Spurs vs. Knicks Game 3: How the OG Promo Code Unlocks Up to $100 in Bonuses
The OG promo code offer requires no code at all. Simply sign up as a new user, and you are eligible. New users can earn up to $100 in total trading bonuses based on cumulative trade and settlement volume, unlocked in stages as you hit key milestones. Here is how the bonus structure breaks 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 3 and your position settles correctly, that volume counts toward your milestone total, and you collect your payout. If your trade does not go your way, say the Spurs pull off a comeback, and you backed New York. You can also close your position early by selling your contracts at the current market price to manage your exposure before the game ends.
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 apply it to sports trading. You must be physically located in a legal OG state to participate. The offer expires Dec. 31, 2026. For more options, check out the best prediction market promos available right now.
