Why Polymarket is Best Knicks vs. Spurs Prediction Market for NBA Finals
The Spurs are favored in this series after defeating the reigning champion Thunder in seven games. However, the Knicks have a well-rounded team and had a lot of rest heading into Game 1 of the Finals. The biggest question is how the Knicks stingy defense will match up against superstar Victor Wembanyama.
Here's the current Polymarket probabilities for Knicks vs. Spurs Game 1 at the Frost Bank Center in San Antonio tonight:
