A year after winning the Triple Crown, American Pharoah has made the most of his life as a stallion.
The horse has been bred with more than 200 mares in 115 days, according to Ahmed Zayat, who owned the horse for its entire racing career and still owns an undisclosed share of his stallion rights.
Mares from around the world are being sent to Versailles, Kentucky, to Coolmore's Ashford Stud, which owns the majority stake in American Pharoah.
The horse is being bred at a rate of $200,000 per live foal, meaning that if 200 horses are born roughly 11 months after conception, the syndicate would gross $40 million. In general, roughly 15 percent of mares don't give birth to a living foal.
The $200,000 rate is the second highest in the thoroughbred breeding world this season, second to only Tapit ($300,000).
"I'm thrilled," Zayat said. "And I'm happy because he is happy."
American Pharoah won nine of his 11 starts, including the Triple Crown, the Haskell Stakes and the Breeders' Cup. The horse earned $8.6 million on the track.
