The Economics of Horse Racing: How Money Flows Through the Industry

Horse racing is one of the most popular sports in the world, which ensures that it is also one of the most lucrative.

Major events such as the U.S. Triple Crown, Royal Ascot, and the Saudi Cup ensure significant prize money is up for grabs, resulting in superstar equines typically accumulating more passport stamps than the average human. Equines from across the world typically descend on the United States at the end of every season after competing in Breeders’ Cup qualifying races in the hope of winning a Championship race during the two-day meeting.

However, the economics of horse racing revolves around more than simply the prize money that is offered in the biggest races on the calendar. So, how does the money flow through the industry?

The Core Engine

The economics in horse racing works slightly differently from country to country. In the United States, it revolves heavily around the Core Engine, which comes in the form of Pari-Mutuel wagering.

Bets that are placed are pooled together, with the track and stake taking a percentage ranging from between 15 to 20%. The remaining balance in the pool is then divided between those with winning wagers. Money collected from the takeout will fund the operational costs of the venue, as well as setting purses for races on the calendar.

Casinos & Gaming

The takeout typically isn’t sufficient enough to keep mid and high-tier racetracks operational, meaning that many racing states such as Ohio, New York, and Kentucky are tied to casino and slot machines  .

The revenues taken from casinos in these states will then have a direct impact on inflated purses, ensuring competitive racing and big fields are prominent. Tracks without casino and gaming operations typically tend to struggle in the United States, which has resulted in many closing their doors for good.

Business for Owners

The owners of racehorses typically spend millions getting involved in the sport, but the unpredictable nature of the Sport of Kings ensures that it is typically challenging to make a profit-making enterprise. Owners will put money into the sector, via daily expenses such as veterinary care, boarding and trainer fees.

However, the top horses in the country can win prize money, but an owner will never win 100% of the purse. In fact, their share likely stands at between 60 to 80%. The remaining share is split between the jockey and trainer.

Breeding and Bloodstock

The real money in the horse racing industry comes from breeding and bloodstock, with certain states such as Kentucky and Florida typically thriving in this sector. In the former, the breeding industry is worth a staggering $6.5 billion  and it supports around 60,000 jobs.

Some of the biggest sales in the sport are also completed in the state, with Keeneland and Fasig-Tipton’s auctions typically seeing over $700 million spent. Kentucky’s reputation as the U.S. horse breeding capital is secured, as they have a 47.8% share of all Thoroughbred foals in the United States.

This is significantly higher than the shares of 7.8% and 7.3% in New York and California, respectively.

What Impacts a Horse's Valuation & Stud Fee?

The valuation of a racehorse is largely dependent on a number of factors, ranging from past performances on the track and their lineage. Horses with proven winning form in Group or Graded stakes races will typically be sold for higher costs at stud, as there is a scientific chance that any offspring should be capable of reaching the same level.

Horses with proven lineage to previous champions will also be sold for higher valuations. Other factors that are considered when setting prices include the age of the horse, with younger horses typically having a better fertility rate when it comes to breeding.

Due to the vast amounts of money in breeding, it is likely that even the most successful thoroughbred champions could make more money once they have retired from racing than they had on track. This is a main reason why many talented high-class horses on the flat are retired early in their career to ensure that their valuation doesn’t decrease should they suffer a shock loss or if they were to suffer a major setback.

Who Are the Most Expensive Sires in 2026?

Stud values for top sires are extremely expensive, indicated by the top horses that are standing in 2026. Dubawi and Frankel are the two most expensive sires this year, with each standing for a price of $400,000. The most expensive American sire is Into Mischief, who is priced at $250,000.

The American sire has already produced two winners of the Kentucky Derby. This year’s Kentucky Derby-winning sire was Gun Runner, who stands at Three Chimneys Farm for a cost of $250,000. One of the most expensive younger sires is Triple Crown hero Justify, who stands at Coolmore for $200,000.
