FIFA has appointed experienced Brazilian referee Wilton Sampaio to officiate the opening match of the 2026 FIFA World Cup between hosts Mexico and South Africa, entrusting one of football’s most high-profile fixtures to one of South America’s most accomplished match officials.
The opening game, scheduled for June 11, will officially launch the expanded 48-team FIFA World Cup, which is being jointly hosted by the United States, Canada and Mexico.
The tournament marks a historic milestone as the largest World Cup ever staged since the competition was first introduced in 1930.
Sampaio’s appointment reflects FIFA’s confidence in the Brazilian official, who has built a strong reputation over the years through his performances in major international tournaments.
The referee previously officiated matches at the 2022 FIFA World Cup in Qatar and has handled several high-profile fixtures in South American football under the Confederation of South American Football (CONMEBOL).
FIFA traditionally reserves opening matches for its most trusted and experienced referees because of the enormous global attention such games attract. Millions of football fans around the world are expected to watch the tournament curtain-raiser as Mexico face South Africa in a match that will set the tone for the month-long football festival.
To assist him, FIFA has appointed fellow Brazilians Bruno Pires and Bruno Boschilia as assistant referees. The pair have regularly worked alongside Sampaio during international assignments and are expected to provide continuity and familiarity within the officiating team.
Paraguayan referee Juan Gabriel Benítez has also been named as the fourth official and will oversee technical area matters while providing support from the sidelines.
The appointment adds another major achievement to Sampaio’s refereeing career, which has seen him become one of the most recognised officials in world football.
His selection underlines FIFA’s emphasis on experience and consistency as it prepares to manage the complexities of an expanded World Cup featuring 48 nations for the first time.
The tournament itself represents a significant evolution of the competition. After decades of featuring 32 teams, FIFA approved an expansion to 48 nations, increasing the number of matches and broadening participation across all football confederations.
Mexico, one of the co-hosts, will be eager to begin the tournament on a positive note in front of home supporters, while South Africa will be hoping to make an immediate statement on football’s biggest stage.
The opening match is expected to attract intense global scrutiny, not only because it launches the competition but also because it will provide the first glimpse of how the expanded World Cup format will unfold.
