This market asks which specific game from the Men's College Basketball Tournament will be judged the "Biggest upset." It matters because it aggregates trader expectations about which upset will be most significant and highlights how perceptions change during the tournament.
The NCAA single-elimination format produces frequent upsets, and "biggest upset" is often measured by seed differential, pregame rankings, or the magnitude of the surprise relative to expectations. Past tournaments have produced memorable upsets that altered brackets and narratives; this market lets participants express views about which upset will be the most notable in the current tournament.
Market prices signal the collective view of which outcome market participants believe will be judged the biggest upset; they update as games, injuries, and other information arrive and should be read as relative indicators rather than guarantees.
The event page contains the market's official definition (for example seed differential, ranking gap, or other criteria); outcome resolution follows that definition and any applicable platform resolution rules.
Resolution typically occurs after the tournament stage specified by the market ends and official results are available; check the market page for updates on the close date and the platform's resolution timeline.
Each outcome corresponds to a specific candidate game or category listed on the market page; view the outcome labels on the event page to see the exact games or descriptions that traders can select.
Tie resolution is governed by the platform's rules—commonly outcomes that meet the same official metric may be split or resolved according to a pre-specified tiebreaker; consult the market's resolution rules for the exact procedure.
Consider the reliability and timing of the information and its likely impact on the specific game's competitiveness and perceived surprise; such news often moves market prices quickly, but remember the market resolves according to the official game result and any postgame adjudications recorded by tournament organizers.
