This market will resolve to “Yes” if any team that is a number 16 seed wins any game during any round of the 2026 Men’s Basketball NCAA Tournament, starting with the round of 64. First Four games will not be considered. Otherwise, this market will resolve to “No”. If an opponent of any number 16 seed forfeits prior, or during the matchup, this market will resolve to “Yes”. If the 2026 Men’s Basketball NCAA Tournament is cancelled, postponed after April 30, 2026, 11:59 PM ET, or is partially completed with otherwise no winner declared within that timeframe, this market will resolve to 50-50. The resolution source for this market will be official information from the NCAA; however, a consensus of credible reporting may also be used.
