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 $20 deposit. Unlike traditional sportsbooks, this prediction market platform allows you to trade on tournament outcomes with real-time market pricing that fluctuates based on public sentiment and game developments.

Key terms for this offer include:

  • Available in all U.S. states except Nevada
  • Requires identity verification with photo ID and selfie
  • Minimum $20 deposit required to unlock bonus
  • Must use promo code COVERS during registration

For Saturday's NCAA Tournament Round 4 action, you could trade on whether the top seed advances past their dangerous mid-seed opponent, or predict if the high-powered offense can overcome the disciplined defensive squad. If you trade $10 on a team to win and they advance, your shares become worth $1 each. If they lose, your shares expire worthless. The platform's unique structure means you're trading against other users rather than the house.
