Trade & Get Up to $100
OG Promo Code Offer: Up to $100 in Bonuses for the NBA Finals
The OG promo code offer requires no code at all — simply sign up for a new account and start trading to unlock rewards. New users can earn up to $100 in total trading bonuses based on cumulative trade and settle volume, making Game 2 of the NBA Finals an ideal event to get started. The bonus structure works in tiers, so the more you trade and settle, the more you earn.
Here is how the bonus milestones break down:
- 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 on whether the Knicks will win Game 2 and your position settles correctly, your payout arrives quickly and counts toward your volume total. If the trade does not go your way, you can sell your contracts early at the current market price to manage your position before the game ends. Either way, your settled volume counts toward unlocking the next bonus tier.
There are a few key terms to keep in mind. This 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. You must be physically located in a legal OG state to participate.
The offer expires on Dec. 31, 2026. For more options, check out the best prediction market promos currently available.
