Trade $10 & Get $10
OG Promo Code Offer: Trade $10, Get $10 on MLB and WNBA
The OG promo code offer is straightforward: trade $10 and earn a $10 reward, with no code required to unlock it. After verifying your account and completing the identity verification process, you have seven days from KYC approval to place and settle at least one qualifying trade worth $10 or more. Friday's slate gives you plenty of options to get started, from the Yankees-Cubs afternoon game at Wrigley Field to the Red Sox-Dodgers headliner on the West Coast, plus WNBA action featuring Wings-Mystics and Storm-Dream.
Here is a closer look at the key terms to keep in mind:
- No promo code required at sign-up
- Minimum qualifying trade: $10
- Only trades with implied probabilities below 80% count
- Trades must settle within 7 days of KYC approval
- Trades placed using reward funds do not qualify
- Offer expires 7 days after account verification
For example, if you trade $10 on the Red Sox-Dodgers market and your prediction is correct, you receive your payout once the market settles. If your prediction does not land, your qualifying trade still counts toward the promotion as long as it meets the terms above. Either way, completing that first $10 trade on Friday's MLB or WNBA slate puts you in position to earn the $10 reward.
