If Billie Eilish is on the The Tonight Show Starring Jimmy Fallon 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 The Tonight Show Starring Jimmy Fallon (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.
