Only instances where Conor McGregor officially participates in an official UFC-sanctioned fight will count toward a “Yes” resolution. The resolution source for this market will be official information from the UFC; however, a consensus of credible reporting may also be used.The confirmed July 11, 2026, welterweight main event against Max Holloway at UFC 329 during International Fight Week in Las Vegas stands as the dominant driver behind the 87% implied probability on Yes.
