Intro

This market tracks the winner of the 2026 World Series MVP award, as determined by MLB’s official selection process. Currently, the consensus probability that William Contreras will win the award is 100.0%. This forecast is an aggregation of data from Kalshi and Polymarket, and will resolve based on official information from MLB. Should the winner not be among the listed players, the “Other” outcome will resolve positively. Keep an eye on the announcement of the award winner following the conclusion of the 2026 World Series, with a resolution date estimate of December 31, 2026.

PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Polymarket includes an 'Other' option for players not listed, while Kalshi only considers the listed players. Polymarket also specifies cancellation criteria.Hero tip: Be mindful of the 'Other' option on Polymarket. If you believe a player not listed on Polymarket has a good chance of winning, consider that market. On Kalshi, only the listed players are in contention.

Critical divergence points:

  • Polymarket: Resolves 'Yes' if the listed player wins the award. Includes an 'Other' market that resolves 'Yes' if a player not on the list wins. Resolves 'No' for all listed players if the series is cancelled or no winner is announced by November 15, 2026.
  • Kalshi: Resolves 'Yes' if the listed player wins the award. No explicit handling of players not listed or cancellation of the World Series.
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 to the player who wins the Willie Mays World Series MVP Award for the 2026 World Series. If the winner is not a listed player, the "Other" market will resolve to "Yes". If more than one player is named the winner of the award, each listed player's market, including those of the co-winners, will resolve to "No" and the "Other" market will resolve to "Yes". If the 2026 World Series is cancelled, or no winner of the award is announced by November 15, 2026, 11:59 PM ET, each listed player's market will resolve to "No" and the "Other" market will resolve to "Yes". The resolution source for this market will be official information from MLB; however, a consensus of credible reporting may also be used.

Kalshi

Each market corresponds to an individual player winning the World Series Most Valuable Player Award for the 2026 season. If the specified player is officially named the winner, that market resolves to 'Yes.' If two or more players are named co-winners, all co-winners' 'Yes' contracts pay $1 divided by the number of co-winners (N), and all 'No' contracts pay $1 minus that payout amount. The markets operate independently, meaning the resolution of one does not affect the others. Kalshi explicitly states it is not affiliated with Major League Baseball, and all trademarks remain the property of their respective owners.

Frequently asked questions

Numerous factors could influence the odds in this market. Player injuries are a significant catalyst, as the absence of a key performer can dramatically shift expectations. Strong or weak performances during the League Championship Series, leading up to the World Series, will also impact trader sentiment. Unexpected pitching matchups or managerial decisions could also play a role. Furthermore, any news regarding player health, team dynamics, or strategic adjustments could move the market. Significant volume changes on either Polymarket or Kalshi could also indicate shifts in market opinion.
