Description

This prediction group concerns the winner of the 2027 NCAA Division I Men's Basketball Tournament, commonly known as March Madness. Participants are predicting which university's basketball team will be crowned national champion.

PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi lists all possible teams as resolving 'Yes' if they win, while Polymarket has a more limited list and an 'Other' option for teams not listed.Hero tip: Consider the likelihood of a team outside of Polymarket's listed options winning. Kalshi offers broader coverage, but Polymarket's 'Other' option could be valuable if you anticipate an upset.

Critical divergence points:

  • Polymarket: Resolves to 'Yes' if a listed team wins the 2027 NCAA Division I Men's Basketball Tournament. Includes an 'Other' option if the champion is not listed. Source: https://www.ncaa.com
  • Kalshi: Resolves to 'Yes' if any of the listed 73 teams wins the 2026-27 Division 1 Men's College Basketball National Championship.
Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms. They do not replace or supersede the official rules and description of any prediction market. Users are solely responsible for reviewing and understanding the applicable rules and resolution criteria before placing any trade or bet. If you notice a potential inconsistency, discrepancy, or error in an alert, please report it to our team so we can review and improve the accuracy of our data.

Polymarket

This market will resolve according to the team that wins the 2027 NCAA Division I Men's Basketball Tournament (the national champion). If at any point it becomes impossible for a listed team to win the 2027 tournament (e.g., they are eliminated or fail to qualify), the corresponding market will resolve to "No". If the 2027 NCAA Division I Men's Basketball Tournament is cancelled, postponed after April 19, 2027, 11:59 PM ET, or there is otherwise no champion declared within that timeframe, this market will resolve to "Other". The primary resolution source will be official information from the NCAA (https://www.ncaa.com); however, a consensus of credible reporting may also be used.

Kalshi

The market resolves to Yes if the specified team wins the 2026-27 Division 1 Men's College Basketball National Championship. Resolution is based on the official NCAA tournament outcome. Kalshi is not affiliated with or endorsed by the NCAA.
