How the Polymarket Promo Code Works for MLB Wild Card Betting

New traders can activate this welcome offer with the Polymarket promo code COVERS, which is required during sign-up to trigger the $50 bonus. The process is straightforward: register an account, verify your identity, deposit at least $10, and place a qualifying trade on Wednesday's MLB Wild Card Series action. This offer is available in most states except Nevada and requires users to be physically located in an eligible jurisdiction.

  • Sign-up code COVERS must be entered during registration
  • A minimum deposit of $10 is required to unlock the bonus
  • Identity verification, including a photo ID and selfie, may be requested
  • Available in all U.S. states except Nevada

Consider a trade placed on the Philadelphia at Atlanta contract, where Atlanta entered Wednesday needing one win to advance. If that market resolves in the trader's favor, the position pays out based on the odds locked in at the time of the trade. If the market resolves against the position, the trade simply expires without value, and the $50 bonus remains separate from that outcome. The same logic applies across the Houston at Chicago, Boston at New York or Chicago at San Diego contracts available the same day.

Users interested in additional ways to unlock funds can also look into the Polymarket referral code option, which offers a separate path to bonus funds. For a broader look at how this offer stacks up, bettors can review the best prediction market promos currently available.
