Thirteen seconds clear in Austin: Antonelli wins, Mercedes take the constructors' title, and the crown waits a week

The race was won on the first lap and then defended with a spreadsheet. Kimi Antonelli started from pole at the Circuit of the Americas on Sunday, opened a two second lead before the field had settled, and then did the thing his rivals would not: he stopped once. While Ferrari and Red Bull brought their cars in twice, Mercedes kept the 20 year old out, moved him from medium tyres to hards, and watched him briefly surrender the lead and take it straight back, passing Charles Leclerc on lap 32 just after Max Verstappen's slow second stop had tangled the order behind him. From there it was arithmetic. Antonelli won the United States Grand Prix by 13.078 seconds, his ninth victory of the season, with Leclerc second and Verstappen third.

The championship nearly ended on the same afternoon, and the nearly is the story. Antonelli could have taken the title in Austin if Lewis Hamilton had finished fifth or lower and George Russell ninth or lower. Hamilton, instead, drove to fourth for Ferrari, and Russell, carrying a five second penalty for gaining an advantage on the opening lap, still dragged his Mercedes home in eighth. So the mathematics survives one more week, barely. Antonelli leads Russell by 123 points and Hamilton by 124, with a maximum of 125 still available. Ninth place in Mexico City next weekend, even if Russell wins the race, makes him champion.

His own team principal said the quiet part out loud. Toto Wolff called it the best race Antonelli has delivered so far, the race of a champion who is not the champion yet. Antonelli himself kept it flat: it was the result they needed, the whole team deserved it, and hopefully they can clinch it very soon. Behind the top three, Lando Norris was fifth for McLaren, Isack Hadjar sixth, Oscar Piastri seventh, and Liam Lawson and Pierre Gasly took the last points. With Antonelli and Russell both in the top ten, Mercedes also closed out the constructors' championship on Sunday, which means the only trophy left undecided in this season is the one with a name on it.

What waits on the other side of Mexico is a record that has stood for a generation. If Antonelli finishes the job, he passes Sebastian Vettel, who won his first title in 2010 at 23, and becomes the youngest drivers' champion the sport has had. He already holds the records for the youngest driver to lead the championship, to start from pole and to win at Monaco. Records like that usually arrive at the end of a long apprenticeship. His has lasted two seasons.

Our call is that Mexico is a formality and everyone in the paddock knows it, including Russell, whose only route now involves winning while his team mate finishes tenth or worse in a car that has not finished that low all year on pace. The more interesting question Austin posed is what a 20 year old champion does to the market around him. Mercedes have built their next era around a driver who may hold the sport's biggest record before he can rent a car in half the countries he races in, and Ferrari and Red Bull are now planning 2027 against a benchmark who is still improving. The coronation is delayed by a week. The era is not.
