Week 1 NFL kicks off Wednesday, September 9, and it's the perfect time to explore prediction market promos. The Polymarket promo code SIBONUS unlocks a $50 trading bonus when you deposit $10. This code is required to claim the offer, and you can use your bonus to trade on Week 1 NFL matchups and beyond.

18+ Only. Restrictions and eligibility requirements apply. Not available in all jurisdictions. Trading is risky. 100% loss can occur. See http://polymarket.com/tos  for more information. 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.

Understanding the Polymarket Promo Code for Week 1 NFL Trading

The Polymarket promo code SIBONUS delivers straightforward terms for new traders. You must deposit a minimum of $10 to qualify, and the $50 trading bonus credits to your account once you complete your first trade. The bonus applies to any eligible market on the platform, including Week 1 NFL predictions and beyond.

Here are the key terms and conditions you should know:

  • Available in all U.S. states except Nevada
  • You must be physically located in an eligible state
  • Code SIBONUS is required at registration
  • Photo ID verification is mandatory (driver's license or passport with accompanying selfie)
  • Minimum deposit of $10 to unlock the bonus
  • Bonus requires 1x playthrough before profits become withdrawable
  • Available on iOS and Android mobile apps

For example, if you deposit $10 and trade on the Week 1 NFL matchup between New England and Seattle, your $50 bonus activates once that trade settles. Any winnings from your bonus trades become yours to withdraw after meeting the playthrough requirement. The platform accepts debit cards, bank transfers, Apple Pay, and crypto options for deposits.

Polymarket no longer requires an invitation to join, so eligible U.S. users can register immediately. The platform operates as a CFTC-regulated prediction market, offering trading across sports, politics, finance, crypto, and entertainment events. Your promo code must be entered during the registration process and cannot be applied retroactively after account creation.
