Coolmore

Coolmore is a privately owned, globally active thoroughbred horse breeding, racing, and sales organization based in Ireland. It brings together breeding farms, a high-profile training operation at Ballydoyle, and a large international sales network. The group is widely regarded as one of the most influential forces in modern thoroughbred racing, with a track record of breeding and racing elite performers.

Coolmore's day-to-day operations are centered at Ballydoyle in County Tipperary, where trainer Aidan O'Brien and his staff oversee the development of many of the group's horses. The operation has produced numerous classic and Group 1 winners across Europe and beyond, and its horses compete at major race meetings around the world.

Beyond Ireland, Coolmore maintains breeding and stallion operations in other countries, including the United States and Australia. The US base includes Ashford Stud in Kentucky, among other properties, reflecting its global reach in breeding, raising, and standing stallions. The company also runs a global sales program, and yearlings and horses from its farms are regularly offered at major auctions.

Coolmore's influence on bloodlines has shaped modern pedigrees through successful stallions and progeny on track, contributing to a consistent pattern of high-level success in both breeding and racing. The organization remains privately held by John Magnier and partners Michael Tabor and Derrick Smith, continuing to invest in top talent and state-of-the-art facilities.
