Description

This group forecasts which MLB player will hit the most home runs during the 2026 MLB Postseason, encompassing the Wild Card Series, Division Series, League Championship Series, and World Series. In the event of a tie, slugging percentage is used as a tiebreaker.

PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: The player lists differ significantly between platforms, creating SKU risk. Polymarket includes an 'Other' option, while Kalshi only lists specific players.Hero tip: If you believe a player not listed on Kalshi has a strong chance of leading in home runs, focus on Polymarket's 'Other' market. Otherwise, compare player-specific odds across both platforms.

Critical divergence points:

  • Polymarket: Resolves based on the player with the most home runs in the 2026 MLB Postseason. Tiebreaker is slugging percentage. Includes an 'Other' option for players not explicitly listed. Allows for 'Player A' through 'Player BS' options.
  • Kalshi: Resolves to 'Yes' only if a specific listed player leads in home runs during the 2026 MLB Postseason. No tiebreaker or 'Other' option is provided. Only lists a subset of potential players.
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 in favor of the player that finishes the 2026 MLB Postseason with the most home runs. In the event of a tie for the most home runs, this market will resolve in favor of the tied player with the higher slugging percentage across the 2026 MLB Postseason. If a tie still persists, each tied player's market will resolve to "No" and the "Other" market will resolve to "Yes". Only home runs 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. The "Other" market will resolve to "Yes" if the player who leads is not among the listed players. If the 2026 MLB Postseason is cancelled, or the World Series has not concluded by November 15, 2026, 11:59 PM ET, every named 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, resolving to 'Yes' if that specific player leads all of Pro Baseball in home runs scored during the 2026 postseason. Only statistics recorded in playoff games are considered. If a player does not participate in any playoff games—due to injury, suspension, retirement, or other reasons—the market resolves to 'No'. In cases of exact ties where no single leader is declared, all tied participants receive a proportional payout. Statistical corrections are only applied if made before the market expiration date. Kalshi explicitly disclaims any affiliation with the governing league, and all trademarks remain the property of their respective owners.

Frequently asked questions

This dashboard tracks the MLB home run leader market across multiple prediction platforms, providing a consensus view of who is most likely to hit the most home runs during the 2026 MLB Postseason. Currently, the combined volume across Polymarket and Kalshi is $48,158, with $5,805 traded in the last 24 hours. We aggregate probabilities from each platform to show the overall market-weighted chance of various players leading in home runs. This allows for a comprehensive understanding of market sentiment beyond any single venue.

Several factors could significantly shift the probabilities in this market. Player injuries are a major catalyst, as the absence of a key power hitter would dramatically alter the landscape. Significant trades could also impact the odds, particularly if a team acquires a player known for their home run hitting ability. Preseason performance and spring training statistics may offer early indicators, though their predictive power is limited. As the 2026 MLB season progresses, real-game performance and any changes in team lineups will be closely watched by traders.
