Kimi Antonelli has turned early-season uncertainty into a championship triumph. His speed was never seriously questioned, but his rookie year had been marked by costly mistakes, while he was comprehensively outperformed by Mercedes team-mate George Russell.
Many believed Mercedes had placed him under the spotlight too soon by handing him a front-running seat instead of allowing him to develop away from the intense scrutiny of a leading team. That criticism, in hindsight, carried some weight.
A season or two with a team such as Williams might have offered the teenager a gentler introduction to Formula One. Antonelli was only 18 when he inherited the seat vacated by Sir Lewis Hamilton, a responsibility that would have tested drivers with far more experience.
The questions were obvious: could he recover from the pressure, and could he control the exuberance that sometimes accompanied his breathtaking pace? Throughout it all, Mercedes boss Toto Wolff remained firmly in his corner, offering the young Italian the support he needed.
Wolff had brought Antonelli into the Mercedes junior programme when he was just 12 and had never lost faith in the belief that he had discovered Hamilton’s successor. He made that conviction clear to Antonelli both behind closed doors and in public.
Even so, doubts remained throughout the paddock. When I asked one team principal for an assessment at the beginning of the season, his verdict was blunt: Antonelli was “undoubtedly quick but prone to too many mistakes.”
In 2026, however, Antonelli has displayed remarkable composure, particularly for a driver who is still only 20. That age makes his achievement even more striking. Few young talents have shown such early brilliance: Stirling Moss won his landmark race at Goodwood on his 19th birthday in 1948, while Max Verstappen claimed his first Formula One victory in Spain at 18 in 2016. Antonelli now belongs in that rare company.
He quickly established a clear advantage over Russell, who began the campaign as the favourite and believed his long-awaited opportunity had finally arrived. Russell won in Melbourne with a spectacular opening statement, creating the impression that the title might be his to lose.
The championship’s decisive shift came in China, where Antonelli earned his first victory just one week after Russell’s Australian triumph. Mercedes had a chance to keep its rising star at bay, but Antonelli instead took control of the contest.
Russell, despite winning the Chinese sprint, appeared to take a psychological blow when Antonelli beat him by five seconds in the grand prix the following day. Antonelli had started from pole, another first in his rapidly developing career, and then maintained relentless momentum. He was also benefiting from Mercedes having the fastest car on the grid during the opening phase of the season, before rivals began to close the gap.

Successive victories in Japan, Miami, Canada and Monaco delivered another severe blow to Russell. He initially projected confidence, but it became increasingly clear that he was struggling to find the right way to extract performance from his Mercedes as the championship began to slip away.
Russell did endure the greater share of misfortune, and there may also have been a subtle preference within Mercedes for Antonelli. It was not a matter of deliberate wrongdoing, but a natural leaning towards the driver the team viewed as its next great star.
By then, the damage to Russell’s title hopes was substantial. Antonelli, expertly guided by Peter “Bono” Bonnington, Lewis Hamilton’s former race engineer, continued to collect points with impressive regularity. Even when he was not at his best, he was almost always in contention.
After going three races without a win—including Hamilton’s first victory for Ferrari in Barcelona, which ultimately proved to be a false dawn for the Italian team—Antonelli returned to the top step at Spa. The result produced another major swing in the standings: Russell was taken out after colliding with Hamilton on the opening lap, while Hamilton received a five-second penalty.
Antonelli resisted Charles Leclerc to secure the victory, extending his advantage to 45 points over Hamilton and 50 over Russell.
His most memorable performance may have come at Monza, where he won his home Italian Grand Prix from the back of the grid after taking an engine-change penalty. Mercedes had a fast car, a powerful new unit and a favourable strategy, but none of that diminished the quality of Antonelli’s recovery drive.
The crowd would almost certainly have preferred to see Ferrari win. Red shirts and banners dominated the grandstands, while Mercedes colours were difficult to spot. Yet Antonelli’s victory still elevated him to a new status in his homeland.
Another crucial moment arrived when Russell’s engine failed late in the Bahrain Grand Prix in Malaysia at the start of last month. That effectively settled the championship, even though Antonelli finished second behind a resurgent Max Verstappen and Red Bull. The points had been accumulating steadily, and Antonelli reinforced his position with a commanding victory in Austin last weekend.
He has now secured the Formula One world championship with four rounds still scheduled, although the planned Middle Eastern finales in Qatar and Abu Dhabi remain subject to the effects of the war. Should those races be cancelled, Imola is expected to host the alternative season finale.
For the driver born only 20 miles from Bologna, it promises to be a celebration of extraordinary scale.
