AI analysis

The prediction market is currently indicating a 1% probability that Brooks Koepka will win The Open Championship, as reflected in the YES price of $0.01. This assessment is based on known facts about Koepka's recent form and past performances at major golf tournaments. Specifically, his recent struggles with injuries and inconsistent play have likely contributed to the low probability assigned by market participants. A significant improvement in his game or a notable absence from other top contenders could potentially increase the YES price, while continued poor performance or strong showings from other golfers might lead to further decreases in the probability of Koepka winning. The market will close on August 2nd, 2026, at 4:00 AM UTC, providing an opportunity for participants to reassess their predictions before the event takes place.
