The market resolves based on the winner of the third set in the specified professional tennis match. If the match does not commence due to injury, walkover, forfeiture, or cancellation before any play, the market settles at a fair price.

If a player retires during the match, markets that can be determined from completed play will resolve accordingly, while unresolved markets settle at a fair market price determined by the Exchange. Kalshi disclaims any official affiliation with the governing league, and all trademarks remain property of their respective owners.

Key signals that could shift this market include player injuries, recent form in earlier sets, weather or court conditions affecting performance, and any notable strategic adjustments made by coaches or players. Significant momentum swings during the match or last-minute changes in player availability may also cause rapid shifts in trader sentiment and pricing on Kalshi as the event approaches.
