The Richest Racehorses: Which horses have won the most money?

The best racehorses do not always earn the most money. For example, the world-famous Frankel retired, having amassed around $3.6 million. That may sound like a considerable amount of money, but it pales into insignificance when it is compared to the highest-earning horses of all time. There is no doubt about it. There are some very rich racehorses out there, or at least, there would be if they got to keep their winnings. Here are the top five racehorses from around the world who have won the most money.
