The outcome is determined by which player wins the set according to standard tennis scoring rules.

Resolution typically occurs within hours of the match completion, as soon as the result is confirmed and published by official tournament records or major sports data providers.

Several factors could shift odds before the match begins or during play. Pre-match developments include injury reports, recent tournament performance, head-to-head records, and court surface suitability for each player's style. On-court momentum—breaks of serve, set momentum, and visible fatigue—can trigger sharp repricing once the set is underway. Weather conditions, crowd energy, and unexpected tactical adjustments may also influence trader sentiment. Major upsets or dominant performances by either player typically produce the largest price swings as the market recalibrates its probability estimate in real time.
