PredictionHero - Resolution Divergence Alerts (RDA)
Unified Resolution Criteria (Consistent across platforms)
Both Polymarket and Kalshi use identical resolution logic: the market resolves based on the final outcome of the CD Nacional vs. FC Alverca match on April 18, 2026, after 90 minutes plus stoppage time, with the same primary resolution source (official governing body statistics or credible reporting consensus within 2 hours).
Primary resolution logic:
Official statistics from Liga Portugal (ligaportugal.pt) as recognized by the Portuguese football governing body; if unavailable within 2 hours post-match, credible reporting consensus.Core resolution logic:
- Polymarket FC Alverca market resolves YES if and only if FC Alverca wins the match; resolves NO otherwise.
- Polymarket CD Nacional market resolves YES if and only if CD Nacional wins the match; resolves NO otherwise.
- Polymarket Draw market resolves YES if and only if the match ends in a draw; resolves NO otherwise.
- Kalshi market resolves YES if any of the three outcomes occurs (Nacional win, Alverca win, or Tie), meaning it will always resolve YES.
- Exactly one of the three Polymarket outcome markets will resolve YES; the Kalshi market always resolves YES.
Edge cases & Clarifications:
- Match Postponement: If the match is postponed, Polymarket markets remain open until the match is completed. Kalshi does not explicitly address postponement but references the match originally scheduled for April 18, 2026.
- Match Cancellation: If the match is canceled entirely with no make-up game, Polymarket's FC Alverca and CD Nacional markets resolve NO, while the Draw market resolves YES. Kalshi does not explicitly address cancellation.
- Scope: Regular Time Only: All markets resolve based on the outcome after 90 minutes plus stoppage time only; extra time and penalties are excluded from resolution.
Timing:
Resolution occurs upon official Liga Portugal announcement of the final match result, or within 2 hours post-match conclusion via credible reporting consensus if official statistics are not published.Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms.
