How the Polymarket Promo Code Works for NBA Opening Night

The Polymarket promo code SIBONUS delivers a $25 trading bonus when you meet the signup requirements. This bonus is credited to your account after you complete your first real-money trade on any eligible market, including the NBA Opening Night matchups. Once you've met the 1x playthrough requirement on your bonus funds, any profits you generate from your trades are yours to keep and withdraw as cash.

Here are the key terms and conditions for claiming this offer:

  • The offer is available in all U.S. states except Nevada
  • You must be physically located in an eligible state to claim the bonus

If your trade doesn't win, you've used your bonus funds to participate in the prediction market without additional cost beyond your initial deposit.
