With Knicks vs. 76ers Game 3 tipping off Friday in Philadelphia, there has never been a better time to join one of the best prediction market apps available. Enter Polymarket promo code COVERS when you register to unlock a $20 trading bonus by depositing $20 -- a compelling welcome offer available as of May 8.
New users can claim the $20 bonus and start trading on whether the Knicks can push Philadelphia to the brink or the Sixers can finally get on the board.
Polymarket Promo Code Offer: Deposit $20, Get $20 for Knicks vs. 76ers Game 3
The Polymarket promo code offer is straightforward: new users who deposit $20 receive a $20 trading bonus, giving you extra capital to put to work on Game 3 and beyond. Unlike traditional sportsbook promotions, this is a prediction market platform where you trade event contracts rather than place standard bets. With OG Anunoby listed as questionable and Joel Embiid's status uncertain heading into Friday's game, there is plenty of market movement to track.
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 $20 to unlock the $20 trading bonus.
- Qualifying trades: You will likely need to place a real-money trade before bonus funds are credited to your account.
- Wagering requirements: A playthrough requirement may apply, meaning you must trade the full bonus amount before withdrawing any earnings.
- Market restrictions: Some bonus funds may only apply to specific markets, so review the terms carefully.
- Expiry dates: Bonus funds typically expire within seven to 30 days of being credited, so use them promptly.
For example, if you trade your $20 bonus on the Knicks to win Game 3 and the outcome resolves in your favor, your earnings would be available to withdraw after any applicable requirements are met. If the trade does not resolve in your favor, the bonus funds would not be returned. Note that Polymarket's U.S. app is currently rolling out to mobile users only -- desktop users who click the link will be asked to join a waitlist.
