Which Horse Has Won the Most Money in Its Racing Career?

Published on: June 6, 2022

By: Miles HenryFact Checked

My son is a big fan of horse racing, but he wasn’t sure which one earned the most money. He thought it might be Secretariat because of how much success and fame he had, but I knew there were many horses that outearned Secretariat. So, which racehorse tops the career earnings list?

Winx from Australia, won $18.7 million during her racing career making her the world’s highest money-earner. Second is Almond Eye from Japan who earned 18.3 million. However, neither horse is recognized by Equibase which has Arrogate, a U.S. horse that earned $17,422,600, as its top money earner.

While Winx may be the horse that won the most money in its racing career, there is another horse that earned even more, when the winnings are adjusted for inflation. I cover this topic and much more about top-earning horses throughout this article.

Horses that won the most money

Horse racing is a sport with a long and proud tradition. For centuries, people have been drawn to the excitement of watching these magnificent animals compete. Today, horse racing is enjoyed by millions of people around the world.

And while there are many great horses competing at the highest level, only a few have managed to be considered the top career earners. Among these leading money earners, are Almond Eye, Arrogate, and Winx.

Each of these horses has achieved horse racing immortality by winning some of the sport’s biggest races. They have also earned their owners huge sums of money in prize money and endorsements. But while are unique horses, they all share one thing in common: they are true champions.

Note: The top two money earners are female horses.

Highest earning racehorse in North America: Arrogate

The horse racing industry is a multi-billion dollar industry, with races held all over the world on a daily basis. While many horse owners race for fun or to make a little extra money, there are a select few who race for the big bucks.

The highest-earning racehorse in North America is named Arrogate, who has earned over $17 million in prize money. Arrogate’s biggest win came in the 2017 $12 million Pegasus World Cup, where he took home a massive payday.

Arrogate is a Kentucky-bred gray horse. He was named the World’s Best Racehorse, along with American Champion Three-Year-Old Male Horse of the year in 2016. With his last big win being the Breeders’ Cup Classic for the second time in 2017, he has total winnings of $17,422,600. Arrogate died on June 2, 2022, at the age of 7.

His winnings put him well ahead of the second-highest North American earner, Gun Runner, who won $11,524,826 million. Given the high purses that are up for grabs in horse racing, it’s no wonder that some owners are willing to invest millions of dollars in their horse’s career.

The horse that has won the most money after adjusting for inflation is the Thoroughbred gelding named John Henry. He did not have a great pedigree, nor perfect conformation, but regardless of his flaws, he could run.
