Kimi Antonelli is the youngest F1 world champion in history. The 20-year-old Mercedes driver sealed the 2026 Formula 1 title by finishing third at the Mexico City Grand Prix on Sunday 1 November 2026, breaking a record Sebastian Vettel had held for 16 years and ending Italy’s 73-year wait for a world champion. Antonelli clinched the crown with four races still to run, and he did it in only his second season in Formula 1 — a rise that has stunned even the people who have followed him since he was a boy in karting. The result trended per news coverage around the world within hours of the chequered flag.
How Antonelli sealed the youngest F1 world champion title in Mexico
Antonelli arrived at the Autódromo Hermanos Rodríguez knowing that ninth place or better would be enough to make him champion, whatever his rivals did. He started fourth on the grid, battled illness and exhaustion through a chaotic afternoon, and brought his Mercedes home in third place behind race winner Max Verstappen and Lewis Hamilton, who had started from pole position.
The race itself was full of drama. Verstappen took his sixth win in Mexico and the 74th of his career, beating Hamilton by 0.799 of a second, while Antonelli crossed the line about four seconds behind the Dutchman. The grand prix was stopped on lap 46 with a red flag after Valtteri Bottas crashed into the wall at the first corner, and the 33-minute halt came after two safety-car periods across the 71-lap race. Through it all, Antonelli kept the car on the road and the title in his hands.
As he took the chequered flag, his voice cracked over the team radio. “We did it, we did it,” he said, sobbing with joy. On the podium he stood between Verstappen, a four-time champion, and Hamilton, a seven-time champion — the driver he replaced at Mercedes. Together the three men on the stage held 12 world titles, and the newest one belonged to the youngest of them.
The result also reshaped the standings behind him. Antonelli now has 380 points and an unassailable lead of 119 points. Verstappen moved up to second on 261 points after his win in Mexico, with Hamilton third on 259. George Russell, Antonelli’s Mercedes team-mate and his closest rival before the race at 123 points behind, finished sixth after a 10-second penalty for a collision with Red Bull’s Isack Hadjar, and slipped to fourth in the standings. Russell was excused from post-race media duties by the team, with team boss Toto Wolff saying he was distraught after a race Mercedes felt he could have won.
The records the youngest F1 world champion broke
Antonelli won the title aged 20 years and 68 days, more than three years younger than Vettel was when he set the previous record. The list of Formula 1’s youngest world champions now reads:
1. Kimi Antonelli (2026) — 20 years and 68 days
2. Sebastian Vettel (2010) — 23 years and 134 days
3. Lewis Hamilton (2008) — 23 years and 300 days
4. Fernando Alonso (2005) — 24 years and 57 days
Vettel had held the record for 16 years, and he was among the first to congratulate Antonelli on breaking it. But the age record is only the headline. Antonelli is also the first Italian to win the drivers’ championship since Alberto Ascari in 1953, ending a 73-year wait for his country, and only the third Italian champion in the history of the sport after Giuseppe Farina in 1950 and Ascari. He is the fourth driver ever to win the title in his second season, joining Hamilton, Jacques Villeneuve and Juan Manuel Fangio.
He already held a string of youngest-ever marks before Mexico: the youngest driver to lead the championship, the youngest driver to start a race from pole position, and the youngest winner of the Monaco Grand Prix. He is the only driver in Formula 1 history to win multiple races as a teenager, and he had already won six races before his 20th birthday in August.
A season of nine wins: how Antonelli got here
Antonelli has won nine of the 19 races held so far this season, with 16 podium finishes. He ripped through the early part of the year with five wins in a row from China to Monaco, took his first championship lead in Japan, and arrived in Mexico knowing the title was his to lose. His win at the United States Grand Prix in Austin left the championship to be settled in Mexico, and he settled it at the first attempt.
The story is made more remarkable by where he started the year. Antonelli made his Formula 1 debut in 2025 at the age of 18, stepping into the Mercedes seat vacated by Hamilton, and he had yet to win a race when the 2026 season began. He was born on 25 August 2006 in Bologna, Italy, and joined the Mercedes young-driver programme when he was 11 years old. Before the season, his team-mate Russell had been the favourite for the title as the more experienced driver and an established race winner. Instead, Antonelli won nine races and sealed the championship with four rounds to spare.
His rivals were gracious in defeat. Verstappen, who has won three of his last four races including his sprint victory in Singapore, congratulated the new champion, and Hamilton — the man Antonelli replaced — shared the podium with him in Mexico. Even Russell, despite his disappointment, had been the benchmark Antonelli had to beat all season, and the 20-year-old beat him by more than a hundred points.
What the title means for Italy and Mercedes
For Italy, this is a moment 73 years in the making. Formula 1 chief executive Stefano Domenicali, himself Italian, said: “For 73 years, our country has waited for this moment.” Ascari’s titles in the early 1950s had stood as Italy’s only championships in the sport, and generations of Italian drivers — from Ascari’s successors to the modern era — had tried and failed to add to them. The youngest F1 world champion has done it at the age of 20, in his second season.
For Mercedes, Antonelli is the team’s first drivers’ champion since Hamilton’s last title in 2020. The team also leads the constructors’ standings with 630 points to Ferrari’s 504, and it could clinch that title in Brazil next weekend. Wolff praised Antonelli’s humility as much as his speed, calling him a new kind of driver that youngsters should look up to.
That humility showed in Antonelli’s first decision as champion: he will not take the number one on his car next year. He will keep racing with number 12, the number he won the title with, saying it is a special number for him and a way to stay grounded. He is the first driver to win a championship carrying number 12 since Ayrton Senna did so with his first title for McLaren in 1988, and he plans to wear a special tribute helmet to his idol at next weekend’s Brazilian Grand Prix.
What happens next for the youngest F1 world champion
The season is not over. Four races remain after Mexico, starting with the Brazilian Grand Prix next weekend and then Las Vegas, and Antonelli will race them as champion rather than challenger. The constructors’ championship is still to be decided, with Mercedes holding a 126-point lead over Ferrari, and the fight for second in the drivers’ standings between Verstappen and Hamilton will run to the end of the year.
Antonelli will have to wait to lift the official trophy until the FIA gala in Shanghai in December, but the moment that mattered came in Mexico City, 2,200 metres above sea level, in front of a roaring crowd at the Autódromo Hermanos Rodríguez. A 20-year-old who replaced the most successful driver in the sport’s history has now written his own name into its record books — as the youngest F1 world champion there has ever been.
