PredictionHero - Resolution Divergence Alerts (RDA)
Divergence Detected
Issue:
Kalshi market resolves YES for ALL possible halftime outcomes (West Ham win, Crystal Palace win, or draw), making it logically incoherent and fundamentally unresolvable. Polymarket markets are mutually exclusive binary outcomes tied to specific team results.Hero Tip:
Avoid the Kalshi market entirely—it violates basic market logic by guaranteeing a YES resolution regardless of match outcome. Trade only the three Polymarket binary markets, which are properly structured as mutually exclusive outcomes.Critical Divergence Points:
Kalshi:
All three resolution conditions resolve to YES: 'If West Ham is the winner...then YES', 'If Crystal Palace is the winner...then YES', 'If Tie is the result...then YES'. This creates a logical contradiction where the market always resolves YES, making it impossible to lose or differentiate outcomes.Polymarket:
Three separate binary markets with mutually exclusive outcomes: West Ham leading at halftime (YES/NO), Crystal Palace leading at halftime (YES/NO), and Draw at halftime (YES/NO). Each market resolves YES only if its specific condition occurs, otherwise NO. Resolution source is official governing body statistics or credible consensus within 24 hours.
