How the Polymarket Promo Code Works for Brewers vs. Rays Game 4

The Polymarket promo code requires entering COVERS at sign-up to unlock a $10-for-$25 trading bonus ahead of Tuesday's Brewers vs. Rays Game 4. A code is required to activate this welcome offer, and it cannot be applied retroactively once an account has already been created.

Several terms apply to the offer, including:

  • Available in all U.S. states except Nevada
  • Requires a minimum deposit of $10
  • Identity verification with a valid photo ID is mandatory
  • Bonus funds carry a 1x playthrough requirement before withdrawal

For example, a trader could use part of the bonus to place a position on whether the Brewers complete the sweep in Game 4. If that trade resolves in the trader's favor, the resulting profit becomes withdrawable cash once the 1x playthrough is satisfied. If the trade does not resolve favorably, the bonus funds used on that position are simply exhausted, just as with any other market trade.

New users can also look into the Polymarket referral code program, which rewards existing users for inviting friends to trade on games like Tuesday's World Series matchup. Those comparing options before signing up can review the best prediction market promos to see how this offer measures up across the industry.
