How the Polymarket Referral Code Works for ALCS Game 6

New users can claim this welcome offer by entering the Polymarket promo code COVERS during registration. A code is required to activate the bonus, and the process involves creating an account, verifying identity, and making a qualifying deposit before placing a trade. The offer is structured around a $10 deposit that unlocks a $25 trading bonus once a real-money trade is completed.

Here are the key terms to know before signing up:

  • Available in all states except Nevada
  • Requires a $10 minimum deposit to activate
  • ID verification is mandatory during registration
  • The bonus comes with a 1x playthrough requirement before withdrawal

For example, a trader using their bonus funds on a market tied to Monday's Guardians vs. Rays Game 6 could see those funds grow if their trade resolves favorably, with profits becoming withdrawable cash once the playthrough requirement is met. If the trade does not resolve in their favor, the bonus funds are simply used up without further out-of-pocket cost beyond the original $10 deposit. New users can also look into the Polymarket referral code program after their first trade to earn additional bonuses by inviting others.
