The Kentucky Standardbred Breeders' Incentive Fund (KSBIF) was implemented in 2005 to ensure the strength and growth of the horse industry in Kentucky. The fund receives 13 percent of the 6 percent sales tax paid when breeding a stallion to a mare in the Commonwealth. The Kentucky Standardbred Development Fund (KSDF) is funded, in part, by a pari-mutuel tax paid by racetracks in Kentucky. The KSBIF and the KSDF, along with any other money contributed, appropriated or allocated from all other sources, fund the Kentucky Sire Stakes. The Kentucky Sire Stakes is administered by the KHRC. The Kentucky Sire Stakes is a culmination of a month-long series of preliminary races, with the biggest money earners getting a chance to compete in one of the richest finals in North America.
