Polymarket Promo Code Details for Duke vs St. John's
The Polymarket promo code COVERS requires a $20 deposit to unlock the full welcome bonus, which differs from traditional sportsbook offers. This promotion is available in all states except Nevada, and new users must provide valid identification during registration. The bonus activates immediately after your qualifying deposit, giving you extra funds to trade on Duke's championship odds or St. John's upset potential.
Key terms include:
- Must be physically located in an eligible state
- Photo ID verification required during signup
- Minimum $20 deposit triggers the bonus
- Available for first-time users only
For example, if you predict Duke covers the spread and they win by the required margin, your successful trade pays out based on market odds.
