sounds like an opportunity. as horse racing has a monetary reward associated with success one imagines a moneyball sort of play that you can compound by betting on your horse which the oddsmakers are going to handicap because it "doesn't have the pedigree" (at least the first few go arounds)
Here's a question though (can vary by country and racing industry), how do the winnings from racing (as a distribution) compare to the earnings from pedigree breeding, stud fees, sperm straw sales, etc.?
I agree there's room for disruption, just as there is from (say) the iron grip of the US Home Owners Associations and other cartels, but expect a lot of regulatory push back from the insiders.
The, ah, American Quarter Horse Association won't let any old nag run if they can help it.
Money would count, but I dare say it'd need a bit of crafty social engineering running in parallel to crack in.
Caveat: I'm not a horse racing / polo insider - I did some contract work years back and rubbed shoulders with a bunch of millionaire horsey types.
