How the Polymarket Promo Code Works for UFC 331 Trading

The Polymarket promo code SIBONUS delivers a straightforward welcome package for new traders. You must enter the code during registration, deposit at least $10, and complete your first real-money trade on any eligible market to unlock the bonus. Once you meet the 1x playthrough requirement, your profits become yours to withdraw as cash.

For UFC 331 trading specifically, you can place trades on various outcomes and markets available on the platform. If your trade on a UFC 331 market wins, your profits are credited to your account immediately. If a trade doesn't go your way, you've only used your deposited funds, not the bonus itself. The bonus applies to all eligible markets, giving you flexibility in how you deploy your trading capital.

Key terms and conditions for claiming this offer include the following requirements:

Code SIBONUS must be entered at registration
Initial deposit of $10 or more is required
You must complete at least one real-money trade to claim the bonus
The offer is available in most U.S. states except Nevada
You must be physically located in an eligible state
Photo ID verification is required during signup
The 1x playthrough requirement applies before you can withdraw profits
