(CNN) - In horse racing, the rich tend to get richer. Prize funds are growing, and in a select handful of uber-rich races the pot can be eye-popping.
In 2018, the Pegasus World Cup boasted the highest prize money in the world with bumper prize money of $16 million.
Simply put, the sport of kings can yield a king's ransom.
Here is a look at some of the richest events on the horse racing calendar.
Pegasus World Cup
Introduced in 2017 as the richest race on the planet , the Pegasus World Cup is the epitome of American lavishness. The nine-furlong (1⅛ miles ) race is run over a dirt track at Gulfstream Park, Florida and is intended as a showdown for experienced racers of four years old or above.
For its second running in 2018, the prize pot was boost by $4 million to $16 million with an entry fee for each of the 12 slots of $1 million. The organizer added the rest.
The winner, Gun Runner, collected an astonishing $7 million in 2018.
However, for 2019 the prize pot will be split across two Grade 1 races -- the Pegasus World Cup Invitational and the new Pegasus World Cup Turf Invitational over 1 3/16 miles.
The revamped Pegasus World Cup Invitational will command a prize fund of $9 million with $4 million going to the winner, while the turf race will offer a pot of $7 million with the winner bagging $3 million.
Entry to each race costs $500,000 with an owner scooping a bonus $1 million if they win both events.

The Dubai World Cup
Due to the new format of the Pegasus World Cup, the Dubai World Cup can now regain its position as the richest horse race in the world.
Held at the Meydan Racecourse, United Arab Emirates (UAE), the Grade 1 race has been run every year since 1996, marking the end of the UAE racing season.
The prize fund has been boosted to $12M and the winner of the 2019 edition will take home an eye-watering $7.2 million.
Godolphin, the racing stable of Dubai ruler Sheikh Mohammed bin Rashid Al Maktoum, has particularly enjoyed the event. It celebrated its record seventh victory in 2018 as Thunder Snow, trained by Saeed bin Suroor, set a new dirt-track record.
Run over mile-and-a-quarter (10 furlongs), the race invites four-year-olds or above from the Northern Hemisphere and three-year-olds or above from the Southern Hemisphere.

Australia hosts the world's richest race on turf.
Run over six furlongs, The Everest brings the world's top sprinters together at Royal Randwick, Sydney. It's only been in existence for two years but has already surpassed the Melbourne Cup as the country's richest race.
There's only been one winner of the race since its inauguration in 2017, with Redzel clinching back-to-back titles.
There are 12 places up for grabs, each costing the owners $600,000, but the payoff can be huge. Race organizers hiked up the prize money in 2018 with the winner swiping $4.5 million.
The Everest's prize pot is set to rise to $14 million in 2019 and $15 million in 2020.

The Breeders' Cup Classic
Back to the United States for another giant in the world of sprint racing. The Breeders' Cup Classic attracts the best thoroughbreds, with the winner being treated to just over half of the $6 million prize pot.
Restricted to three-year-olds or above, the race is considered the unofficial fourth leg of the prestigious Triple Crown and is often a big factor in deciding Horse of the Year.
The mile-and-a-quarter event run on dirt has been in existence since 1984, and the latest edition was won by the aptly named Accelerate.
Uniquely, the race is held at a different location each year and has only once been hosted outside of the USA -- the 1996 edition was held in Ontario, Canada.
