Lionel Messi’s inclusion in Argentina’s preliminary 55-man squad for the 2026 FIFA World Cup has anchored trader consensus around a strong yes outcome. The defending champions’ coach Lionel Scaloni continues to emphasize Messi’s fitness as the deciding factor while actively involving the 38-year-old in recent friendlies and long-term preparations, underscoring his value to the squad. Messi has repeatedly voiced his desire to compete if physically ready, and his consistent MLS form with Inter Miami reinforces that narrative. The market’s high implied probability reflects these clear signals from the national team setup, though an unexpected injury or last-minute retirement decision could still alter the picture before the final roster is submitted.
