How the Polymarket Promo Code Works for World Series Game 4

New users can activate the Polymarket promo code COVERS during sign-up to unlock the $25 trading bonus. The code must be entered before completing registration, and it cannot be applied retroactively once an account is created.

Here is how the offer plays out when tied to a real event like World Series Game 4 between the Brewers and Rays. If a trader deposits $10, enters the code, and takes a position on the outcome of Tuesday's game that resolves in their favor, the profit becomes withdrawable cash once the 1x playthrough requirement is met. If the trade does not resolve in their favor, the $25 bonus funds remain available to use on another eligible market, such as Pistons-Knicks or Trailblazers-Lakers.

Key terms to know before claiming the offer:

  • Available in every U.S. state except Nevada
  • Requires a minimum deposit of $10
  • ID verification is required during sign-up
  • Bonus funds carry a 1x playthrough requirement
  • Offer applies to new sign-ups only and terms may change without notice

Returning users who want to invite others can later use their own Polymarket referral code to earn additional bonuses. Anyone comparing options across the market should also review the best prediction market promos before deciding where to sign up.
