This market will resolve in favor of the player that finishes the 2026-27 NBA regular season with the highest Player Efficiency Rating (PER) among qualified players. If the leader is not a listed player, the "Other" market will resolve to "Yes". Player Efficiency Rating (PER) is the per-minute productivity rating developed by John Hollinger, as calculated and published for the 2026-27 NBA regular season by Basketball-Reference.com. To qualify, a player must appear in at least 58 regular-season games. Only 2026-27 NBA regular-season games count. NBA Cup group-play and knockout games other than the NBA Cup Championship game are regular-season games and count. Statistics from the preseason, the NBA Cup Championship game, the Play-In Tournament, the playoffs and the All-Star Game are excluded. If a player plays for more than one team during the season, his statistics from all teams are combined. In the event of a tie for the highest PER (to one decimal place as published), this market will resolve in favor of the tied player with more Win Shares during the 2026-27 NBA regular season, as published by Basketball-Reference.com. If a tie still persists, each tied player's market will resolve to "No" and the "Other" market will resolve to "Yes". If the 2026-27 NBA regular season concludes early, is shortened, or is truncated for any reason, the outcome shall be determined using available statistics for completed games, with the games-played requirement reduced to 70 percent of the games each player's team completed, rounded up. If the 2026-27 NBA regular season is cancelled, postponed after April 25, 2027, 11:59 PM ET, or it is unclear which qualified player led the NBA in PER within that timeframe, each listed player's market will resolve to "No" and the "Other" market will resolve to "Yes". The resolution source for this market will be Basketball-Reference.com (https://www.basketball-reference.com/); however, if Basketball-Reference.com is unavailable, a consensus of credible statistical sources that publish PER by the same formula, such as ESPN, may be used.
