PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

Both Polymarket and Kalshi define a walk-off as a game ending when the home team takes the lead in their final at-bat, and both platforms share the same cancellation/completion date criteria.Primary resolution logic: Official information from MLB; consensus of credible reporting

Core resolution logic:

  • The number of walk-off wins in the 2026 MLB Postseason will be counted.
  • Each market will resolve to 'Yes' if the number of walk-offs is greater than or equal to the market's threshold (e.g., 1+, 2+, 3+).
  • If the 2026 MLB Postseason is cancelled or the World Series is not completed by November 15, 2026, 11:59 PM ET, all markets will resolve to 'No'.

Edge cases & clarifications:

  • Tiebreaker Games: Tiebreaker or 'Game 163' games are explicitly excluded from the definition of the 2026 MLB Postseason and will not be counted towards walk-off totals.
  • Walk-off via Error/Balk: A walk-off win can occur due to a hit, walk, hit by pitch, error, or balk – any play that gives the home team the lead in their final at-bat.
Timing: Resolution will occur after the conclusion of the 2026 MLB World Series, or if the postseason is cancelled/incomplete by November 15, 2026, 11:59 PM ET.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 "Yes" if the total number of walk-off wins during the 2026 MLB Postseason equals or exceeds the listed number. Otherwise, this market will resolve to "No". A "walk-off win" is a game that ends the moment the home team takes the lead during its final at-bat, including in any extra inning. Any play producing that lead counts, including a hit, a walk, a hit by pitch, an error, or a balk. If no walk-off wins occur during the 2026 MLB Postseason, every market in this event will resolve to "No". Only walk-off wins in 2026 MLB Postseason games will count toward this market. The 2026 MLB Postseason comprises the Wild Card Series, the Division Series, the League Championship Series, and the World Series. Regular season games, exhibition games, and any tiebreaker or "Game 163" will not be considered part of the 2026 MLB Postseason. If the 2026 MLB Postseason is cancelled, or the World Series has not concluded by November 15, 2026, 11:59 PM ET, this market will resolve to "No". The resolution source for this market will be official information from MLB; however, a consensus of credible reporting may also be used.

Kalshi

Multiple markets across this event evaluate the number of walk-off victories occurring during the 2026 Pro Baseball Playoffs. A walk-off is defined as a game concluding when the home team scores the winning run in the bottom half of the ninth inning or any extra inning, with that run ending the game immediately. Regardless of how the winning run is scored, each instance counts toward the relevant market. Markets resolve to 'Yes' if the total number of walk-offs reaches or exceeds the specified threshold (1, 2, 3, 4, or 5), with all markets sharing the same definition of a qualifying walk-off scenario.

Frequently asked questions

This dashboard aggregates real-time predictions on the MLB walk-off market from multiple platforms, including Polymarket and Kalshi. It displays a consensus view of the probability of different walk-off totals occurring during the 2026 MLB Postseason. Currently, the combined volume across these platforms is $26,682, with $2,849 traded in the last 24 hours. The dashboard helps visualize how traders are pricing the likelihood of various outcomes, offering a broader perspective than any single platform. It’s a great way to understand the collective wisdom of the crowd regarding this exciting aspect of postseason baseball.

Several factors could influence the price of this market. Significant injuries to key players on contending teams could impact their ability to win close games, potentially increasing the likelihood of walk-offs. Changes in MLB rule interpretations regarding balks or interference could also play a role. Unexpected weather patterns during the postseason, particularly in cities prone to rain delays, might create more opportunities for walk-off scenarios. Finally, major upsets in the early rounds of the playoffs could shift expectations and alter the perceived probabilities within this market.
