Description
This event group covers the NBA game between the Memphis Grizzlies and Detroit Pistons scheduled for March 13, 2026 at 7:30 PM ET in Detroit. Markets span moneyline, spread, over/under totals (full game and first half), and individual player prop bets (points, rebounds, assists).
PredictionHero - Resolution Divergence Alerts (RDA)
Unified Resolution Criteria (Consistent across platforms)
Both Kalshi and Polymarket use identical resolution logic: official NBA.com final score, overtime inclusion, postponement handling (remain open), cancellation handling (50-50 split), and player inactivity rules (resolve No).
Primary resolution logic:
Official NBA box score published on NBA.comCore resolution logic:
- Moneyline markets resolve to the team with the higher final score (including overtime)
- Spread markets resolve based on final point differential: Pistons win by the stated margin or more resolves to Pistons; otherwise Grizzlies
- Over/under markets resolve based on combined final score: total at or above threshold resolves Over; below threshold resolves Under
- First-half markets resolve based on halftime score only, not final score
- Player prop markets resolve Yes if player exceeds the stated threshold, No if at or below threshold
- Player props resolve No if player is listed inactive or does not take the court
- Ties in spread markets resolve to Grizzlies (non-Pistons outcome)
- Halftime ties in first-half moneyline resolve 50-50
Edge cases & Clarifications:
- Game Postponement: If the game is postponed, all markets remain open until the game is completed. No early resolution occurs.
- Game Cancellation: If the game is canceled entirely with no makeup game scheduled, all markets resolve 50-50 (split evenly between Yes and No outcomes).
- Overtime: All overtime periods are included in final score calculations for moneyline, spread, and over/under markets. First-half markets are unaffected by overtime.
- Player Inactivity: If a player is listed as inactive or does not take the court, all prop markets for that player resolve to No regardless of other circumstances.
- Spread Tie: If the final score results in a tie (e.g., Pistons win by exactly 0 points), spread markets resolve to Grizzlies.
Timing:
Resolution occurs after the official final score is published on NBA.com following game completion (including any overtime). First-half markets resolve at halftime. Player prop markets resolve after the official box score is finalized.Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms.
