Week 4 College Football brings marquee matchups across the slate, and now is the perfect time to trade on these games with a $50 bonus from Polymarket. The Polymarket promo code SIBONUS unlocks this welcome offer when you deposit $10 and complete your first trade. As of Friday, September 25, this prediction market promo gives you bonus funds to trade on the biggest college football games of the week.

How the Polymarket Promo Code Works for Week 4 College Football

The Polymarket promo code SIBONUS delivers a straightforward welcome offer: deposit $10 and receive $50 in bonus trading funds. You'll use this bonus to trade on Week 4 College Football markets and beyond. The bonus requires a 1x playthrough, meaning once you meet that requirement, any profits you generate belong to you and can be withdrawn as cash.

Polymarket is also running a limited-time promotion on college football trades. On September 19 and 20, the platform waived trading fees on all available college football markets for games played on those dates. This means takers (traders whose orders execute immediately) keep their full profits without standard trading fees that typically range from $1.20 to $1.25 per 100 shares depending on contract price.

Here are the key terms and conditions you should know before claiming this offer:

The Polymarket promo code SIBONUS is available in most U.S. states except Nevada
You must be physically located in an eligible state to claim the offer
A minimum deposit of $10 is required to unlock the $50 bonus
You must provide valid photo ID (driver's license or passport) and a selfie holding that ID during registration
Complete at least one real-money trade on any eligible market to activate your bonus funds
The 1x playthrough requirement must be met before you can withdraw profits

When you trade on Week 4 College Football markets, your bonus funds work like regular trading capital. If you predict correctly on a matchup like Texas at Tennessee at noon ET, your bonus funds grow along with any profits. If a trade doesn't go your way, the bonus funds are used first before any personal deposits.
