Marta Kostyuk and Ekaterina Alexandrova will compete in the 2026 US Open Women Singles Round Of 32, with observers anticipating the match's duration through game counts. The players' strategic approaches and endurance will be key factors in determining how many games are played.
Markets resolve if the total completed games exceed thresholds of 15.5, 20.5, or 25.5. If the match is canceled before play due to injury, walkover, forfeiture, or other reasons, markets resolve to a fair price. Postponements or delays keep markets open until the rescheduled match finishes within two weeks. Retirements permit resolution based on completed play; unresolved markets settle at Fair Market Price as determined by the Exchange.
