This market will resolve according to the winner of the 2026 Sinquefield Cup, currently scheduled for August 8, 2026 to August 21, 2026. If this tournament is postponed after September 4, 2026, 11:59 PM ET, canceled, or a winner has not been declared within this timeframe, this market will resolve to "Other." If multiple players are declared winner, this market will resolve in favor of the player whose listed last name comes first alphabetically. The resolution source for this market will be official information from the tournament organizer, the Grand Chess Tour (https://grandchesstour.org/tours/2026/tournaments/2026-sinquefield-cup/); however, a consensus of credible reporting may also be used.
