How the Polymarket Promo Code Works for MLB Wild Card Trading

New users can activate the Polymarket promo code COVERS to receive a $50 trading bonus after making a qualifying deposit. A code is required to trigger this offer, and traders must enter it during registration before placing any trades on Tuesday's Wild Card slate. The bonus is designed for first-time users looking to explore event contracts tied to games like Philadelphia at Atlanta or Boston at New York.

  • Deposit at least $10 to unlock the reward.
  • Available in most U.S. states, excluding Nevada.
  • Requires identity verification with a government-issued ID.
  • Sign-up code must be entered before your first trade.

Consider a trade on the Chicago-Houston Wild Card matchup. If a trader uses part of the bonus to back an outcome tied to that game and the position resolves in their favor, the payout reflects the odds at the time of the trade. If the position does not resolve favorably, the trader's stake is used up, though the account can still hold remaining bonus funds for other markets, such as the Boston-New York or Chicago-San Diego contests.

Existing users can also share a Polymarket referral code with friends to help them access similar rewards. Traders exploring more than one offer before this postseason window closes may want to review best prediction market promos to see how Polymarket's terms compare across the market.
