Polymarket Promo Code Details for $20 NCAA Tournament Bonus

The Polymarket promo code COVERS provides new users with a $20 welcome bonus after completing registration and making an initial deposit. Unlike traditional sportsbooks, this prediction market platform allows you to trade on outcomes like which teams advance from tonight's Round 3 games, including the high-stakes matchup between the 1-seed and surging 5-seed that has already upset a higher-ranked opponent.

Key terms for this offer include:

  • Available in all U.S. states except Nevada
  • Must enter promo code COVERS during registration
  • Requires photo ID verification, including a driver's license or passport
  • Minimum $20 deposit required to activate bonus

For example, if you predict the 3-seed known for defensive structure will defeat the 2-seed with an efficient offense, and you're correct, your position increases in value. If wrong, you lose your stake on that particular trade. The platform covers various markets beyond sports, including politics and entertainment. To explore more opportunities, check out the best prediction market promos available.
