How Do Polymarket Markets Work?
Polymarket is built around prediction market trading rather than traditional sportsbook betting. Instead of locking into fixed odds, users buy and sell shares connected to real-world outcomes across sports, politics, entertainment, and other event categories. Sign up today with the Polymarket referral code ACTION, and make your NBA bets on Spurs vs. Thunder today.
Each market has a “Yes” side and a “No” side, with prices generally moving between 1¢ and $1. Those prices function like implied probability. For example, a “Yes” share trading at 56¢ suggests the market gives that outcome roughly a 56% chance of happening. Correct shares settle at $1, while incorrect shares settle at $0.
The main advantage is flexibility. Users do not have to wait until the event ends to manage a position. If the market moves before tip-off or during live action, traders can sell early to capture profit, limit losses, or rebalance their exposure.
Polymarket has also added more NBA markets during the postseason, including game winners, series outcomes, and player-focused contracts. That makes conference finals matchups like Spurs vs. Thunder especially active for users tracking playoff momentum in real time.

Spurs vs. Thunder Game 2: How To Use Your Bonus Today
Spurs vs. Thunder Game 2 gives prediction market users a fascinating setup after San Antonio stole Game 1 on the road. Wembanyama’s 41-point, 24-rebound performance changed the market conversation immediately, while Oklahoma City now has to respond at home to avoid falling into a 0-2 hole.
Current Polymarket pricing for Spurs vs. Thunder Game 2 may move throughout the day as injury updates, market volume, and pregame sentiment impact prices before the 8:30 p.m. ET tip-off on NBC.
Here are a few ways users can approach the matchup with the Polymarket promo code ACTION:
- Game Winner Market: Use the $50 bonus on either side of the Spurs vs. Thunder Game 2 winner market. Oklahoma City may still carry favorite pricing at home, but San Antonio has already proved it can win in this building.
- Series Market: After the Spurs took Game 1, the series price becomes more interesting. Users can trade on whether San Antonio keeps control or Oklahoma City eventually recovers.
- Player-Related Markets: Wembanyama’s Game 1 dominance should drive attention toward player-focused contracts if available. Shai Gilgeous-Alexander markets may also see increased activity as users price in a Thunder bounce-back.
- In-Game Price Movement: Since Polymarket contracts can be bought and sold before settlement, users can react to momentum swings instead of waiting until the final buzzer.
- Limit Orders: Instead of taking the current market price immediately, users can set a preferred entry point and wait for another trader to match it before or during the game.
