PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

Both platforms consistently resolve to the team that wins the NL East division according to MLB official standings.Primary resolution logic: Official information from Major League Baseball (https://www.mlb.com/)

Core resolution logic:

  • The market resolves to 'Yes' for the team that wins the 2026 NL East division.
  • MLB's official standings and tie-breaking procedures will be used to determine the winner.
  • If the 2026 MLB regular season is cancelled or postponed past October 31, 2026, the market resolves to 'Other'.

Edge cases & clarifications:

  • Tie: If two or more teams tie for first place, MLB's official tie-breaking rules will be used to determine the division winner. The market will resolve to the team declared the winner by MLB.
  • Cancelled Season: If the 2026 MLB regular season is cancelled or postponed past October 31, 2026, the market will resolve to 'Other'.
Timing: Resolution will occur after the conclusion of the 2026 MLB regular season and official declaration of the NL East division winner by Major League Baseball.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 2026 MLB National League East division. In the event of a tie, this market will resolve according to the official winner as determined by MLB rules. If multiple winners are announced then this market will resolve to the team whose listed nickname comes first alphabetically. If at any point it becomes impossible for a listed team to be named the 2026 National League East division champion per the rules of the MLB (e.g., they are eliminated in the playoffs), the corresponding market will resolve to “No”. If the 2026 MLB regular season is cancelled, postponed after October 31, 2026, 11:59 PM ET, or there is otherwise no winner declared within that timeframe, this market will resolve to “Other”. The primary resolution source will be official information from Major League Baseball (https://www.mlb.com/); however, a consensus of credible reporting may also be used.

Kalshi

The 2026 NL East Division Winner is determined by regular season performance. Any of the five teams in the division—Washington, Miami, Atlanta, Philadelphia, or New York Mets—may win the division title by achieving the best win-loss record during the regular season. The market resolves to Yes for whichever team finishes atop the division standings.

Frequently asked questions

Prediction market odds often reflect the collective wisdom of informed traders, potentially offering a different perspective than traditional sportsbooks. Sportsbooks set lines to balance action and profit, incorporating a margin, while this market's prices are driven purely by supply and demand. This can lead to discrepancies, especially when public sentiment diverges from expert analysis. While sportsbooks may initially favor certain teams, the prediction market can adjust rapidly as new information emerges and traders refine their assessments of the NL East championship race. It's a valuable comparison point for anyone following the competition.

Prices on Polymarket and Kalshi can diverge due to several factors. Polymarket and Kalshi can show different implied probabilities for the same outcome because of liquidity, fee structure, participant mix, and how each venue defines the contract. Each platform has its own user base with varying levels of expertise and information, leading to different interpretations of the same data. Trading volume also plays a role; lower volume on one platform can result in greater price volatility. Furthermore, the specific rules and fee structures of each platform can influence trading behavior. While both platforms ultimately track the same event—the outcome of the NL East championship race—these differences contribute to potentially varied pricing signals.

Numerous factors could influence the price of this market. Key player injuries, significant trades, or changes in team performance could all shift expectations. Unexpected developments during the season, such as a team exceeding or underperforming projections, will likely cause price adjustments. News regarding managerial changes or shifts in team ownership could also play a role. As the season progresses and more data becomes available, traders will continuously update their assessments of each team’s chances in the NL East championship race, leading to dynamic price movements.
