Polymarket Promo Code SIBONUS: Get Bonus for Panthers vs. Cardinals

The Hall of Fame Game returns Thursday night with the Carolina Panthers and Arizona Cardinals squaring off in Canton. If you're looking to trade on this preseason opener, the $20 bonus from Polymarket promo code SIBONUS gives you extra capital to get started. You'll need to deposit $10 to unlock the offer, and the code is required during registration. This is your chance to trade on young quarterbacks, depth battles, and roster decisions that will shape both teams heading into the 2026 season.

How the Polymarket Promo Code SIBONUS Works for the Panthers-Cardinals Game

The Polymarket promo code SIBONUS delivers a straightforward welcome offer: deposit $10 and receive a $20 trading bonus. This bonus gives you additional funds to trade on prediction markets tied to Thursday's Hall of Fame Game and beyond. The bonus is available in most U.S. states except Nevada, and you must be physically located in an eligible area to claim it.

Here's what you need to know about the offer:

Enter promo code SIBONUS during registration to activate the bonus
Make an initial deposit of $10 to unlock the $20 reward
Provide proof of ID, including a photo of your driver's license or passport and a selfie holding that ID
Available in all states except Nevada
You must be physically located in an eligible state to participate

Once you claim the bonus, you can trade on outcomes related to the Panthers-Cardinals matchup. Will Carson Beck, Arizona's rookie quarterback, show poise in his NFL debut? Can Kenny Pickett manage the game efficiently for Carolina? You might trade on which team wins, which quarterback throws for more yards, or which defense records more sacks. If your prediction proves correct, your winnings are yours to keep. If the market moves against your trade, you'll experience a loss on that position.
