Kimi Antonelli is a Formula 1 world champion at 20 years and 68 days old — the youngest in the sport's 76-year history — after finishing third Sunday at the Mexico City Grand Prix, a result that locked up the title with four races still left on the calendar.

Max Verstappen won the race at the Autódromo Hermános Rodríguez, with Lewis Hamilton second, 0.799 seconds back. Antonelli crossed the line 4.006 seconds behind Verstappen — more than enough to clinch it. He had entered the weekend needing only a ninth-place finish to seal the championship over Mercedes teammate George Russell, who trailed him by 123 points heading into Mexico City.

The result makes the Bologna-born teenager Italy's first world champion since Alberto Ascari won back-to-back titles for Ferrari in 1952 and 1953 — a 73-year gap that had become one of motorsport's longest-running sore spots for a country obsessed with the sport. It also breaks Sebastian Vettel's long-standing record for youngest champion, set in 2010, by more than three years.

A rookie-to-champion arc in two seasons

Antonelli was promoted to Mercedes' race seat for the 2025 season at just 18, filling the void left by Lewis Hamilton's move to Ferrari, and immediately drew comparisons — fair or not — to Ayrton Senna and Michael Schumacher as a generational talent out of Mercedes' junior program. Team principal Toto Wolff spent much of this season publicly trying to shield him from title talk, even as Antonelli piled up wins.

Sunday's race had its own chaos further back in the field: Charles Leclerc picked up a five-second penalty after contact with Hamilton in a lap-one battle for position, finishing fourth, with Lando Norris fifth. But the afternoon's real business had already been settled by the laps Antonelli needed to survive, not win.

YOUNGEST CHAMPION IN F1 HISTORY. FIRST ITALIAN SINCE 1953.

Antonelli's title arrives with four grands prix still to run this season, a cushion that reflects just how dominant Mercedes' car and his own consistency have been in 2026 — a sharp reversal after years in which Red Bull and Verstappen, and more recently Ferrari, had defined the grid's pecking order. Verstappen's win Sunday was a reminder that the Dutchman, denied a shot at a fifth-straight title fight, is still very much a factor as the season winds down.

Attention now turns to the Constructors' Championship fight and to a persistent subplot: speculation about Antonelli's long-term future, with Ferrari's interest in the Italian prodigy an open secret in the paddock even as he insists his focus is on winning with Mercedes.
