Game 4 of the Eastern Conference semifinals tips off Monday, with the Cleveland Cavaliers hosting the Detroit Pistons looking to even the series at two games apiece. If you want to trade on the outcome, now is the time to sign up using a Polymarket promo code and claim a $20 welcome bonus. Enter code COVERS during registration and deposit $20 to unlock the reward, available as of May 11. The $20 bonus is one of the top offers available across the best prediction market apps, and you can put it to work on $20 in trading bonus funds right away.
Polymarket Promo Code Offer: Deposit $20, Get $20 for Pistons vs Cavaliers Game 4
The Polymarket promo code offer is straightforward: deposit $20 into your new account and receive a $20 trading bonus to use on any available market, including the Pistons vs Cavaliers Game 4 matchup. Unlike traditional sportsbook promotions, this is a prediction market platform where you trade event contracts rather than place standard bets. The bonus is available to new U.S. mobile app users only, and desktop visitors will be directed to a waitlist instead.
Here is what you need to know about the terms and conditions tied to this offer:
- Eligibility: New users only 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 bonus.
- Qualifying trade: A real-money trade must be placed before bonus funds are credited to your account.
- Wagering requirements: A 1x playthrough requirement typically applies, meaning you must trade the full bonus amount once before withdrawing any winnings.
- Market restrictions: Some markets or events may be excluded, so review the terms carefully before trading.
- Expiry: Bonus funds generally expire within seven to 30 days if unused.
For example, if you trade your $20 bonus on Cleveland winning Game 4 and the Cavaliers pull through behind another strong performance from Donovan Mitchell or James Harden, your winnings would be withdrawable once the playthrough requirement is met. If the Pistons bounce back and Cade Cunningham avoids the late-game turnover issues that plagued him in Game 3, your bonus trade would not pay out, but your deposited funds remain in your account.
