If the 2026 year-end rankings are not published, are canceled, or a year-end No. 1 has not been determined by January 14 2027, 11:59 PM ET, this market will resolve to "Other." If multiple players are tied and officially recognized as co-No. 1, this market will resolve in favor of the player whose listed name comes first alphabetically. The resolution source for this market will be the official ATP year-end rankings as published by the ATP Tour (atptour.com); however, a consensus of credible reporting may also be used.
