If the 2026 F1 Spanish Grand Prix is canceled or rescheduled to a date after Sep 20, 2026, this market will resolve to “Other.” This market will resolve in favor of the driver who is officially listed in first place in the Final Classification published by the FIA following the conclusion of the race. The Final Classification is typically released 30-60 minutes after the race ends and includes any applied time penalties and official adjustments. Disqualifications or changes made after the publication of the Final Classification will not affect market resolution. The timing of the podium ceremony does not determine the result for this market — only the FIA's published classification will be used to resolve this market. The resolution source will be the official Formula 1 website and a consensus of credible sports news reporting.
