A professional tennis match will conclude with an official game count that determines the outcome. Both athletes must play through all scheduled sets, and the sum of games played will serve as the exclusive basis for evaluating market results.
Markets resolve depending on whether the total completed games in the full match are above specified thresholds (Over 15.5, Over 20.5, or Over 25.5 games). 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 the event of retirement, markets that can be settled using already-completed play resolve accordingly, while unresolved markets resolve to Fair Market Price as determined solely by the Exchange. The Exchange maintains no official affiliation with the Governing League, and all trademarks remain property of their respective owners.
