PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi market contains a logical contradiction where both possible game outcomes (UMass Lowell win or UMBC win) are mapped to the same resolution state (Yes), making the market fundamentally unresolvable and creating a data integrity failure.Hero tip: This is a critical flaw. The Kalshi market as written cannot distinguish between the two teams winning. Before trading, contact Kalshi support to confirm whether the second condition should resolve to No instead of Yes. Polymarket's winner-take-all structure is logically sound and should be your reference market.

Critical divergence points:

  • Polymarket: Clean winner-take-all binary: UMass Lowell win resolves to 'Massachusetts-Lowell River Hawks', UMBC win resolves to 'UMBC Retrievers'. Includes postponement (market stays open) and cancellation (50-50 split) provisions. Resolution based on final score including overtime.
  • Kalshi: Defective binary structure: Both UMass Lowell win AND UMBC win are stated to resolve to Yes. This creates a logical impossibility where no outcome can resolve to No, making the market unresolvable as currently written.
