Trade $10 & Get $10
OG Promo Code Offer: Trade $10, Get $10 on Cubs vs. Cardinals
The OG promo code offer requires no code at all, making it one of the more straightforward welcome promotions available on prediction market platforms. New users simply need to register, verify their identity, and complete at least one qualifying trade worth $10 or more within seven days of KYC approval to become eligible for the $10 reward.
Tuesday's Cubs vs. Cardinals matchup at Busch Stadium is a strong candidate for your first qualifying trade. Whether you back the Cubs, who enter as the steadier team with a favorable run differential, or the Cardinals, who have home field and urgency on their side, the game offers a natural starting point for your first settled contract on OG.com.
Here are the key terms to keep in mind before trading:
- No promo code is required to claim the offer
- Your qualifying trade must be worth at least $10
- Only trades with implied probabilities below 80% count toward the promotion
- The promotion expires seven days after account verification
- Only trades that settle within the seven-day window are eligible
- Trades placed using reward funds do not count
For example, if you trade $10 on the Cubs to win Tuesday's game and Chicago pulls it out, your payout will appear in your account once the market settles. If the Cardinals win instead, that trade still counts as your qualifying activity as long as it meets the terms above. You can also exit your position early by selling your contracts at the current market price if you want to lock in a return or limit a potential loss before the game ends.
