How to Claim Your Polymarket Promo Code $50 Bonus

The Polymarket promo code offer is straightforward, but there are a few important details to understand before signing up. New users who register with code COVERS and make a minimum deposit of $20 will unlock a $50 bonus. The offer is available in all U.S. states except Nevada, and you must be physically located in an eligible state at the time of registration.

Here is a breakdown of the key terms and conditions attached to this offer:

  • Available in all U.S. states except Nevada
  • Must enter promo code COVERS at registration
  • Minimum deposit of $20 required to activate the bonus
  • Proof of ID required, including a photo of a driver's license or passport and a selfie holding that ID
  • You must be physically located in an eligible state

Polymarket is not a traditional sportsbook. It is a prediction market platform where users trade on the likelihood of real-world outcomes, including sports, politics, entertainment, economics, and more. For Sunday's action, that means you can trade on markets tied to Game 4 between Victor Wembanyama's Spurs and Shai Gilgeous-Alexander's Thunder, the Vegas Golden Knights hosting the Colorado Avalanche in the NHL's Western Conference Final, or any number of MLB and WNBA outcomes. If your trade on, say, the Thunder winning Game 4 resolves correctly, your position pays out accordingly. If the Spurs hold serve at home and your Thunder position does not resolve in your favor, you lose the value of that trade. The $50 bonus gives new users added cushion as they explore the platform's wide range of markets.
