The most expensive horses in the world are valued in millions of dollars. Such a high cost is due to loud victories at races, excellent pedigree, rarity of the breed, special training. Only a few people can afford such an animal, and some horses are not for sale at all.

Frankel

This particular horse is the most expensive in the world. He is a thoroughbred riding horse (English racehorse) of grey colour, born to Galileo and Kaind. The stallion is owned by Prince Khalid Abdullah of Saudi Arabia. 

Born in 2008, Frankel has competed in 14 races and has won all of them for nearly 3 million euros.

At the peak of his career, the stallion was valued at $200 million. Today he is only a sire, so the price has dropped to $131.6 million.
Despite this impressive sum, the owner is in no hurry to part with the famous stallion. Frankel provides excellent offspring, which is in good demand - there are already winners and prizewinners. It is not excluded that in the future the stallion will still get to the races.
