Mercedes leads the 2026 constructors’ standings with 379 points to Ferrari’s 307 after consistent race and sprint results from drivers Kimi Antonelli and George Russell, giving traders a 53% implied probability for the Italian Grand Prix win. Ferrari has narrowed the gap through an aggressive upgrade program featuring dozens of aerodynamic and power-unit changes, most recently challenging at recent rounds and positioning Charles Leclerc and Lewis Hamilton as strong Monza contenders. The 48% price on Ferrari reflects its home-circuit strength at the high-speed Monza layout alongside ongoing development momentum. Lower probabilities for Audi, Williams, and others mirror their mid-pack points hauls and limited recent pace gains, leaving the top two teams’ form and reliability the decisive factors heading into the September 6 race.
