Oklahoma City Thunder lead trader consensus at 48.5% implied probability for the NBA Western Conference championship, bolstered by their league-best 57-16 record atop the standings, first playoff clinch, and a 12-game win streak that has maintained their top position all season. San Antonio Spurs follow at 22.3%, fueled by a scorching 22-2 run over their last 24 games and NBA-best 21-2 mark since February, positioning Victor Wembanyama's squad as a legitimate threat for the No. 1 seed with home-court advantage in playoffs. Denver Nuggets linger at 11.0% amid a middling 46-28 standing and injury concerns like Peyton Watson's hamstring issue, while Lakers hold 5.7% on solid 47-26 form but face a steep climb; recent momentum and schedule strength underscore the top duo's edge as the regular season nears its April close.
