Anna Leigh Waters holds an overwhelming 91% implied probability in the 2026 Veolia Arizona Open women’s singles market due to her unmatched dominance on the PPA Tour. The top seed has not lost a singles match in more than two years, compiling dozens of titles and extending her streak with straight-sets victories in recent events. She enters as the clear leader in world pickleball rankings and head-to-head results, routinely overpowering the field with superior consistency, placement, and court coverage. Second seed Kate Fahey, at 9%, represents the primary realistic challenger after reaching multiple finals against Waters, yet she has yet to secure a victory in those matchups. Other contenders such as Kaitlyn Christian, Brooke Buckner, and Sofia Sewing carry underdog potential in a deep draw, but any path to the title would require an injury to Waters or a rare breakthrough performance from the lower seeds.
