Simeone competed for Argentina at the 2024 Summer Olympics. On 19 November 2024, Simeone debuted for Argentina against Peru in a 2026 FIFA World cup qualification. In doing so, he became the second son of Diego Simeone to play for Argentina after Giovanni Simeone. On 25 March 2025, Simeone scored his first goal for Argentina in a 4–1 victory in the same competition against Brazil. On 27 May 2026, Simeone was selected in the 26-man squad for the 2026 FIFA World Cup by manager Lionel Scaloni. He started his first World Cup game in a 3–1 group stage win over Jordan a month later on 27 June.

Born in Rome when his father, Diego Simeone, was playing for Lazio, Simeone returned to Argentina to live with his mother at the age of four, and began his career with River Plate. In September 2019, he moved to Atlético Madrid's youth categories; as he had not signed a professional contract with River, the club was unable to retain him, and the move was later approved by FIFA. He then joined the Juvenil squad that same year.

Simeone is the son of his current manager at Atlético Madrid, Diego. His brothers Giovanni and Gianluca were also footballers, with the former having also played for Argentina internationally, and the latter retiring in 2025.
