What Could Shift These Odds Before Match Time

Early injuries, weather delays, or late lineup changes typically move prediction markets.

Set-specific props may shift if pre-match warm-ups reveal a player's serve or return form. News on court conditions or surface preparation could also push set-length markets, as clay, hard, or grass variations change pace and point duration significantly.
