Welcome to the ARCI.


The ARCI (RCI) is the only umbrella organization of the official governing rule making bodies for professional horse and greyhound racing in North America and parts of the Caribbean.


ARCI sets standards for racing regulation, medication policy, drug testing laboratories, totalizator systems, racetrack operation and security, as well as off-track wagering entities.   ARCI's members are the only independent entities recognized to license, enforce, and adjudicate matters pertaining to racing.
