If you deploy your $50 Polymarket sign-up bonus on the moneyline, your potential return depends entirely on which team you back. A $50 wager on the favored Oklahoma City Thunder (-163) would yield a profit of approximately $30.67 if they hold court at home. Conversely, risking that $50 bonus on the underdog San Antonio Spurs (+136) would result in a larger $68.00 profit should they manage to pull off the road victory.

Looking at the advanced metrics from the 2025 postseason, the underdog Spurs might actually offer the more compelling statistical value. San Antonio enters the matchup boasting an exceptional 11.6 Net Rate, outperforming Oklahoma City’s still-solid 8.6 mark. Additionally, the Spurs have dominated the glass throughout this playoff run. San Antonio has secured 52.8% of available rebounds (Tot REB%), compared to the Thunder, who have hovered slightly below breaking even on the boards at 49.7%. Based on this team efficiency and rebounding advantage, the Spurs have a clear pathway to securing an upset win at Paycom Center.
