Trade & Get Up to $100
How the OG Promo Code Unlocks Up to $100 in Bonuses for Playoff Action
The OG promo code offer requires no code at sign-up, making it one of the more straightforward bonuses available right now. New users can earn up to $100 in total trading bonuses by reaching cumulative trade and settle volume milestones on the platform. The bonus structure breaks down as follows:
- 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
With the NBA and NHL playoffs entering a critical stretch as second-round series wind down, there is no shortage of compelling contracts to trade on OG. For example, if you buy a "yes" contract on a team advancing in the NBA playoffs and that team wins, your position settles in your favor and counts toward your cumulative volume total. If your prediction is incorrect and the team is eliminated, your position settles against you, but the volume still counts toward unlocking the next bonus tier.
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 use it for sports trading specifically. You must be physically located in a legal OG state to participate. The offer expires Dec. 31, 2026.
