The event is named after its long-term sponsor,
Moyglare Stud. It was formerly contested over 6 furlongs, and for a period it held Group 3 status. It was promoted to Group 2 level in 1979, and to Group 1 in 1983. Its distance was extended to 7 furlongs in 1992. In 2014 it became part of the Irish Champions Weekend fixture. The Moyglare Stud Stakes became part of the
Breeders' Cup Challenge series in 2009. The winner of the race now earns an automatic invitation to compete in the same year's
Breeders' Cup Juvenile Fillies Turf. ==Records==
