The 2025 NBA Cup, the third edition of the league's in-season tournament that started in 2023, begins Friday night with group stage play. The Boston Celtics, reigning NBA champions, aim to improve on their 2024 performance when they failed to advance past the group stage.
The Celtics are in Group B alongside the Philadelphia 76ers, Detroit Pistons, Orlando Magic, and Brooklyn Nets. They kicked off the tournament with a narrow 109-108 victory over the 76ers.
All 30 NBA teams compete in group play, divided into six groups of five teams based on their conference. Each team plays four group games—two at home and two on the road—facing each group opponent once.
Eight teams qualify for the single-elimination knockout stage: the six group winners plus a wild card from each conference, which goes to the second-place team with the best overall record.
