Description

A tennis match's total game count is evaluated against multiple thresholds to determine if play extends beyond specified lengths. Each threshold represents a distinct benchmark for match duration based on completed games.

Kalshi

Multiple outcome thresholds evaluate whether the full match's completed games exceed set numbers (17.5, 22.5, and 27.5). If play halts before starting due to injury, withdrawal, or cancellation, all markets settle at fair prices. Postponements keep markets open until resolution after rescheduling. Player retirements allow settlement for markets with sufficient completed play, while others resolve at fair market prices determined by the exchange.
