Cavaliers vs. Knicks Game 1: Trade It With a Polymarket Promo Code

The Polymarket promo code offer gives new users a $50 bonus when they sign up and make an initial deposit of $20. The platform is not a traditional sportsbook -- it is a prediction market where users trade on the likelihood of real-world outcomes, including sports, politics, economics, entertainment, and more. That makes it a unique destination for fans looking to engage with the Cavaliers-Knicks series in a different way.

Here is what you need to know about the terms and conditions before claiming the offer:

  • Available in all U.S. states except Nevada
  • You must be physically located in an eligible state at the time of sign-up
  • A minimum deposit of $20 is required to activate the $50 bonus
  • You must provide proof of ID, including a photo of a driver's license or passport and a selfie holding that ID
  • Code COVERS must be entered during registration

For example, if you trade on the Knicks to win Game 1 and they pull it off behind a big night from Jalen Brunson, your position resolves in your favor. If the Cavaliers upset New York and Donovan Mitchell delivers, your trade resolves against you. Either way, the $50 bonus gives you added value to get started on the platform.
