How the Polymarket Promo Code Works

The Polymarket promo code offer is straightforward and designed for new traders. You'll need to enter code COVERS when you create your account to unlock the bonus. After registering with your personal information and verifying your identity through a photo ID and selfie, you must make an initial deposit of $10 to activate the welcome offer. Once your deposit is confirmed, Polymarket credits $20 in trading bonus funds to your account, giving you $30 total to trade with on the Reds vs. Cubs game or any other available markets.

Here are the key terms and conditions for this offer:

  • Available in all U.S. states except Nevada
  • You must be physically located in an eligible state to claim
  • Promo code COVERS is required at signup
  • Minimum deposit of $10 is required
  • Photo ID and selfie verification are mandatory

If you trade on the Reds vs. Cubs matchup and your prediction proves correct, your winnings are added to your account balance. If your trade doesn't go as expected, you've only used a portion of your bonus funds rather than your own money. This structure lets you explore prediction trading with confidence.
