Mercedes secured the 2026 F1 Constructors' Championship at the São Paulo Grand Prix with 652 points, a 142-point lead over Ferrari and only 129 points remaining across three rounds. The Silver Arrows built this advantage through superior adaptation to the new power unit and aerodynamic regulations, dominating the opening six rounds with multiple wins from Kimi Antonelli and George Russell. Consistent scoring from both drivers, combined with Ferrari's mid-season struggles, locked in the result after Antonelli claimed the Drivers' title the prior weekend. Trader consensus at 100% reflects this insurmountable gap. Only unprecedented post-race disqualifications across multiple events could theoretically alter the outcome at this stage.
