With four games remaining in the 2025-26 regular season, nine teams have officially clinched playoff berths: the Detroit Pistons, Boston Celtics, New York Knicks, and Cleveland Cavaliers in the East, plus the Oklahoma City Thunder, San Antonio Spurs, Denver Nuggets, Los Angeles Lakers, and Houston Rockets in the West.

The Thunder are on the brink of securing the league's No. 1 overall seed after their dominant 123-87 win over the Lakers. OKC and San Antonio are locked into the top two seeds out West, while the Nuggets recently jumped the Lakers for the No. 3 spot. In the East, the Pistons, Celtics, Knicks, and Cavs are all in, with seeding still to be determined in the final days.

The SoFi Play-In Tournament begins April 14, with the regular season wrapping up April 12. Phoenix and Miami are both locked into the Play-In after losses on Tuesday. The final week promises drama around the margins — seeding battles, rest decisions, and teams jockeying for favorable first-round matchups.
