This category includes the winners of the Indianapolis 500 race between 1950 and 1960, as they formed part of the World Championships, even though they were not run to Formula One regulations, nor are they referred to as Grands Prix. This category does not include drivers who have only won sprint races, which were introduced in the 2021 Championship. (Although as of the end of the 2023 season Oscar Piastri is the only driver who has won a sprint and has not won a Grand Prix.)
