The San Antonio Spurs and Oklahoma City Thunder lead NBA futures markets for the 2027 champion at 22.5% and 19.5% implied probability, respectively, reflecting their status as the league’s clearest title contenders entering the 2026-27 season. Both teams reached the Western Conference Finals or Finals last year behind Victor Wembanyama’s defensive dominance and Shai Gilgeous-Alexander’s back-to-back MVP form, with deep young cores still improving and minimal roster turnover. The Philadelphia 76ers and New York Knicks sit next at 11.1% and 8.5%, buoyed by Eastern Conference strength and returning cores from recent deep runs. Preseason lineups and training-camp adjustments underscore the tight clustering, as multiple teams feature elite defense, versatile wings, and playoff-tested rotations heading into an October 20 opener that pits the Thunder against the Spurs.
