Wolff: Mercedes Knew Antonelli Was Ready the Moment Hamilton Left

Toto Wolff says Mercedes needed only seconds to decide Kimi Antonelli would replace Lewis Hamilton, revealing he knew the call the moment Hamilton confirmed his Ferrari switch. Antonelli has since clinched the 2026 drivers’ title at the Mexico City Grand Prix, vindicating one of Formula 1’s boldest promotions.

Why it matters:

Putting a teenager straight into a factory Mercedes seat was widely viewed as a gamble. Wolff framed it as a calculated decision backed by data from Antonelli’s dominant F4 and Formula Regional seasons, rather than a leap of faith.

The details:

• Wolff recalled Hamilton telling him at his house that he was joining Ferrari: “The moment he confirmed that he was going to Ferrari, instinctively I knew that Kimi is going to go in the car.”
• He then called Bradley Lord and James Allison. According to Wolff, both responded: “What are you even talking about?”
• Mercedes saw little need for more junior-category seasoning. Wolff said: “We had the data... He confirmed it by his success in cars in F4 and in Regional. Go for it. Undercut.”
• Wolff pinpointed Antonelli’s five consecutive wins as the run that made the title feel inevitable, saying he knew Mercedes just had to provide the car.

What’s next:

Antonelli’s championship closes the succession question around Hamilton’s exit and opens a new Mercedes era. The next challenge is defending the crown with a car good enough to keep him at the front.
