The Western Conference finals are heating up, and Friday, May 22, is a great time to join one of the best prediction market apps available. Enter Polymarket promo code COVERS when you sign up to unlock a $50 bonus and start trading on Spurs vs. Thunder Game 3, with San Antonio and Oklahoma City each battling injuries as the series sits knotted at one game apiece.
Polymarket Promo Code Offer: $50 Bonus for Spurs vs. Thunder Game 3
The Polymarket promo code COVERS unlocks a $50 welcome bonus for new users in most U.S. states, with the exception of Nevada. To activate the offer, you must deposit a minimum of $20 after completing registration. Unlike traditional sportsbook promotions, this is a prediction market platform where you trade on outcomes rather than place standard wagers.
With Game 3 tipping off Friday in San Antonio, there is plenty to trade on. De'Aaron Fox and rookie Dylan Harper are both listed as questionable for the Spurs, while Thunder forward Jalen Williams is also questionable after leaving Game 2 early with hamstring tightness. If you trade on the Thunder to win Game 3 and Oklahoma City pulls it off without Williams, your position pays out accordingly. If the Spurs rally behind Stephon Castle, who averaged 21 points and 9.5 assists through the first two games, and you traded on San Antonio, you would collect on that outcome instead.
Here are the key terms and conditions to keep in mind before claiming the offer:
- Available in all U.S. states except Nevada
- Minimum deposit of $20 required to activate the bonus
- Must register with promo code COVERS to be eligible
- Proof of ID required, including a photo of a driver's license or passport and a selfie
- You must be physically located in an eligible state at the time of registration
