Where does he purse money come from.?

The track.. From the Rake.. Here is a list of percentages taken from pools diff. tracks..

varies by state and by pool. The takeout from the win/place/show pool is usually the smallest, and the rake gets bigger for exotic bets (exactas, trifectas, etc.) and multi-race bets (pick-3, pick-4, and pick-6 wagers). Racetrack Takeout Percentage by Bet Type

As you can see from the takeout chart on the left, the WPS pools (Win, Place, Show bets) have the lowest takeouts. At Churchill Downs 16% of the money bet in the WPS pool is taken out before odds are shown or payouts made. The takeout for the exotic bets are higher - 19%. The more difficult the bet is to win, the more money the tracks take. Hitting a pick-6 is difficult enough, but at Woodbine racetrack in Canada they are taking over 26% of the money bet on the pick-6 before making a payout so take that into consideration when you are trying to hit the big one! These takeout percentages change often with new tax rules, so check with your local racetrack to get the latest and most accurate information.

So if an exacta pool has 100K bet .. The track rakes 25K off the top.. That's where claiming purses come from.. Also entry fee club house admission.. Stakes and Allowance are a bit different.

If your wondering what those percentages are.. OK..

Second is the Exacta pool

Third is the Trifecta pool

Fourth is the Pick 3 pool

Fifth is the Pick 6 pool Hope this helped..

Yes, the purse money?..... It goes into my pockets. :- )

...Billy Ray

The purse is the total monetary amount distributed after a race to the owners of the entrants who have finished in the (usually) top four or five positions. Some racing jurisdictions may pay purse money through other places. Most comes from bettors.

In horse racing, purse distribution may refer to the total amount of money paid out to the owners of horses racing at a particular track over a given period of time, or to the percentages of a race's total purse that are awarded to each of the highest finishers. Generally, a track’s purse structure comes directly from the projected amount of handle (the total amount bet by the public).
