That was nearly $2 million more than the previous record for a filly when Cash Run sold at the 2003 Keeneland November Breeding Stock Sale, the Lexington Herald-Leader reported.
John Ferguson, acting for Sheikh Mohammed bin Rashid al Maktoum, the crown prince of Dubai and defense minister of the United Arab Emirates, won a bidding war against John Magnier, head of the Irish horse empire Coolmore.
During her racing career, Ashado won seven Grade One stakes, earning $3,931,440 for her owners, who raced as Starlight Stables. She was the only filly to win both the Kentucky Oaks and the Breeder's Cup Distaff.
Geoffrey Russell, the Keeneland sales director, said Ashado contributed to a $98.1 million day, up 21 percent from last year.
"The sale of Ashado -- once in a lifetime," Russell said. "She reeked of class and displayed it brilliantly today."
