Favorites Spain and France head into the 2026 World Cup with strong recent international form and squad depth that underpin the 74% implied probability for an unbeaten champion. Spain’s attacking options remain potent even with Lamine Yamal managing a hamstring recovery ahead of the June 15 opener, while France benefits from elite defensive organization despite William Saliba’s doubtful status. The expanded 48-team format increases total matches, yet historical patterns show top sides often secure the trophy without defeat when avoiding major upsets in knockout rounds. Recent roster confirmations and injury updates have not materially shifted sentiment, reflecting traders’ assessment that the pre-tournament frontrunners hold clear advantages in navigating group stage and beyond.
