Trade $10 & Get $10
OG Promo Code Offer: Trade $10, Get $10 on MLB and WNBA Markets
The OG promo code page has everything you need to know about this welcome offer, and the good news is that no code is required to claim it. New users simply need to register, verify their identity, and settle at least one qualifying trade worth $10 or more within seven days of KYC approval to become eligible for the $10 reward. Saturday's MLB and WNBA slate gives you a strong starting point for that first trade.
Here are the key terms to keep in mind before you trade:
- No promo code required
- Minimum qualifying trade: $10
- Trade must settle within 7 days of identity verification
- Only trades with implied probabilities below 80% qualify
- Trades placed using reward funds do not count
- Each trade is only counted once it has settled
For example, if you place a $10 trade on the Red Sox-Dodgers market and your prediction is correct, you receive your payout when the market settles and unlock your $10 reward. If your prediction does not land, the trade still counts toward the promotion as long as it meets the eligibility criteria, including the sub-80% probability threshold. Games like Rangers-Astros or Liberty-Mercury offer the kind of competitive markets where probabilities are likely to fall within the qualifying range. You can also exit a position early by selling your contracts at the current market price before settlement.
