Description

This event tracks the performance of three professional golfers competing in the first round of a tournament, focusing on who among them achieves the best result. The outcome depends on the relative standing of the players after the round concludes. Tie scenarios and player withdrawals are accounted for with specific payout adjustments.

Kalshi

The event resolves based on which of the three golfers—Rory McIlroy, Brooks Koepka, or Robert MacIntyre—wins their 3-ball matchup in the first round of the 2026 Amgen Irish Open. A player wins the matchup by having the lowest score after the round’s completion. If multiple participants finish tied for the lead, the payout for the 'Yes' outcome is prorated equally among tied participants, calculated as $1 divided by the number of tied participants, rounded down to the nearest cent. The 'No' payout is the remainder of the dollar after subtracting the prorated 'Yes' payout. If any golfer withdraws before teeing off, all markets resolve at fair market value.
