Mercedes-AMG Petronas wins the 2026 Formula 1 Constructors' World Championship (confirmed by FIA by December 7, 2026)
After 15 of 23 season races, Mercedes-AMG Petronas leads the Constructors' standings with 538 points — a 160-point advantage over Ferrari (378 pts, as of ~September 27, 2026). With 8 remaining Grands Prix (Singapore, USA/COTA, Mexico, Brazil, Las Vegas, Qatar, Abu Dhabi) plus sprint points, 344 points remain in play. Ferrari would need a net 160-point advantage, which is practically impossible even in the most extreme scenario (Ferrari wins everything, Mercedes scores zero). Kalshi prices Mercedes at ~94%, Polymarket at ~87%, bookmaker implied probability ~91% (Mercedes -1000). Mercedes won 11 of 15 races to date; Kimi Antonelli also leads the Drivers' Championship with 302 points. The title will likely be mathematically secured at the US GP or Mexico City GP.
