$20 Polymarket Promo Code Bonus Details

The Polymarket promo code COVERS provides new users with a $20 deposit match bonus. To qualify, you must deposit $20 and enter the code during registration. The bonus applies to trading on various markets, including tonight's sports action across MLB, NBA playoffs, and NHL playoffs.

Key terms include eligibility for new users in authorized jurisdictions, a minimum $20 deposit requirement, and potential wagering requirements before withdrawing winnings. For example, if you trade $20 on whether the Dodgers beat the Rockies, your profits plus the bonus funds become available for additional trading. If your trade loses, you still retain the $20 bonus to use on other markets, such as NBA playoff outcomes or NHL series predictions.

The bonus typically expires within 30 days of activation, and market restrictions may apply to certain events. Compare this offer with other best prediction market promos to maximize your trading potential.
