PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

All platforms utilize the same resolution criteria based on official MLB results and address cancellation/postponement scenarios consistently.Primary resolution logic: Official information from MLB (https://www.mlb.com/)

Core resolution logic:

  • The market resolves to the team that wins the 2026 MLB World Series.
  • If a team is mathematically eliminated from playoff contention, its market resolves to 'No'.
  • If the 2026 MLB season is cancelled or postponed after December 31, 2026 ET, or no winner is declared, the 'Other' market resolves positively.

Edge cases & clarifications:

  • Postponement: If the season is significantly delayed but still completed within 2026, resolution will still occur based on the eventual winner.
  • Tie: In the extremely unlikely event of a tie, MLB's official tie-breaking procedures will determine the winner for resolution purposes.
Timing: Resolution will occur immediately following the conclusion of the 2026 MLB World Series, or upon official cancellation/postponement announcement by MLB.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.

Frequently asked questions

Prediction market odds, like those found in this market, often differ from traditional sportsbook odds due to the incentives and information sources involved. Sportsbooks primarily aim to balance their books and profit from margins, while prediction markets incentivize participants to express their true beliefs. This can lead to prediction markets being more accurate, particularly when incorporating a wide range of information and expert opinions. However, sportsbooks often have lower transaction costs and wider accessibility. The 1.4 difference between the two can be an indicator of market sentiment and potential value.

Prices on Polymarket and Predict may diverge for several reasons. Polymarket and Predict 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 attracts a different user base with varying levels of expertise and access to information. Trading volume and liquidity also play a role; a market with higher volume on one platform tends to have more stable and efficient pricing. Currently, Polymarket currently favors Will the Milwaukee Brewers win the 2026 World Series? at 65.4%, while Predict leans toward Will the Milwaukee Brewers win the 2026 World Series? at 66.8%. These differences reflect the unique dynamics of each platform’s trading activity and participant perspectives.

This market resolves around Oct 31, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The winning team of the 2026 MLB World Series, as officially declared by Major League Baseball, will determine the result of this market. Trading will cease once the official results are available, and payouts will be distributed accordingly. The market’s outcome is based on the universally accepted result of the championship series, ensuring a transparent and verifiable process.

Numerous factors could influence the odds in this market over the next few years. Significant player trades, injuries to key players, managerial changes, and team performance during the regular season and playoffs will all be closely watched. Unexpected developments in team ownership or financial stability could also impact perceptions. Furthermore, major rule changes implemented by MLB could shift competitive advantages. Any news that alters the perceived probability of a team winning the World Series is likely to cause movement in this market.
