The Polymarket US App serves as an independent software provider and affiliate of Polymarket US and Polymarket Clearing, the CFTC-regulated exchange and clearing organization.
How the Polymarket Promo Code Works for the Seahawks vs. Broncos Game
The Polymarket promo code SIBONUS unlocks a $25 trading bonus when you meet the offer requirements. You must enter code SIBONUS during registration, provide valid ID verification, and make an initial deposit of at least $10 to qualify. Once you complete your first real-money trade on any eligible market, including predictions tied to the Seahawks-Broncos game, your $25 bonus becomes available for trading.
Here are the key terms and conditions for this offer:
- Available in most U.S. states except Nevada

- Code SIBONUS must be entered at registration, not after account creation

If your initial trade doesn't go your way, you still receive the $25 bonus to use on your next trades. The bonus requires a 1x playthrough before any profits become withdrawable as cash.
