Understanding the Polymarket Promo Code for Chiefs vs. Seahawks Trading

The Polymarket promo code SIBONUS delivers a straightforward welcome offer: deposit $10 and receive $25 in trading bonus funds. You must enter the code during registration to qualify, and the bonus applies only to eligible U.S. states (all states except Nevada). The offer requires identity verification, including a photo of your driver's license or passport along with a selfie holding that ID.

Here are the key terms and conditions you should know:

Code SIBONUS must be entered at registration and cannot be applied retroactively
Minimum deposit of $10 is required to unlock the bonus
Available in all U.S. states except Nevada
You must be physically located in an eligible state to claim the offer
Identity verification is mandatory before funds are credited
A 1x playthrough requirement applies before you can withdraw profits from bonus trades

Once you meet the playthrough requirement, any profits from your trades on the Chiefs vs. Seahawks game or other markets become yours to withdraw. For example, if you trade $25 of bonus funds on a Chiefs market outcome and your prediction proves correct, your winnings are available for withdrawal after meeting the playthrough terms. Conversely, if your trade doesn't go as expected, you've only used the bonus funds provided by Polymarket.

The offer is available to both web and mobile users (iOS and Android) who register through a qualifying promotional campaign and satisfy all offer terms. No invitation is required to create a Polymarket account, and you can fund your account using debit cards, bank transfers (ACH), Apple Pay, or cryptocurrency options.
