How the Polymarket Promo Code Works

The Polymarket promo code activates your welcome offer once you complete registration and deposit funds. You'll need to provide identification and personal information during signup, then deposit a minimum of $10 to trigger the bonus. Once claimed, your $20 bonus credit is available for trading across Polymarket's full range of markets.

Key terms and conditions include the following:

  • Available in all U.S. states except Nevada
  • Must be physically located in an eligible state
  • Requires valid photo ID and selfie verification
  • Minimum deposit of $10 required
  • Code COVERS must be entered at signup

For example, if you trade on the Cardinals-Reds doubleheader or any of Monday's evening matchups and your prediction proves correct, your winnings add to your account balance. If a trade doesn't go your way, you've still got your bonus credit to continue trading on other events throughout the night.

Comparing best prediction market promos shows that Polymarket's straightforward bonus structure makes it accessible for new traders.
