How the Polymarket Promo Code Works for NFL Week 1

The Polymarket promo code SIBONUS delivers $50 in trading bonus funds when you meet the offer requirements. You must be located in an eligible state (all states except Nevada), provide valid ID during registration, and make an initial deposit of at least $10 to activate the bonus. Once you complete your first real-money trade on any eligible market, your $50 bonus becomes available for trading.

Here are the key terms and conditions you should know:

Code SIBONUS is required at registration to unlock the offer
Available in all U.S. states except Nevada
Minimum deposit of $10 required to qualify
You must complete at least one real-money trade to claim the bonus
A 1x playthrough requirement applies to the bonus before you can withdraw profits
Valid ID and proof of residency are required during sign-up

When you trade on NFL Week 1 markets, your $50 bonus applies alongside your deposited funds. If you place a trade on a market predicting an outcome for the San Francisco versus Los Angeles matchup or any other Week 1 game and your prediction proves correct, your winnings are yours to keep. If your trade doesn't go your way, you've used your bonus funds on a real market without additional cost to your deposit.
