PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue:

Polymarket provides comprehensive, detailed resolution rules for 40 distinct markets covering moneyline, spreads, player props, and over/unders with explicit thresholds and edge-case handling. Kalshi provides only a single binary market with no threshold specification, scope definition, or edge-case rules, making it fundamentally unresolvable as written.

Hero Tip:

Do not trade the Kalshi market as currently specified. The market states 'If Boston wins...then resolves to Yes' AND 'If Memphis wins...then resolves to Yes,' which is logically impossible—both outcomes cannot resolve to Yes. Clarification from Kalshi is required before settlement. Polymarket markets are fully resolvable and detailed.

Critical Divergence Points:

  • Polymarket: Outlier: Provides 40 distinct, granular markets with explicit resolution thresholds, scope definitions, and comprehensive edge-case handling. Moneyline resolves based on final score including overtime; spreads specify exact point margins (e.g., 'Celtics win by 15 or more points'); player props define threshold boundaries (e.g., 'more than 25.5 points'); over/unders specify exact combined-score thresholds (e.g., '228 or more points'); first-half markets reference halftime score only; all markets include postponement and cancellation rules (resolve 50-50 if canceled with no make-up). Resolution source is official NBA.com box score. Example: 'This market will resolve to Yes if Jaylen Brown scores more than 25.5 points during the game. This market will resolve to No if Jaylen Brown scores 25.5 points or fewer during the game.'
  • Kalshi: Outlier: Provides a single binary market with a logical contradiction and no resolution detail. The market states 'If Boston wins the Boston at Memphis professional basketball game originally scheduled for Mar 20, 2026, then the market resolves to Yes' AND 'If Memphis wins the Boston at Memphis professional basketball game originally scheduled for Mar 20, 2026, then the market resolves to Yes.' This means both possible outcomes resolve to Yes, which is logically impossible and makes the market unresolvable. No threshold, scope, overtime rule, postponement clause, or cancellation rule is specified.
