How to Use the Polymarket Referral Code for NFL Week 5
New users looking to get started this week will need the Polymarket referral code SIBONUS during sign-up to unlock the platform's welcome offer. The process requires account verification, a minimum deposit of $10, and a completed trade before the $25 trading bonus becomes available. Tampa Bay's visit to Dallas on Thursday night gives new users an opening market to satisfy that first-trade requirement.
- Code SIBONUS must be entered at sign-up, not after registration
- A $10 minimum deposit is required to qualify
- One completed trade on any market, including NFL Week 5 games, activates the bonus
- A 1x playthrough requirement applies before profits can be withdrawn
For example, a trader who places a $20 position on the Tampa Bay at Dallas market and sees that outcome resolve in their favor could withdraw the winnings plus the original stake once the playthrough requirement is met. If that same position does not resolve favorably, only the $20 stake is affected, while the $25 bonus remains separate and tied to account activity rather than that single trade. This Polymarket referral code offer is available alongside other listed best prediction market promos for comparison before signing up.
What Is the Polymarket Referral Code?
The Polymarket referral code is COVERS. Enter it at signup, deposit at least $10, and complete an eligible real-money trade to unlock a $25 trading bonus.
