Trade & Get Up to $100
OG Promo Code Offer: Up to $100 in Bonuses for Spurs vs. Knicks Game 4
The OG promo code offer requires no code at sign-up, making it simple for new users to get started. Once registered, you can earn up to $100 in trading bonuses by reaching cumulative trade and settlement volume milestones on the platform. The bonuses are unlocked in stages, so the more you trade, the more you earn.
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
With the Spurs vs. Knicks Game 4 on the slate, you could trade a "yes" contract on the Knicks winning to take a 3-1 series lead. If New York closes it out, your position settles in your favor, and that volume counts toward your bonus milestones. If the Spurs pull off another upset behind Victor Wembanyama, you can sell your contracts early at the current market price to manage your position before the game ends.
Key terms and conditions to keep in mind include the following:
- Available to new users in all U.S. states except New York and Arizona
- Users in IL, MA, MD, MI, NJ, NV, and OH may claim the bonus, but cannot use it for sports trading
- You must be physically located in a legal OG state to claim this offer
- The offer expires Dec. 31, 2026
