Kimi Antonelli became the youngest Formula One world champion in history after finishing third at the Mexico City Grand Prix on Sunday, November 1, securing the 2026 Drivers' Championship at 20 years and 68 days.
The Mercedes driver broke Sebastian Vettel's record, set when the German won his first world title aged 23 years and 134 days in 2010, by more than three years. Antonelli also ended Italy's 73-year wait for a Formula One world champion, becoming the country's first title winner since Alberto Ascari in 1953.
The historic achievement came in an eventful 71-lap race at the Autódromo Hermanos Rodríguez, where Red Bull's Max Verstappen took victory ahead of Ferrari's Lewis Hamilton, while Antonelli completed the podium.
Antonelli entered the race needing only a ninth-place finish to guarantee the championship, regardless of how his closest challengers, Hamilton and Mercedes teammate George Russell, performed.
Starting fourth on the grid, the Italian kept himself in contention through the opening stages as Charles Leclerc took the early lead for Ferrari following an aggressive battle with teammate Hamilton.
Leclerc was subsequently handed a five-second penalty for leaving the track and gaining an advantage during the opening-lap incident. Verstappen capitalised on the disruption to move ahead of Hamilton and challenge for the lead.
Hamilton expressed frustration over the team radio, questioning the stewards' decision and the advantage Leclerc had gained. However, the five-second penalty eventually affected Leclerc's race strategy, allowing Verstappen to take control after the pit stops.
Antonelli meanwhile maintained his position among the leading drivers, managing his tyres and extending his opening stint beyond 40 laps before making his pit stop on lap 44.
The race was interrupted shortly afterwards when Cadillac's Valtteri Bottas suffered a heavy crash at Turn 1 following a front-left suspension failure. His car struck the barriers, prompting an initial Safety Car before race officials brought out the red flag on lap 46 to allow repairs.
Bottas was slow to emerge from the wreckage but eventually walked away and was taken to the medical centre for precautionary checks before being released without injury.
The interruption forced the remaining drivers back into the pits before the race resumed with a standing restart on lap 47. Verstappen led Leclerc, Hamilton and Antonelli, who had dropped to fourth following the revised restart order.
Hamilton immediately challenged Verstappen for the lead, moving ahead of Leclerc before briefly making contact with the Red Bull driver. The Ferrari driver settled into second as Antonelli targeted the remaining podium position.
The Italian subsequently passed Leclerc at Turn 1 to reclaim third, leaving the Ferrari driver under pressure from McLaren's Lando Norris in the closing stages.
Another interruption followed when Norris' teammate Oscar Piastri made contact with Racing Bulls driver Arvid Lindblad, sending the latter into the barriers and triggering a late Safety Car.
Verstappen maintained his advantage when racing resumed with eight laps remaining, holding off Hamilton's challenge to cross the finish line first in 2:20:28.772.
Hamilton finished second, 0.799 seconds behind, while Antonelli crossed the line third, 4.006 seconds behind the winner, securing the podium that confirmed his maiden world championship.
The victory capped a remarkable second season in Formula One for Antonelli, who joined Mercedes in 2025 after progressing through the team's junior programme.
Born in Bologna, Italy, on August 25, 2006, Antonelli was identified as a promising talent during his karting career and joined Mercedes' junior programme in 2019 at the age of 12.
He won the Italian and ADAC Formula 4 championships in 2022 before claiming the Formula Regional European and Middle East titles in 2023. He then moved directly into Formula 2 in 2024, skipping Formula 3, before Mercedes promoted him to its senior team alongside George Russell for the 2025 season.
His first Formula One campaign produced three podium finishes, but his performances improved significantly in 2026, with nine Grand Prix victories helping him establish an unassailable lead in the championship.
Reacting to his achievement, an emotional Antonelli credited Mercedes and his family for supporting his journey to the top of the sport.
"We did it. I wouldn't be here without Mercedes, without my family. I am very grateful for this moment, it will be with me forever. I am speechless, just trying to process what happened."
He also described sharing the podium with Verstappen and Hamilton as an incredible experience, expressing his anticipation for future battles with the two experienced champions.
Antonelli's triumph places him among Formula One's youngest and most historic champions, while his achievement marks a new chapter for Italian motorsport.
