Description

This event tracks the greatest seeding disadvantage overcome by any winning team throughout the full 2026 Men's College Basketball Tournament. A team with a lower seed that defeats higher-seeded opponents on its path to victory would demonstrate a seeding disadvantage, and this market measures the largest such disadvantage achieved by any tournament winner.
