American Pharoah will stand at stud for a princely sum.
Ashford Stud, Coolmore America's breeding facility in the United States, has confirmed a price of $200,000 per live foal.
A stallion typically can book 200 mares in a year, which would mean American Pharoah's first year as a stallion could be worth $40 million.
It's one of the most expensive prices that a horse has initially stood for. Other high-priced stud fees already announced for 2016 are Medaglia D'Oro ($150,000), Curlin ($100,000) and American Pharoah's grandsire, Empire Maker ($100,000), who just returned to the U.S. after breeding for five years in Japan. On Thursday, Gainesway Farms announced the country's leading sire, Tapit, will stay steady at his $300,000 fee for 2016.
It's not only American Pharoah that will cost a pretty penny for the rights to breed with. The horse's sire, Pioneerof The Nile, who stands at Winstar Farm, saw his stud fee rise from $60,000 this year to $125,000.
Zayat Stables, which maintained all the rights and prize money during Pharoah's racing career, sold an undisclosed percentage of the horse for breeding to Coolmore. Zayat Stables owner Ahmed Zayat has said that when he sells, he always keeps at least 25 percent of the horse's breeding rights, including those for Pharoah and Pioneerof The Nile.
Being a great Thoroughbred on the track doesn't guarantee success in the breeding shed. Secretariat, considered the greatest horse of all time, was disappointing as a stallion.
The offspring of famous horses sometimes become the money winners as stallions. One of the most successful stallions, A.P. Indy, was sired by 1977 Triple Crown winner Seattle Slew. The horse won eight of 11 starts, including the Belmont Stakes and Breeders" Cup, and had successful progeny.
Storm Cat, who only won half of his eight starts on the track, commanded a fee of $500,000 per live foal at the peak of his breeding career. His grandsires included Secretariat and Northern Dancer, who once commanded record fees of $1 million every time he was matched with a mare.
American Pharoah, who won nine of his 11 starts, including the Triple Crown, the Haskell Stakes and the Breeders' Cup this past weekend, arrived at Ashford Stud on Monday to begin his new life.
