The Thunder vs. Spurs prediction markets headline the final game of NBA opening night Tuesday, with San Antonio hosting Oklahoma City at 9:30 p.m. ET on NBC and Peacock. Eligible new users can also claim the Polymarket promo code ACTION, which provides a $25 trading bonus after a $10 deposit.
San Antonio eliminated Oklahoma City in seven games in last season's Western Conference Finals, and the rematch begins at Frost Bank Center with the market pricing the teams nearly even.
My favorite NBA pick from the list of Thunder vs. Spurs prediction markets is Spurs to win at 51¢, which returns about $196 on a $100 position if San Antonio wins. The price dropped from around 56¢ Monday after Chet Holmgren was left off the injury report, but I still prefer the Spurs at home.

The moneyline is essentially a coin flip, with San Antonio at 51¢ and Oklahoma City at 50¢. The spread market gives the Thunder a slightly better chance of staying within 2.5 points, while the total centers around 231.5.
Thunder vs. Spurs Prediction
San Antonio had Oklahoma City's number last season, winning four of five regular-season meetings before eliminating the Thunder in seven games in the Western Conference Finals. The Spurs also return most of their core around Victor Wembanyama, De'Aaron Fox, Stephon Castle and Dylan Harper.
- Thunder vs. Spurs prediction: Spurs to win at 51¢ ($100 returns about $196)
Oklahoma City still has Shai Gilgeous-Alexander and Jalen Williams, but Lu Dort, Isaiah Joe and Aaron Wiggins are gone. Chet Holmgren is expected back after missing the preseason with a quad injury, though his first meaningful game since spring comes against Wembanyama.
Home court, continuity and OKC's offseason losses give San Antonio the edge for me.
At nearly a coin-flip price, I prefer the moneyline over Spurs -2.5. My projected script also leans Under 231.5, but San Antonio outright is the cleaner position.

Conclusion
San Antonio is my preferred side in the Thunder vs. Spurs prediction markets at 51¢.
The Spurs have home court, more continuity and a recent matchup advantage after eliminating Oklahoma City last spring. Holmgren's return strengthens the Thunder, but Dort's absence and the loss of several rotation shooters create new questions around Gilgeous-Alexander.
