How the Polymarket Promo Code Works for Bills vs. Raiders

New users can activate the Polymarket promo code COVERS before kickoff of the Bills vs. Raiders NFL afternoon slate on Sunday. The platform requires a $10 minimum deposit to unlock the $25 trading bonus, and the code must be entered during sign-up since it cannot be applied retroactively. From there, traders can place their first qualifying trade on any eligible market tied to this matchup between Buffalo and Las Vegas.

Here's how the bonus plays out with a trade on this game. Say a trader puts $10 into a market tied to the Bills vs. Raiders outcome and the position settles in their favor. That trader keeps their profit and still has the $25 bonus available to use on future trades once the 1x playthrough requirement is met. If the position settles against them, the $10 stake may be lost, but the $25 bonus funds remain intact to apply toward another market.

  • Available in all states except Nevada
  • Requires identity verification with a photo ID and selfie
  • Minimum deposit of $10 to trigger the bonus
  • Bonus requires a 1x playthrough before withdrawal

Those who sign up can also share their own Polymarket referral code to earn further bonuses from friends. Anyone comparing offers before Sunday's game can review the best prediction market promos to see how this bonus stacks up.

Polymarket traders can find sharp Buffalo vs. Las Vegas picks for this AFC matchup, with experts targeting both the spread and total in a game that projects as a high-scoring affair.

  • Neil Parker backs Buffalo -4.5 at 52.4%, citing Las Vegas's league-worst pass defense allowing the highest offensive success rate and third-highest EPA per play while surrendering 34 points per game over the past three weeks, making it a difficult matchup against Josh Allen and a Bills offense ranked second in DVOA, first in EPA per play, and averaging a league-high 32.8 points per game; a winning contract resolves at $1 each, meaning a contract purchased near 52 cents returns approximately 48 cents in profit, while a losing trade under Polymarket's welcome offer would be covered by $200 in bonus bets on a $10 qualifying wager.
  • Joe Osborne recommends the Over 53.5 at 52.4%, noting Buffalo is 4-1 to the Over with games averaging 61 combined points, Las Vegas has allowed 34 points per game over its last three outings, the Raiders have scored 27 points in both home games, and Buffalo has surrendered at least 29 points in four of five contests; a winning contract near 52 cents returns approximately 48 cents in profit per contract, while a losing trade is protected by $200 in bonus bets on a $10 qualifying wager through Polymarket's welcome offer.
