Resolution rules

Rules as stated by Polymarket, reproduced verbatim. Convexly has not independently reviewed them and does not endorse them; the rating's resolution-reliability pillar treats rule text as present but not independently reviewed.

In the UEFA Champions League qualifying tie between Olympique Lyonnais and Fenerbahçe SK, with the deciding leg scheduled for August 26 at 3:00 PM ET: This market will resolve to "Olympique Lyonnais" if Olympique Lyonnais is the team that officially advances from this two-legged tie, based on aggregate score across both legs, to the next stage of the UEFA Champions League. This market will resolve to "Fenerbahçe SK" if Fenerbahçe SK is the team that officially advances from this two-legged tie to the next stage of the UEFA Champions League. This includes advancement after regulation, extra time, a penalty shoot-out, or an official ruling by the competition organizer such as forfeit, abandonment, or disqualification. If either leg is postponed, this market will remain open until the tie has been completed or a team is officially declared to advance. If the tie is canceled entirely and no team advances, this market will resolve 50-50. The primary resolution source for this market is the official statistics published by the governing body or event organizers. If the governing body or event organizers have not published final statistics within 24 hours of the event's conclusion, data from Flashscore may be used; if Flashscore data is unavailable, data from Sofascore may be used; if neither is available, a consensus of credible reporting may be used. Revisions to officially published final statistics made after market resolution will not be considered in determining the outcome. If no acceptable data is available within 48 hours of the event's conclusion, this market will resolve 50-50.Show the full rules text
