Polymarket Promo Code SIBONUS: Zero-Fee $50 Bonus for Week 3 College Football Prediction Markets
This Saturday brings Week 3 College Football action, and it's the perfect time to explore prediction market promos on Polymarket. The Polymarket promo code SIBONUS unlocks a $50 trading bonus when you deposit $10, plus zero trading fees on all college football markets through September 20. This offer is available now and gives you the opportunity to trade on the day's marquee matchups.
How the Polymarket Promo Code Works for Week 3 College Football
The Polymarket promo code SIBONUS requires you to enter the code during registration to claim the welcome offer. You'll need to deposit at least $10 to unlock your $50 trading bonus, which becomes available after you complete your first real-money trade on any eligible market.
Polymarket is waiving all trading fees on college football markets for games played on September 19 and 20. Normally, Polymarket charges taker fees that vary by contract price, typically ranging up to around 50 cents per share. Under this promotion, those fees drop to zero, allowing you to keep your full position value when trading on Week 3 College Football matchups.
Here are the key terms and conditions for claiming this offer:
- Code required: Yes (SIBONUS)
- Available in all states except Nevada
- You must be physically located in an eligible state
- Minimum deposit: $10
- Photo ID verification required (driver's license or passport plus selfie)
- One playthrough requirement on bonus funds before withdrawal
- Zero trading fees apply to all college football markets through September 20
If you trade on the LSU vs. Ole Miss matchup at 7 PM ET and your position gains value, you keep the full profit. If your trade moves against you, your loss reflects only the actual market movement, with no additional fees reducing your position. Once you meet the playthrough requirement, any profits become yours to withdraw as cash.
How to Claim Your Polymarket Promo Code Bonus for Week 3 College Football
