Check out other prediction market promos available today, but this offer gives you immediate access to trade on the weekend's biggest games.

18+ Only. Restrictions and eligibility requirements apply. Not available in all jurisdictions. Trading is risky. 100% loss can occur. See http://polymarket.com/tos  for more information. The Polymarket US App serves as an independent software provider and affiliate of Polymarket US and Polymarket Clearing, the CFTC-regulated exchange and clearing organization. 

How the Polymarket Promo Code Works for College Football Week 9

The Polymarket promo code SIBONUS delivers a $25 trading bonus when you meet the offer requirements. You must enter the code during registration, provide valid identification, and make a $10 deposit to qualify. Once you complete your first trade on any eligible market, your bonus funds will be credited to your account.

Here are the key terms and conditions you should know:

  • Available in all U.S. states except Nevada
  • You must be physically located in an eligible state when claiming the offer
  • Valid photo ID and a selfie holding that ID are required during registration
  • The $10 minimum deposit must be made to unlock the bonus
  • Your bonus funds become available after you place your first real-money trade
  • You must meet a 1x playthrough requirement before withdrawing profits from bonus trades

For example, if you trade on the Florida versus Georgia matchup at 3:30 PM ET and your prediction wins, your profits are yours to keep after meeting the playthrough requirement. If your trade doesn't go your way, you can use your bonus funds on another College Football Week 9 market like Ohio State at USC at 7:30 PM ET or any other available prediction.

The SIBONUS code must be entered at sign-up and cannot be applied retroactively after your account is created. You no longer need an invitation to join Polymarket, and the previous U.S. waitlist has been removed for eligible users. Mobile users on iOS and Android can claim the same promotion when registering through a qualifying campaign.
