How the Polymarket Referral Code Works for Ravens vs. Browns

New users can take advantage of the Polymarket promo code COVERS to unlock a $25 trading bonus tied to a $10 qualifying deposit. This offer is available to eligible users in most states, excluding Nevada, and requires identity verification before funds can be deposited or trades placed. Once registered, the bonus can be applied toward any eligible market, including those tied to Sunday's Ravens vs. Browns game.

Here's how it plays out using the matchup as an example. If a new user places a qualifying trade on a Ravens vs. Browns market and the outcome lands in their favor, any profit generated beyond the 1x playthrough requirement becomes withdrawable cash. If the outcome doesn't go their way, the $25 bonus still applies toward the playthrough requirement, giving users another shot at trading on future markets.

  • Deposit $10 minimum to qualify
  • Enter code COVERS during sign-up
  • Complete ID verification with a valid photo ID and selfie
  • Meet the 1x playthrough requirement before withdrawing profits

Users who stick with the platform can also generate their own Polymarket referral code to earn extra bonuses by inviting friends. For those comparing options before committing, it's worth reviewing the best prediction market promos available right now.

Claim a Ravens vs. Browns prediction on Polymarket at 18.5%

  • Tom Oldfield backs Baltimore to win at 18.5%, noting the Ravens have scored 24-plus points in each of their wins this year and that Mark Andrews has logged six-plus targets in four of his last five outings, making Baltimore a live underdog if the ground game stalls; at a market price near 18.5 cents per contract, a winning trade resolves at $1.00 for an approximate profit of 81.5 cents per contract.
