The 2026-27 Western Conference #1 seed race centers on a tight contest between the Oklahoma City Thunder and San Antonio Spurs, whose implied probabilities sit within five points of each other. Both clubs return elite cores coming off deep playoff runs, with the Thunder relying on two-time MVP Shai Gilgeous-Alexander, a healthy Jalen Williams, Chet Holmgren, and defensive depth after targeted roster adjustments to manage the apron. The Spurs feature Victor Wembanyama—unanimous Defensive Player of the Year and All-NBA anchor—alongside Dylan Harper, Stephon Castle, and De’Aaron Fox in an experimental three-guard starting group that showed promise in preseason. Analysts project both teams for 56-plus wins, well clear of the rest of the conference, while health, head-to-head results, and internal development will determine the regular-season edge heading into the October 20 opener.
