Bookmakers doesn't make money if Sinner lose or win. They make money if you gamble on it.
This is what usually happens if there’s no fixing involve, just the normal flow of business.
But if a game is already fixed, that’s a different story. Bookies might work together with the league and get inside info on what’s going to happen. So instead of just acting as the middleman for bets (which is what they normally do), they’d start taking bets like the house and even bet against other sportsbook which does not have the info.
If this were to happen, then it would explode on all news outlets and reports would flow against that major league office.
Like what some have mentioned, if major leagues secretly fix their games to bet bettors, then everyone would know about it. I would be surprised if they would do it given that there are tons of risked involved in this act. Obviously, if they were to fix their games, it would backfire them tenfold given that it would lose all the trust they have established all over the years.
A lot of fixing happens in smaller leagues but big leagues I am doubtful about it.
While the games might not seem like they are fixed and they are difficult too, we can never know for sure. But we have to aceept that something might be fixed and bet hoping that our luck runs on the correct side of the fix.
I definitely agree with you.
Given the risks involve and the reputation they have built over the years, it is just not worth it to lose its player base just to combat against its own bettors. Long-run, this would be their worst decision to make in the event they do it.
