A match price is a player’s Kalshi price to win the match, read as a probability; set and game lines are separate markets.
The head-to-head counts the meetings Kalshi listed and graded since its match markets began in June 2025. Matches before then, and any Kalshi did not list, are not in it.
Matches carry their tournament and round, not a start time: the exchange’s match times disagree with each other, so none is printed.
