Description

Kalshi

All markets resolve based on the total number of completed games in the full match exceeding specified thresholds (16.5, 21.5, or 26.5). If the match does not occur due to injury, walkover, forfeiture, or cancellation before play begins, markets resolve to a fair price. Postponements or delays keep markets open until the rescheduled match concludes within two weeks. In case of retirement, markets that can be settled based on completed play resolve accordingly, while others resolve to Fair Market Price at the Exchange's discretion.
