PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

Both platforms resolve based on official NPB results for their respective games, with clear win conditions and tie/cancellation handling where applicablePrimary resolution logic: Official NPB announcements

Core resolution logic:

  • Kalshi resolves to Yes if either team wins the August 13, 2026 Lions vs. Fighters game
  • Polymarket resolves to the winning team name for the August 19, 2026 Lions vs. Buffaloes game, with 50-50 resolution for ties or cancellations

Edge cases & clarifications:

  • Game Postponement: Polymarket remains open until completed; Kalshi resolves based on final game outcome
  • Game Cancellation: Polymarket resolves 50-50 if no make-up game; Kalshi would resolve based on cancellation rules (not specified but would follow NPB guidelines)
Timing: Resolution occurs after the official conclusion of each respective game, with Kalshi resolving on or after August 13, 2026 and Polymarket on or after August 19, 2026Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms.
