Red Bull's triple world champion Max Verstappen has held off a charging Lewis Hamilton to take the 50th win of his Formula One career - and record-equalling 15th of the season - at the US Grand Prix.
Mercedes driver Hamilton finished second, a mere 2.225 seconds behind, with McLaren's Lando Norris third at the Circuit of the Americas at Austin, Texas.
The victory was Verstappen's third in a row at Austin and, with four races to spare, equalled the record he set last year for most wins in a single season.
Dominant Red Bull and Verstappen, who started in sixth place, have already secured the constructors and drivers titles.
"The whole race, I was struggling a lot with the brakes," said Verstappen, after one of his closest wins of the year. "You could see it was very close to the end."
Lining up on the front row, Norris seized the lead from polesitter Charles Leclerc into the first corner, but his hopes of taking a first win in his 100th start faded by the half distance.
Verstappen was fifth by the end of lap one and moved through the field, starting on medium tyres and pitting for more on lap 17, using the drag reduction to take the lead from Norris on the 28th of 56 laps.
Verstappen did not just disappear into the distance, with the champion's brake issues giving Mercedes hope they might reel him in with an upgraded car.
On fresher mediums on the final stint with Verstappen on hards, Hamilton started the last lap just 1.8s behind, after being 5.3s adrift, when he passed Norris for second with seven laps remaining.
"We were catching them towards the end and I was hopeful, but we needed some more laps," said Hamilton.
Ferrari's Carlos Sainz was fourth, with Red Bull's Sergio Perez fifth and Leclerc sixth.
George Russell was seventh for Mercedes, ahead of Alpine's Pierre Gasly, Aston Martin's Lance Stroll and AlphaTauri's Yuki Tsunoda, who also took a bonus point for fastest lap right at the finish.
Verstappen increased his unassailable lead over Mexican Perez to a whopping 228 points.
Alpine's Esteban Ocon was the first retirement, his race ending on lap seven, after a first-lap collision with McLaren's Oscar Piastri.
Australian rookie Piastri was then retired by his team four laps later.
The Aston Martins of Fernando Alonso - who retired with a rear suspension failure - and Stroll, and the two Haas cars of Kevin Magnussen and Nico Hulkenberg started from the pit-lane, after overnight changes.
