Mercedes driver Kimi Antonelli became the youngest world champion in Formula One history after finishing third at the Mexico City Grand Prix. The Italian secured his first drivers' title at age 20, completing a rapid rise in only his second season in the series.
Antonelli displaced Sebastian Vettel as the youngest title winner by a wide margin. Vettel was 23 years and 134 days old when he claimed his first championship in 2010. Antonelli is the 36th driver to win the Formula One world championship and the second consecutive first-time champion, following Lando Norris's victory for McLaren in 2025.
The achievement also ended a 73-year wait for an Italian drivers' champion. Italian racers won three of Formula One's first four titles: Giuseppe Farina took the inaugural championship for Alfa Romeo in 1950, and Alberto Ascari won for Ferrari in 1952 and 1953. No Italian had matched them until Antonelli completed his 2026 campaign.
His route to the title began after an uneven rookie season. Antonelli joined Mercedes in 2025 as Lewis Hamilton's replacement, taking one of the most closely watched seats on the grid. He earned his first Formula One victory at the Chinese Grand Prix in March 2026 and then won five races in succession, building a championship lead that he retained for the rest of the season.
Further wins followed in Belgium and Spain. Between those victories, Antonelli produced one of the season's most dramatic results at Monza, recovering from 19th on the starting grid to win the Italian Grand Prix. That made him the first Italian winner of the country's home race since Ludovico Scarfiotti in 1966.
Mercedes teammate George Russell had entered the year as the leading title favorite and won the opening round in Australia. Antonelli's run of victories changed the balance inside the team and the wider championship, leaving Russell increasingly overshadowed as the younger driver converted early momentum into a lasting points advantage.
Third place in Mexico City was enough to settle the contest without requiring another race win. It capped a season in which Antonelli combined a decisive spring streak with victories on different circuits and a high-profile comeback at his home event. The championship also placed him in a historically even group: of the 35 champions before him, 18 finished their careers with one title, while 17 won at least one additional crown.
Whether Antonelli ultimately joins the multiple champions cannot be known from his breakthrough season. His first title nevertheless establishes two clear records now: he is Formula One's youngest champion and the first Italian to win the drivers' championship since Ascari. Achieving both in his second year makes the Mexico City result a defining moment for Mercedes, Italian motorsport and the latest generation of Formula One drivers.
