The 2026 World Cup will feature an expanded format with 48 teams (up from 32), potentially affecting the number of matches teams play throughout the tournament.

This market will resolve based on the number of games Lionel Messi plays for Argentina at the 2026 FIFA World Cup:

A player is considered to have "played" in a match if they appear on the field at any point during the match, including as a substitute. If Messi is named in the squad but doesn't play in any matches, this counts as 0 games. If Messi is on the bench but doesn’t play on the field, this counts as 0 games. If the 2026 World Cup is canceled or postponed beyond 2026, this market will resolve N/A.
