No OG promo code is needed to get started with one of the best prediction market apps available right now.

Trade $10 & Get $10
OG Promo Code Offer: Trade $10, Get $10 on MLB and WNBA
The OG promo code offer requires no code at all, making the sign-up process straightforward for new users. Once your account is verified through the identity verification process, you have seven days to place and settle at least one qualifying trade worth $10 or more. Monday's slate, which includes marquee MLB matchups like Dodgers-Cubs at Wrigley and Blue Jays-Astros, along with WNBA games like Aces-Dream, gives you plenty of options to place that first trade.
There are a few key terms to keep in mind before you get started:
- Your qualifying trade must be worth at least $10.
- Only trades with implied probabilities below 80% count toward the promotion.
- Trades must settle within seven days of your KYC (identity verification) approval.
- Trades placed using reward funds do not count toward the promotion.
For example, if you trade $10 on whether the Dodgers will win at Wrigley Field 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 unlocking the $10 reward, provided the trade meets all the terms above. The Aces-Dream matchup is another strong candidate, as that game carries enough competitive uncertainty to fall below the 80% probability threshold. Keep in mind that this $10 reward represents the value unlocked from your first qualifying trade, and the full promotional window extends seven days from verification.
