This market will resolve according to the player who finishes World No. 1 in the official 2026 WTA year-end singles rankings, as published by the WTA at the conclusion of the 2026 season. 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 WTA year-end singles rankings as published by the WTA (https://www.wtatennis.com/rankings/singles); however, a consensus of credible reporting may also be used.
