If Sean O'Malley is officially listed to compete on the UFC 2026 White House event fight card before Jul 4, 2026, then the market resolves to Yes. The fighter must be officially announced by the UFC to compete on the specified event card. This includes main card, preliminary card, or early preliminary card positions. The market resolves to Yes upon official UFC announcement even if the fighter subsequently withdraws due to injury, weight cut issues, or other circumstances. Replacement fighters added to the card also trigger Yes resolution. Being rumored for the card, attending as a spectator, or fighting on a different UFC event the same weekend does not qualify. If the event is canceled or delayed beyond the expiration date, the market resolves to last fair price. This market will close and expire early if the fighter is officially announced for the card.
