This market resolves around Jul 22, 2026, once the match concludes and the result is verifiable from credible public sources.

Resolution occurs after the tournament organizers and relevant tennis authorities confirm the final score. Traders should monitor the official ITF schedule and any updates from the venue to anticipate the exact resolution timing.
Several factors may shift trader sentiment before resolution. Recent form and head-to-head records between the two players often drive early trading. Injury announcements or withdrawal news can trigger sharp repricing.
