No insurance companies will provide a service like this since it's uncontrallbleand it's a personal will of the people, I doubt there will be a legal company who will implement such products that can make their company at loss. Maybe those who also own casinos will do that but with too many rules, classification, steps etc and with high premium since it's quite impossible to provide insurance for gambling.
If there will be such insurance companies that will offer it, I don't think that it will ever be in favor of the gamblers that would want to avail the insurance.
There will be more of the cons than the pros that they'll offer it.
It's favoring the company than the insurance buyers.
But that's just an if statement.
