Diogo Costa leads the closely bunched field for most clean sheets at the 2026 FIFA World Cup, with implied probabilities clustered tightly among keepers from Portugal, Belgium, Morocco, and other sides expected to feature organized defenses through the group stage and beyond. Trader consensus reflects Portugal’s recent qualifying stability and Costa’s established role, while Courtois, Bounou, and similar options gain support from teams with strong backlines and favorable early schedules that could produce shutouts. The tight spread stems from comparable defensive depth across multiple nations, uncertain knockout progression for all contenders, and the fact that clean-sheet totals hinge on variables like match volume, opponent quality, and late roster decisions that keep no single goalkeeper dominant in the wisdom-of-crowds pricing.
