As of the coming 2023-24 NBA season, the inaugural In-Season Tournament will take place among all thirty teams with the new NBA Cup up for grabs. Taking place from November to early December, teams will be placed into six five-team groups in which each team will play their four group rivals. The best team from each group (and two wildcards) advances to the next round. Teams are randomly designated based on last season’s regular season standings. All games other than the grand final will count toward each team’s regular season record.
After the group rounds, the remaining eight teams compete in a single elimination bracket with the final game in Las Vegas.
