How the Polymarket Referral Code Works for Rays vs. Guardians Game 4

New users can secure this welcome offer by entering the Polymarket promo code COVERS during sign-up. A code is required to unlock the $25 bonus, and traders must deposit at least $10 before placing a qualifying trade on a market tied to Rays vs. Guardians Game 4 or any other listed event.

  • Available in all U.S. states except Nevada
  • Requires photo ID verification during registration
  • Minimum deposit of $10 to trigger the bonus
  • One completed trade needed to release bonus funds

Consider a trader who takes a position on the outcome of Rays vs. Guardians Game 4. If that market resolves in the trader's favor, the profit is paid out in cash once the 1x playthrough requirement tied to the bonus is met. If the market resolves the other way, the trader still holds access to the $25 bonus funds for future trades, since the bonus itself was already credited upon completing the first qualifying trade.

Existing users looking to bring friends aboard can also share a Polymarket referral code to earn additional rewards. Those weighing multiple platforms before committing can review the best prediction market promos to see how this offer compares.

Jon Metler's Tampa Bay vs. Cleveland picks highlight a Polymarket edge in the ALCS Game 4 matchup between the Rays and Guardians.

  • Jon Metler backs the Cleveland Guardians to win at 51.2%, noting that Cleveland is likely to stack eight left-handed bats against Nick Martinez, whose changeup-heavy approach could be neutralized by disciplined hitters near the top of the order who rarely chase pitches outside the zone, with left-handed batters also getting a longer look at the pitch's spin to help them lay off and force Martinez into the strike zone.
