PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi's moneyline market contains a logical contradiction: both possible outcomes (Brown win and Columbia win) are mapped to the same resolution (Yes), making the market fundamentally unresolvable. Polymarket's moneyline, spread, and totals markets are logically sound and mutually consistent.Hero tip: Do not trade the Kalshi moneyline. Polymarket offers three well-structured markets (moneyline, spread, totals) with clear, mutually exclusive resolution paths. All three use final score including overtime as the settlement basis, with 50-50 split only if game is canceled with no makeup.

Critical divergence points:

  • Kalshi: Moneyline market claims both Columbia win and Brown win resolve to Yes. This is a logical impossibility for a binary market. Quote: 'If Columbia wins...resolves to Yes. If Brown wins...resolves to Yes.' No resolution path for No outcome exists.
  • Polymarket: Three distinct markets with clear, mutually exclusive resolution logic: (1) Moneyline resolves to winner name; (2) Spread (-5.5) resolves to Columbia if they win by 6+, else Brown; (3) Totals resolve Over/Under based on combined score thresholds (140.5 or 139.5). All use final score including overtime.
