>if you could build a model to predict markets, why will you post in to Kaggle to get $40k in prize instead of applying this model to your own broker account?
Because things aren't that simple. I find this argument very similar to that of devs who complain "I wrote this piece of code that made my company $3mil in revenue over the past year, but I only got paid a fraction of that, i am getting ripped off, oh woe poor me". If you could do that, you would have made it on your own and made that much money already.
Turns out, other people at the company are actually doing tons of work to make it possible to make that much revenue off your code. Same applies here. It isn't just as simple as having one good model at a single point in time to be able to make tons of money off it, there are a lot of other people doing their own work at those finance shops that make it possible for those models to bring in tons of money.
