PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

Both Polymarket and Kalshi define resolution based on the same 90+ minute timeframe and have consistent fallback resolution procedures.Primary resolution logic: Official statistics of the event as recognized by the governing body or event organizers (NWSSL).

Core resolution logic:

  • The market resolves to 'Yes' for the 'Portland Thorns FC win' market if Portland Thorns FC has the higher score at the end of 90 minutes plus stoppage time.
  • The market resolves to 'Yes' for the 'Chicago Stars FC win' market if Chicago Stars FC has the higher score at the end of 90 minutes plus stoppage time.
  • The market resolves to 'Yes' for the 'Draw' market if the scores are tied at the end of 90 minutes plus stoppage time.
  • If the game is postponed, the markets remain open until the game is completed.
  • If the game is canceled entirely, the 'Portland Thorns FC win' and 'Chicago Stars FC win' markets resolve to 'No', while the 'Draw' market resolves to 'Yes'.

Edge cases & clarifications:

  • Postponement: Markets remain open until the game is completed. Resolution will then follow the standard win/draw/loss logic.
  • Cancellation: The 'Portland Thorns FC win' and 'Chicago Stars FC win' markets resolve to 'No'. The 'Draw' market resolves to 'Yes'.
  • Data Discrepancies: The primary resolution source is official statistics. If unavailable, Flashscore, Sofascore, or a consensus of credible reporting will be used. Revisions to official scores after market resolution will not be considered.
Timing: Resolution will occur as soon as official statistics are available, or within 2 hours of the event's conclusion if official data is delayed, falling back to Flashscore, Sofascore, or consensus reporting as needed.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 represented in this market, often differ from traditional sportsbook odds due to the nature of how they are created. Sportsbooks set lines to balance their risk and ensure profit, while prediction markets are driven by the collective wisdom of traders who are incentivized to accurately forecast the outcome. This can lead to prediction markets being more accurate, especially when a significant amount of volume is traded. However, sportsbook odds are readily available and often reflect public perception, which can sometimes diverge from the more informed opinions found in prediction markets.

On Polymarket, this market is priced through a continuous auction mechanism, while Kalshi uses a different order book structure. 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. This difference in mechanisms can lead to price discrepancies, even when both platforms are tracking the same underlying event. Additionally, the user base and trading activity on each platform can vary, influencing the price discovery process. Market sentiment and information flow also aren’t necessarily identical across both venues, contributing to differing probabilities for the same outcome.

Several factors could influence the price of this market before it resolves. Any news regarding player injuries, team form, or changes in coaching staff could shift expectations. Unexpected weather conditions on match day could also play a role. Furthermore, significant trading volume on either Polymarket or Kalshi driven by new information or a change in sentiment could cause the odds to move. Major upsets in other related matches could also indirectly impact trader confidence and influence the market’s direction.
