How the Polymarket Promo Code Works for Texas vs. Tennessee
The Polymarket promo code SIBONUS unlocks a $50 trading bonus when you meet the offer requirements.

Once your account is funded and your first trade is placed, your $50 bonus will be credited and ready to use on additional trades.
The bonus comes with a 1x playthrough requirement, meaning you need to trade the bonus amount once before withdrawing any profits. Any gains you make after meeting this requirement are yours to keep. The zero-fee promotion on college football trades runs through September 20, allowing you to execute trades on the Texas vs. Tennessee game without standard taker fees that typically range from $1.20 to $1.25 per 100 shares depending on contract price.
Key terms and conditions include the following:
- Promo code SIBONUS required at registration
- Minimum $10 deposit to unlock the $50 bonus
- Valid ID and proof of residency required
- Available to eligible U.S. users except Nevada residents
- 1x playthrough requirement on bonus funds
