Lionel Messi's inclusion in Argentina's preliminary 55-man roster for the 2026 FIFA World Cup has solidified trader confidence, with the "Yes" outcome holding a commanding 95.5% implied probability. The seven-time Ballon d'Or winner continues delivering elite performances for Inter Miami, shattering MLS milestones while maintaining his trademark vision and creativity on the pitch. Coach Lionel Scaloni has repeatedly deferred the final call to Messi, who has signaled he will assess his fitness day-to-day and contribute meaningfully if selected, echoing his approach ahead of past tournaments. FIFA president Gianni Infantino has publicly urged the star to extend his legacy. While an unforeseen injury remains the primary upset scenario that could alter the outcome before the expanded summer event, current form and historical precedent point to a near-certain participation.
