Mercedes leads the 2026 Constructors’ Championship by a substantial margin after securing victories in the opening rounds, with Kimi Antonelli and George Russell combining for consistent podium results that underpin the 56% implied probability. Their recent upgrade package and strong straight-line speed suit the power-sensitive Circuit Gilles Villeneuve, where cooler temperatures and historical Safety Car frequency have often rewarded reliable chassis performance. McLaren sits second in the market at 32% following competitive qualifying pace in Miami and ongoing development gains, though the team trails Mercedes by nearly 90 points. Red Bull, Ferrari, and the midfield squads face larger gaps in form and points, limiting their immediate threat despite targeted updates ahead of the Canadian weekend.
