

• Multiple Choice Evaluation: Because this is an independent multiple choice market with "or more" phrasing, any bracket equal to or below the final verified IPO closing valuation will resolve YES. All brackets strictly above that valuation will resolve NO.

  • Example: If OpenAI completes an IPO before 2028 and closes day 1 at a market cap of $1.35 trillion, the options "$1 trillion or more", "$1.1 trillion or more", "$1.2 trillion or more", and "$1.3 trillion or more" resolve YES, while "$1.4 trillion or more" and above resolve NO.
