In-season tournament

The NBA introduced the new NBA In-Season Tournament for the 2023–24 season, with all games except the championship final counting towards the regular-season standings. It was modeled after the WNBA Commissioner's Cup and in-season multi-stage competitions held in European soccer. The tournament was structured as follows:

Six intraconference pools of five (three pools per conference). Tuesdays and Fridays during November featured group games against each of the other teams in their pool (two at home and two on the road). These games still counted as regular season games. The winners of each pool (three teams per conference) and two wild-card teams (one team per conference) advanced to a single-elimination tournament. The semifinals and championship game were played in Las Vegas. Players for the tournament champion each received $500,000. To compensate, the NBA's regular season scheduling formula was modified so only 80 games for each team were initially announced during the offseason. The first two rounds of the in-season tournament would then count as regular-season games 81 and 82. The championship game would then be an extra 83rd game that would not count toward the regular season. Teams that did not qualify for the in-season tournament knockout round, or were eliminated in the quarterfinals, were then scheduled additional games against each other that were eliminated in the same conference (if possible) and rounded to reach 82 games.

The schedule for the in-season tournament was released on August 15, 2023, two days before much of the regular season schedule was released. The semi-finals and championship game were hosted in the T-Mobile Arena in Paradise, Nevada. On December 9, 2023, the Los Angeles Lakers went undefeated in the tournament to win the inaugural NBA Cup title by beating the Indiana Pacers in the championship game. LeBron James won the inaugural Tournament MVP award.
