The result and the title arithmetic
Andrea Kimi Antonelli won the United States Grand Prix at the Circuit of the Americas. Charles Leclerc took second and Max Verstappen third. Lewis Hamilton was fourth, Lando Norris fifth, Isack Hadjar sixth, Oscar Piastri seventh, George Russell eighth, Liam Lawson ninth and Pierre Gasly tenth.
The finishing order mattered for the championship. Before the race, [1] set out what Antonelli needed to become champion: win in Austin, with Russell finishing lower than eighth and Hamilton below fourth. Antonelli won, but Russell was eighth and Hamilton fourth, so on that wording the second and third conditions were not met. Our input does not confirm the title outcome, so we leave it there.
Antonelli arrived in strong form. His recent finishes read 3, 2, 5, 1, 1 over the previous five rounds, the last two being wins in Spain and Italy. Mercedes came in leading the constructors’ standings on 578 points with 11 wins, ahead of Ferrari on 444. Leclerc’s second place was a step up on his run of fourth-place finishes in the three rounds before Singapore.
How the race ran
The timing data describes a clean, dry afternoon, with air at 27.0 °C and track at 36.6 °C. There were no safety cars and no red flags, but two virtual safety cars. Nineteen cars were classified. The fastest lap went to Leclerc, a 97.976 s on lap 42, which fits a Ferrari driver who finished second.
Strategy varied across the field. Antonelli ran a straightforward one-stop, medium for 24 laps then hard for 32. Norris (medium, then hard) and Piastri (medium, then hard) also made one stop. Leclerc started on softs, moved to mediums for 24 laps and finished on hards for 17. Hamilton followed a similar soft, medium, hard pattern. Verstappen went soft, soft, medium, with stints of 13, 18 and 25 laps, on his way to third.
There were 32 pit stops in total, the quickest at 23.4 s and the slowest at 40.4 s. The stewards issued two time penalties, and both were served. Russell received five seconds for leaving the track and gaining an advantage. Oliver Bearman received ten seconds for causing a collision. Russell still classified eighth.
What the models got right
Every model named Antonelli as the winner. Claude Keeper, Gemini Thunder, DeepThinker and the Baseline all picked Antonelli, Verstappen and Leclerc for the podium. That set was exactly right, although the order was not: Leclerc finished second and Verstappen third, the reverse of the call for places two and three. GPT Striker had Hadjar in third instead of Leclerc, so its podium set missed. Hadjar finished sixth.
On Brier score over win probabilities, where lower is better, DeepThinker was best at 0.45. GPT Striker followed at 0.485, then the Baseline at 0.5683, Gemini Thunder at 0.61 and Claude Keeper at 0.6354. The spread is notable. GPT Striker missed the podium set yet scored better than three models that got it exactly right, which suggests the Brier gap came from how much probability each model put on Antonelli rather than from the podium picks. DeepThinker is also the designated model of the race.
The common miss was Verstappen at second. He had won the Singapore and Malaysia rounds and was second at Azerbaijan and Spain, so the call had support in the recent results. [2] reported Leclerc fastest in FP1 ahead of Verstappen. Leclerc’s late-race pace, shown by the fastest lap, turned that into the second-place finish.
The grid after Austin
Before the race, Mercedes led on 578 points, Ferrari had 444, McLaren 337 and Red Bull 329. Mercedes had [3] to an upgraded specification introduced two races earlier, and Antonelli’s win suggests that worked for him. Russell took a five-second penalty and finished eighth.
Ferrari took a second and a fourth, with Hamilton fourth in FP1 and fourth in the race. McLaren brought minor front-of-car upgrades and small floor changes, and Norris and Piastri finished fifth and seventh. Norris had complained before the race that the track is very bumpy. Red Bull added a front-wing update and named improving the car’s behaviour over bumps as a priority. Verstappen’s third and Hadjar’s sixth give them a base to build on, and Hadjar’s FP1 lap had been deleted for track limits.
Further down, Lawson was ninth and Gasly tenth, with Lawson having rounded out the top ten in FP1. Alpine sat sixth in the standings on 77 points and RB fifth on 96. Aston Martin, tenth on 7 points, had spoken of Honda power unit problems after Singapore, and Honda was preparing software and settings changes to improve turbo lag control. Neither Alonso, Stroll nor Cadillac’s drivers appear in the top ten.
