How the Polymarket Promo Code Works for Week 8 Trading

The Polymarket promo code SIBONUS requires you to deposit a minimum of $10 to qualify for the $25 trading bonus. Once you meet this requirement and complete your first real-money trade, your bonus funds become available for additional trades on any eligible market, including the Week 8 events taking place Friday night.

  • Available in all U.S. states except Nevada
  • Must provide valid ID and selfie verification
