Polymarket Promo Code Offer: Claim $20 for Celtics vs. 76ers Game 5

The Polymarket promo code COVERS unlocks a Deposit $20, Get $20 Trading Bonus for new users. Unlike a traditional sportsbook welcome offer, Polymarket is a prediction market platform where you trade event contracts based on real-world outcomes. To claim this offer, you must deposit a minimum of $20 into your new account. Once your deposit is confirmed and a qualifying trade is placed, the $20 bonus will be credited to your account.

With Game 5 on the line, you could trade on whether the Celtics close out the series or the 76ers force a Game 6. If your trade resolves in your favor, any winnings beyond the bonus are yours to keep. If your trade does not go your way, the bonus funds can still be used to place additional trades, subject to the platform's terms. Here are some key conditions to keep in mind:

  • Eligibility: New users only who meet the legal age requirement in an authorized jurisdiction
  • Minimum deposit: $20 required to unlock the bonus
  • Qualifying trade: A real-money trade must be placed before bonus funds are credited
  • Wagering requirements: A 1x playthrough on the bonus amount is typically required before withdrawal
  • Market restrictions: Some markets or events may be excluded from the offer
  • Expiry: Bonus funds generally expire within seven to 30 days if unused

This offer is available on the Polymarket mobile app only. Desktop users who follow the sign-up link will be directed to join a waitlist instead. For a full breakdown of available offers, check out the best prediction market promos compared in one place.
