PredictionHero - Resolution Divergence Alerts (RDA)
Divergence Detected
Issue:
Kalshi market contains a logical contradiction: both Philadelphia winning AND Boston winning resolve to Yes, making the market fundamentally unresolvable and creating mutual exclusivity failure.Hero Tip:
Do not trade the Kalshi market. The resolution logic is broken—it resolves Yes regardless of outcome. Polymarket is the only tradeable venue with coherent binary logic (76ers win → 76ers, Celtics win → Celtics).Critical Divergence Points:
- Polymarket: Clean binary resolution: If 76ers win, resolves to '76ers'. If Celtics win, resolves to 'Celtics'. Includes postponement (market stays open) and cancellation (50-50 split) clauses. Result determined by final score including overtime.
- Kalshi: Logical contradiction: 'If Philadelphia wins...then resolves to Yes' AND 'If Boston wins...then resolves to Yes.' Both mutually exclusive outcomes map to the same resolution state, violating binary market structure. No cancellation or postponement rules provided.
