Predicting the FIFA World Cup winner is difficult. However, based on the record, South America has much potential to be the next champion. Brazil is the most successful World Cup squad, and both Argentina and Uruguay also won the title.

A South American team's chances depend on its players, team dynamics, coaching, preparation, and success in qualification and the tournament. Strong teams from Europe have also produced several recent champions.

The reasons why Brazil and Argentina could win the next worldcup are the following:

Historical Success: Both nations have strong tournament histories. Brazil has won the World Cup five times (1958, 1962, 1970, 1994, 2002), the most of any team, and Argentina has won twice (1978, 1986), with a third in 2022. Their past triumphs foster a winning culture and high-pressure experience.

Player Talent: These nations consistently generate top players. Pelé, Ronaldo, Ronaldinho, and now Neymar, Hulk, Deyverson, Lucas Evangelista, Jhon Arias, Maguinho are from Brazil, whereas Diego Maradona, and now Lionel Messi, Angel Di Maria, Lautaro Martinez, Rodrigo de Paul, Julian Alvarez, Giovani Lo Celso are from Argentina. This trend will certainly continue, offering a large talent pool.

Youth Development: Both countries have strong youth development systems that generate international-caliber players. Although many top players from both nations now play in Europe, the home leagues in Argentina (Primera División) and Brazil (Série A) remain competitive, helping to develop local talent.

Tactical Innovation: Both nations' football coaches are known for their strategic approaches.

Passionate Support: Fans may motivate players. Both countries have large football-following populations that provide moral support.

These countries' players have experience in multiple international leagues, which may assist them adapt to diverse styles of play and conditions in a World Cup staged in different countries; therefore, I believe the next champion for the worldcup 2026 will be a south american country, brazil or Argentina to be more specific.
