PredictionHero - Resolution Divergence Alerts (RDA)
Divergence Detected
Issue:
Kalshi's resolution logic states both possible game outcomes (either team winning) resolve to Yes, which is logically impossible and makes the market unresolvable. Polymarket uses standard categorical resolution. The underlying game determination is unified, but the market structures are incompatible.Hero Tip:
Do not trade Kalshi's market as stated—the dual-Yes resolution is a critical specification error that would make every outcome resolve Yes. Confirm with Kalshi support whether this is a typo (should be Yes/No for one team) or a unique market design. Polymarket's categorical structure is standard and resolvable. Only trade Polymarket until Kalshi clarifies.Critical Divergence Points:
- Kalshi: Dual-Yes resolution: Both Milwaukee Admirals winning AND Grand Rapids Griffins winning are stated to resolve to Yes. This creates a logical contradiction where the market cannot distinguish outcomes. Quote: 'If Milwaukee Admirals wins...resolves to Yes' and 'If Grand Rapids Griffins wins...resolves to Yes.'
- Polymarket: Categorical resolution: Winning team's name becomes the resolution value (either 'Grand Rapids Griffins' or 'Milwaukee Admirals'). Includes postponement (market stays open) and cancellation (50-50 split) clauses. Quote: 'If Grand Rapids Griffins win, the market will resolve to Grand Rapids Griffins. If Milwaukee Admirals win, the market will resolve to Milwaukee Admirals.'
