Kimi Antonelli Makes Formula 1 History as Youngest World Champion at 20

Kimi Antonelli needed only ninth place at the Mexico City Grand Prix to become Formula 1's youngest world champion. The 20-year-old Italian did considerably better, finishing third and securing his first world title with four races still remaining in the 2026 season.

The Mercedes driver broke a record held by Sebastian Vettel since 2010, when the German won his first championship at 23. Antonelli was just 20 years, two months and seven days old when he crossed the finish line in Mexico City on November 1.

The race was won by Max Verstappen, who held off Lewis Hamilton by just 0.799 seconds. Hamilton finished second for Ferrari, while Antonelli completed the podium after starting fourth.

It wasn't an entirely straightforward afternoon. A serious accident involving Valtteri Bottas interrupted the race with a red flag, while a later collision involving Arvid Lindblad brought out the Safety Car. Antonelli moved into third after the restart and held the position to the finish.

The championship comes in only his second Formula 1 season. Antonelli joined Mercedes in 2025, replacing seven-time world champion Lewis Hamilton, who had moved to Ferrari. At 18, he became one of the youngest drivers to race for the team, arriving with considerable expectations after his rapid progress through junior motorsport.

By the Mexico City Grand Prix, Antonelli had collected nine victories and 380 championship points. His lead over Verstappen, who moved into second place in the standings, had reached 119 points, putting the title beyond the reach of his competitors.

His achievement also carries particular significance for Italian motorsport. Italy had waited 73 years for another Formula 1 drivers' champion. The last was Alberto Ascari, who won consecutive titles for Ferrari in 1952 and 1953. Before Ascari, Giuseppe Farina had claimed the inaugural Formula 1 World Championship in 1950.

Antonelli is now the third Italian driver to win the title and the youngest world champion in Formula 1 history. He joins Lewis Hamilton and Jacques Villeneuve among the drivers who secured their first championships in their second season.

With four races remaining, Antonelli will arrive at the next Grand Prix in Brazil already wearing the world champion's crown.
