Yeah, that's the conclusion I am coming to as well. The people with good models aren't going to talk about them. Even if they need investment they'll seek it privately. I guess I was thinking of a market where you can 'invest' your money in someone's model and they take a percentage of your winnings (that's their incentive for adding your money to the pool). Then it's a democratised race for whoever has the best model.
In horse racing where the bets are done via parimutuel[1], the challenge is that there's an upper bound on how much you can "invest" in a given wager without changing the odds. This makes it less likely that an expert will seek outside investment unless their model has them betting "wide" (lots of small bets vs. a few large ones).
Lol. The people who have the best models are often billionaires, have funds that manage hundreds of millions, and will employ hundreds of people on their own dime...they don't need to make a percentage on your $1000 investment.
Btw, these websites already exist but no-one on there makes any money. You don't need a lot of capital to make money in sports betting (because you turn your capital over so many times a year), there is no reason for a good sports bettor to use those sites to publicise themselves.
Here's an idea from an Australian website where you can build a very basic model, using past results (which are of course no guarantee of future performance) and then sell it. Or alternatively, you can buy "qualifiers" for these systems for a small fee.[1]
