What You Can Trade at The Open
Royal Birkdale's markets go well beyond simply picking a winner. Across prediction market apps, you'll typically find:
- Championship winner — Outright contracts on every golfer in the field.
- Top-five / top-10 finish — A lower-variance way to back a contender without needing the outright.
- First-round leader — A Thursday-only market that settles fast.
- Make the cut / miss the cut — 36-hole outcomes that resolve Friday.
- Head-to-head matchups — One golfer vs. another over the round or the tournament.
- Nationality or tour of the winner — Broader props for those reading the bigger picture.
Prices update live, so contracts you buy Thursday morning can be sold back later in the round if the market moves your way, which is a flexibility traditional futures bets don't offer.
How to Get Started Before Round 1
- Click Open Championship prediction market promos link above.
- Tap sign up and enter the listed promo code during registration — codes generally can't be added after the account is created.
- Complete identity verification (standard KYC on every regulated platform).
- Fund your account with a required minimum deposit.
- Place your qualifying trade on PGA odds market to unlock the bonus.
The whole process takes only a few minutes, which matters today when the opening tee times at Birkdale come and go quickly.
