Argentina will play Spain in the final of the 2026 FIFA World Cup on July 19, 2026. The match takes place at the New York/New Jersey Stadium in New Jersey, starting at 3:00 PM Eastern Time (9:00 PM in Madrid, 4:00 PM in Buenos Aires). It is the 104th and final game of the tournament. Argentina are the current World Cup champions and also the champions of South America. Spain are the champions of Europe (FIFA).

Lionel Messi is now 39 years old. He has scored eight goals in seven games at this World Cup. Kylian Mbappé scored more — he is the tournament's top scorer, two goals ahead of Messi (BBC Sport).

Argentina's path to the final was not always smooth. In a group-stage game against Egypt, Argentina was losing by two goals before coming back to draw 2–2. Messi was seen crying after that match (Reuters). In another group-stage game against Cape Verde, Messi ran 6.5 kilometers in the first 90 minutes. About 62% of that distance was just walking. This fits his style in recent years: he saves his energy and then makes short, fast bursts at key moments (BBC Sport).

Messi now holds several records at the World Cup that no other player has matched. He has been captain in 19 World Cup matches — more than anyone else. Rafa Márquez had 17, and Diego Maradona had 16 (FIFA). He is also the all-time top scorer in South American World Cup qualifying, with 34 goals. (Qualifying is the set of matches teams play to earn a place at the World Cup.) CONMEBOL is the organization that runs football in South America (FIFA). He is the only player who has scored at World Cups in his teens, his 20s, and his 30s (FIFA). Of his 21 World Cup goals, 15 have come since he turned 35 (BBC Sport).

Before the 2022 World Cup final in Qatar, Messi suggested that it would be his last World Cup. He won that final. The suggestion turned out to be wrong. He has now done the same thing again — leaving open the question of whether this final will truly be his last.

Argentina's manager, Lionel Scaloni, called Messi "the best footballer the world has ever seen." He said he has not asked Messi whether the 2026 final will be his last game (BBC Sport). Spanish football expert Guillem Balague said he does not think the 2026 final will be Messi's last World Cup appearance (BBC Sport).

One reason this matters is the 2030 World Cup. That tournament will be special because of where it is held. Six countries will share hosting duties: Spain, Portugal, and Morocco as the main hosts, with at least one match each in Argentina, Uruguay, and Paraguay. At least one opening match — to mark 100 years since the first World Cup — will take place in Argentina (BBC Sport).

If Messi plays at the 2030 World Cup, he would be 43. That would make him the oldest outfield player (a player who is not a goalkeeper) ever to appear at a World Cup. Cristiano Ronaldo could also play for Portugal in 2030 and challenge the same record. The two have been rivals for nearly 20 years, and a final meeting at a World Cup would be a dramatic ending to that rivalry (BBC Sport).

Messi currently plays for Inter Miami in Major League Soccer, the top league in the United States (BBC Sport). The league schedule there is less demanding than in Europe's top leagues, which may help him stay fit. Combined with the 2030 tournament's special opening match in Argentina, that gives him a possible path to a fifth World Cup — though it would be physically very hard. Messi won his first World Cup in Qatar in 2022 (BBC Sport). If he wins again on July 19, he would join a very small group of players who have won the trophy in two consecutive tournaments.

The broader context here is that playing this well at a World Cup in your late 30s is almost unheard of. Scoring 15 World Cup goals after age 35 has no obvious comparison in the modern era. The captaincy record, the South American qualifying record, and the scoring across three decades all point to the same thing: the question is no longer whether Messi can play at a World Cup at 39, but whether a fifth tournament at 43 is physically possible. His tears after the Egypt match showed how much pressure each campaign now carries. And the centenary match in Argentina adds meaning beyond sport. The first World Cup was held in Uruguay in 1930. A 100-year anniversary match on Argentine soil would matter to any Argentine player, but especially to one whose career has gone from teenage debut to 39-year-old captain.

Whether the pull of 2030 wins out or the 2026 final is truly the end is, at this point, up to Messi. Scaloni has not asked him. Balague does not believe it. And Messi's own history of retirement hints suggests we should be skeptical.
