Button: 2026 regulations are make-or-break for Hamilton at Ferrari

Jenson Button believes the sweeping 2026 Formula 1 regulations will define the Lewis Hamilton–Ferrari era — either catalyzing a return to his very best or prompting the seven-time champion to consider walking away.

A reset year that will test everyone

With chassis, aero and power unit rules all set for a major overhaul, Button sees 2026 as a career inflection point for Hamilton. If Ferrari nails the concept, Hamilton’s move could be vindicated in spectacular fashion. If not, the questions will get louder.

For now, all roads lead to the most consequential rule change of the hybrid era — and Hamilton’s biggest gamble.
