Wealthiest Horse Racing Trainers In The World

There are few more lucrative sports on the planet than horse racing, with some of the biggest Grade 1s offering purses worth millions of dollars. Therefore, it should come as little surprise that some of the world’s top trainers earn hundreds of millions in terms of prize money throughout their career in the sport. 

Leading trainers will often be the preferred option for connections when it comes to training a potential champion, but which trainers rank highest in terms of prize money won on track during their career?

Todd Pletcher

Few trainers are able to come close to the success achieved by Todd Pletcher on track throughout his career. The Hall of Famer has won over $478 million in earnings throughout his career, training over 5,600 winners to date. His success has continued into the 2024 season to date, winning over $600,000 in prize money across the opening month of the year.

Steven Asmussen

Steven Asmussen is the only other trainer to have eclipsed $400 million in earnings during his career. The two-time Eclipse Award winner for Outstanding Trainer has won many of the big races on the U.S. schedule at least once, but he is still chasing an elusive success in the Kentucky Derby. 

The 58-year-old has trained over 10,000 winners throughout his career, but few come close to the prize money picked up by Gun Runner. Gun Runner won over $15 million during his career on track, which included a standout success in the Pegasus World Cup. Curlin also won over $10 million while in the care of Asmussen, with his most lucrative victory coming in the Dubai World Cup. 

Other horses to rank among his highest earners include Jackie’s Warrior, Untapable, and Midnight Bourbon. Asmussen has won three Triple Crown races during his career, with his most recent success coming in the 2016 Belmont Stakes with Creator.
