Unified Resolution Criteria (Consistent across platforms)

Core resolution logic:

  • Resolve to the player who wins the official NBA Rookie of the Year award for the 2026-27 season
  • In case of a tie, resolve to the player whose listed last name comes first alphabetically
  • If the season is cancelled, postponed after April 30, 2027, or no winner is declared by that time, resolve to "Other"

Edge cases & clarifications:

  • Tie/Co-Winners: If multiple winners are announced, resolve to the player whose listed last name comes first alphabetically
  • Season Cancellation: If the 2026-27 NBA regular season is cancelled, postponed after April 30, 2027, 11:59 PM ET, or there is otherwise no winner declared within that timeframe, resolve to "Other"
Timing: Resolution occurs after the official NBA announcement of the Rookie of the Year award winner, no later than June 2027Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms.
