San Antonio Spurs and Oklahoma City Thunder lead NBA Cup betting at 20% and 19% implied probability as the preseason’s top-ranked teams, with Victor Wembanyama anchoring a deep Spurs roster that reached the prior Finals and the Thunder boasting elite depth around Shai Gilgeous-Alexander after consecutive strong regular seasons. Philadelphia 76ers and Detroit Pistons sit next at 12.5% and 11%, reflecting Eastern Conference improvements and roster continuity, while Boston, New York, and Minnesota hover near 9-7% amid solid but less dominant projections. The tight spread across roughly a dozen clubs stems from balanced Western Conference talent, young cores entering prime years, and the single-elimination format’s inherent variance, where recent form, health, and matchups can quickly shift outcomes in the group stage and knockout rounds.
