How the Polymarket Promo Code Works for Cowboys vs. Packers
The Polymarket promo code SIBONUS unlocks a $25 trading bonus when you meet the offer requirements. You must enter the code during registration, provide valid identification, and make an initial deposit of at least $10 to qualify. Once you complete your first real-money trade on any eligible market, including the Cowboys vs. Packers game, your bonus funds become available.

- Available in all U.S. states except Nevada

- Minimum deposit of $10 to activate the bonus
- Bonus applies to trades on any eligible market, including sports events like Cowboys vs. Packers
