OG Promo Code Offer: Up to $100 in Bonuses for the US Open at Shinnecock Hills
The OG promo code offer is a tiered trading bonus that rewards new users as they reach cumulative trade-and-settle volume milestones. No promo code is required to unlock it. Simply sign up for a new OG.com account and begin trading to start earning bonuses over time.
The US Open at Shinnecock Hills is a great starting point. You could open your account and place your first trade on a contract tied to the tournament, such as whether Scottie Scheffler will win the championship or whether Rory McIlroy will make the cut. If your prediction is correct, you receive a payout once the contract settles. If it does not go your way, your position closes without a payout, but the volume still counts toward your bonus 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
The offer is available to new users in all US 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.
