This market resolves around Jul 13, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The resolution hinges on the official match result—which player wins the contest.

Several factors could shift odds before the match takes place. Announcements about player injuries, withdrawals, or fitness updates often trigger sharp moves.
