PredictionHero - Resolution Divergence Alerts (RDA)
Unified Resolution Criteria (Consistent across platforms)
All markets across Polymarket and Kalshi use identical resolution logic: official final score from mlssoccer.com after 90 minutes plus stoppage time, with consistent handling of postponements (remain open) and cancellations (50-50 split).
Primary resolution logic:
mlssoccer.com official final score; fallback to consensus credible reporting if official statistics not published within 2 hours of match conclusionCore resolution logic:
- Spread: Houston Dynamo (-2.5) resolves YES if Houston wins by 3+ goals, otherwise NO
- Spread: Houston Dynamo (-1.5) resolves YES if Houston wins by 2+ goals, otherwise NO
- Spread: FC Dallas (-2.5) resolves YES if Dallas wins by 3+ goals, otherwise NO
- Spread: FC Dallas (-1.5) resolves YES if Dallas wins by 2+ goals, otherwise NO
- Over/Under 1.5: Over if combined goals >= 2, Under if < 2
- Over/Under 2.5: Over if combined goals >= 3, Under if < 3
- Over/Under 3.5: Over if combined goals >= 4, Under if < 4
- Over/Under 4.5: Over if combined goals >= 5, Under if < 5
- Both Teams to Score: Yes if each team scores >= 1 goal, No if either team scores 0
Edge cases & Clarifications:
- Game Postponement: Market remains open until the game is completed; no early resolution
- Game Cancellation (No Make-up): Market resolves 50-50 (split equally between Yes and No outcomes)
- Incomplete Match: If game is started but not completed, resolution uses official final score published on mlssoccer.com
- Official Stats Delay: If mlssoccer.com does not publish final statistics within 2 hours of match conclusion, consensus of credible reporting sources may be used
- Scope of Play: All markets measure only the first 90 minutes of regular play plus stoppage time; extra time and penalties are excluded
Timing:
Resolution occurs after match conclusion (90 minutes plus stoppage time) once official final score is published on mlssoccer.com or confirmed via credible reporting consensus within 2 hoursOur PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms.
