Polymarket Promo Code Unlocks $20 Bonus for MLB and WNBA Trading

The Polymarket promo code offer is straightforward: deposit $10, enter code COVERS at registration, and receive a $20 trading bonus. That bonus gives new users added capital to place trades across Wednesday's full MLB board and the three-game WNBA card, covering matchups like Dodgers-Cubs, Cardinals-Yankees, and Storm-Liberty.

Here is a quick look at the key terms attached to this offer:

  • Available in all U.S. states except Nevada
  • You must be physically located in an eligible state
  • Minimum deposit of $10 is required to activate the bonus
  • Proof of ID is required, including a photo of a driver's license or passport and a selfie holding that ID
  • Code COVERS must be entered during registration

The $20 bonus applies to your trading activity, meaning you can put it toward any of the available markets on the platform. If your trade on a game like Dodgers-Cubs wins, you keep the returns. If it does not go your way, the bonus helps cushion the outcome. Polymarket also extends well beyond sports, covering politics, economics, entertainment, and more, which makes the bonus useful across a wide range of markets.
