Intro

This market tracks whether Rory McIlroy will lead at the end of Round 1 in the 2026 BMW Championship on Kalshi, with the resolution based on official tournament results. Currently, Rory McIlroy leads with a probability of 21.0%, while J.J. Spaun follows at 20.0%. The outcome will be determined by the leader after the first round concludes on September 6, 2026, marking the end of the betting period for this event.

Kalshi

Each market corresponds to a specific golfer, resolving to 'Yes' if that golfer is the sole leader at the end of Round 1 of the 2026 BMW Championship. If multiple participants share the lead, 'Yes' positions pay $1 divided by the number of tied leaders (rounded down to the nearest cent), while 'No' positions pay the complement of that amount (1 minus the 'Yes' payout). The markets are independent, with each golfer’s outcome determined solely by their own standing relative to others after Round 1. Kalshi disclaims any official affiliation with the PGA, and all trademarks remain the property of their respective owners.
