Trade & Get Up to $100
OG Promo Code Offer: Earn Up to $100 in Bonuses
The OG promo code welcome offer rewards new users with trading bonuses as they reach cumulative trade and settle volume milestones. No code is required to activate the offer, and the bonus structure is tiered, meaning your first trade on South Korea vs Czechia gets the ball rolling toward the full $100 total.
- Trade and settle $10 to receive a $10 bonus
- Trade and settle $100 to receive an additional $15 bonus
- Trade and settle $250 to receive an additional $25 bonus
- Trade and settle $500 to receive an additional $50 bonus
For example, if you trade $10 on South Korea to win their Group A opener and the result goes your way, you pocket your winnings and unlock that first $10 bonus. If the match ends in a draw as predicted and your position does not settle in your favor, you can still close your position early at the current market price to manage your outcome. Either way, that first settled trade counts toward your cumulative volume total.
The offer is available to new users in all U.S. states except New York and Arizona. Users in Illinois, Massachusetts, Maryland, Michigan, New Jersey, Nevada, and Ohio may claim the bonus but cannot apply it to sports trading. You must be physically located in a legal OG state to participate, and the offer expires Dec. 31, 2026.
