Trade $10 & Get $10
OG Promo Code Offer: Trade $10, Get $10 on The Open Championship
The OG promo code offer requires no code at sign-up, making it straightforward for new users to claim. Once your account is verified, you have seven days from KYC approval to place and settle at least one qualifying trade worth $10 or more. The Open Championship at Royal Birkdale is a great starting point for your first trade, with markets available on outright winners, round leaders, and more.
There are a few key terms to keep in mind before you trade:
- Your qualifying trade must be worth at least $10.
- Only trades with implied probabilities below 80% count toward the promotion.
- Trades placed using reward funds do not qualify.
- The promotion expires seven days after account verification.
- Only trades that settle within the seven-day window are eligible.
For example, if you trade on Scottie Scheffler to win The Open and your prediction is correct, you will receive your payout once the market settles and become eligible for the $10 reward. If your prediction does not pan out and Rory McIlroy lifts the Claret Jug instead, the trade still counts toward the promotion as long as it meets the eligibility requirements. You can also exit a position early by selling your contracts at the current market price to lock in gains or limit losses before the tournament concludes.
