Trade & Get Up to $100
OG Promo Code Offer: Up to $100 in Bonuses for Knicks vs. Cavaliers
The OG promo code offer requires no code at all — simply sign up as a new user and you are eligible to earn up to $100 in trading bonuses based on your cumulative trade and settle volume. No single large deposit is required; instead, bonuses are unlocked in tiers as you continue trading on the platform. 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 1 against the Cavaliers and your position settles correctly, that volume counts toward your bonus milestones and you receive a payout. If your prediction does not pan out and the Cavaliers pull off the upset, your settled 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 apply it to sports trading specifically. You must be physically located in a legal OG state to participate, and the offer expires Dec. 31, 2026.
