If Billie Eilish is on Jimmy Kimmel Live! before Jan 1, 2027, then the market resolves to Yes. If Billie Eilish appears solely in an advertisement, or solely via a prerecorded audioclip that was not recorded for purposes of Jimmy Kimmel Live! (e.g., the host playing a portion of a speech or song excerpt by Billie Eilish), the Payout Criterion is not satisfied. This market will close and expire early if the event occurs.
