Rules
If the named outcome serves as lead-left underwriter on OpenAI's initial public offering in the United States before Jan 1, 2028, then the market resolves to Yes.
Settles via:SEC EDGAR database filings
- If two or more underwriters are presented on the cover of the final prospectus as jointly occupying the lead-left position, such that no single underwriter is uppermost-and-leftmost (for example, two names sharing equal top billing), then each such underwriter's outcome resolves to $1/(the number of tied underwriters), rounded down, for “Yes”, and “No” will be paid $1 minus the Yes value.
- If Citigroup serves as lead-left underwriter on OpenAI's initial public offering in the United States before Jan 1, 2028, then the market resolves to Yes.
