The NBA Cup opens with group games on set Cup nights from October 30 to November 27, 2026. Eight teams advance to single-elimination rounds: quarterfinals on December 4 and 5, semifinals at the home of the higher seed, and the championship on December 11 at Hinkle Fieldhouse in Indianapolis. Every Cup game except the championship also counts in the regular-season standings, which is why group nights matter beyond the trophy.
