Coolmore saw off Godolphin in a bidding war at the Tattersalls Yearling Sale on Wednesday to land a son of Kingman for 1,100,000 guineas.
The colt is the first foal out of Fastnet Rock mare Turret Rocks, who won one Group 2 and two Group 3s when trained by Jim Bolger, and was sold by Corduff Stud after being bred by Farmleigh Bloodstock.
MV Magnier won the bidding war with bloodstock agent Anthony Stroud, who stood alongside David Loder and trainer Charlie Appleby.
David Egan of Corduff Stud said: "He is a magnificent horse, he really is. I am delighted they bought him, I was not sure they were on him, but they stood up and bought him. It is great.
"This horse was bred by John Corcoran and he bred the horse with Jim Bolger, and bought him out in training.
"John had a vision of what he wanted to do with the horse, he had a plan and facilitated a way to make it happen. He owned this horse in with his children, Andrew and Roseanne O'Grady Walshe, through Farmleigh Bloodstock.
"She is a beautiful mare, she is by Fastnet Rock, she is big, she is robust, she is strong. She was so honest on the track and John, unfortunately is not with us, but he was very involved in the mating. He chose Kingman, it is great.
"The bidding took a long time, but it got more enjoyable as we went on!"
