The Eastern Conference semifinals tip off Tuesday with a compelling matchup between the fourth-seeded Cleveland Cavaliers and the top-seeded Detroit Pistons, and there is no better time to join one of the best prediction market apps available. Enter Polymarket promo code COVERS when you register to unlock a $20 welcome bonus on May 6 — deposit $20 to get $20 in trading credit.
With J.B. Bickerstaff facing his former team and both clubs coming off grueling Game 7s, this series is already generating serious buzz, and you can get in on the action with a $20 bonus waiting for new users.
Polymarket Promo Code Offer: Deposit $20, Get $20 for Cavaliers vs. Pistons Game 1
The Polymarket promo code offer is straightforward: new users who deposit $20 receive an additional $20 in trading bonus credit. Unlike traditional sportsbook promotions, this is a prediction market platform where you trade event contracts rather than place standard wagers. The Cavaliers vs. Pistons series offers plenty of markets to explore, from who wins Game 1 to series outcomes and player performance questions.
Here is what you need to know about the terms and conditions tied to this offer:
- Eligibility: Open to new users who meet the legal age requirement and reside in a jurisdiction where Polymarket is authorized to operate.
- Minimum deposit: You must deposit at least $20 to unlock the $20 trading bonus.
- Qualifying trade: You will need to place a real-money trade before bonus funds are credited to your account.
- Wagering requirements: A 1x playthrough requirement means you must trade the full bonus amount once before withdrawing any winnings.
- Market restrictions: Some restrictions may apply to specific markets, so review the terms carefully.
- Expiry: Bonus funds typically expire within seven to 30 days if unused.
For example, if you trade your $20 bonus on the Cavaliers to win Game 1 and they pull off the road upset, your winnings are yours to keep once the playthrough requirement is met. If the Pistons hold serve at home as expected, the bonus trade does not come out of your deposited funds. This offer is available via the Polymarket mobile app only — desktop users who follow the link will be directed to a waitlist.
