Team	Probability
New York Knicks	53.8%
San Antonio Spurs	46.2%

When we dig into the numbers to find the true value, we put a lot of stock in advanced metrics and recent situational context. Throughout the playoffs, the Knicks have maintained an exceptional 16.2 Net Rate—representing estimated points scored minus points allowed per 100 possessions. While the Spurs have also been formidable with a 9.8 Net Rate, they trail New York in overall efficiency. Furthermore, the Knicks dominate the glass, capturing 55.0% of available rebounds compared to San Antonio’s 52.2%.

However, momentum shifts matter in prediction markets. We’ve seen time and time again that a single game can flip a series narrative. This is Game 4 of the 2026 NBA Finals—the first time these franchises have clashed for the championship since 1999. The Knicks currently lead the series 2-1, but the Spurs just snatched Game 3 with a 115-111 victory, effectively snapping New York’s incredible 13-game playoff winning streak. It does stand to reason that San Antonio is playing with renewed confidence, making that 46.2% probability an intriguing longshot prediction for those seeking maximum value.
