Knicks vs Spurs Game 2 Odds: Polymarket Backs San Antonio at 68% Despite the Spurs Trailing 1-0

The NBA Finals stay in San Antonio with the New York Knicks up 1-0 on the Spurs, and Polymarket is leaning hard the other way for Game 2. The board prices San Antonio at 68% to even the series, with Knicks shares sitting down at 32%. The pitch is home court and a Wembanyama bounce-back after his 6-for-21 opener, not the team that actually won Game 1. More than $5 million has traded on the market, and the Spurs' number has stayed pinned near the top since the loss. Tip-off is Friday, June 5 at 8:30 p.m. ET, 5:30 p.m. PT, on ABC.
