Once the event concludes and the result is publicly available, the market will settle accordingly, paying out shares of the winning outcome at full value and expiring shares of the losing outcome at zero.

Several factors could shift odds before the match takes place. Recent player form, head-to-head records, and ranking changes can influence trader sentiment. Injury announcements or withdrawal news would trigger sharp repricing. Court surface conditions, weather forecasts, and tournament draw updates may also sway expectations. Media coverage highlighting one player's momentum or weakness could prompt renewed trading activity. As the match date approaches, any official updates from the ITF or player statements could cause the market to adjust its implied probabilities.
