# Which bank will lead OpenAI's IPO? — Before Jan 1, 2028

Live · $23,215 traded · listed on Kalshi

## About

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.
