Now I know that sportsbooks can be a bit more flightly – a run of favourites winning can hurt sportsbooks – and it’s much more likely than a run of luck on casino games for BIG affiliates.
The financials of sports and casino are not really comparable at all. With sports a winning situation tends to apply across the board and can really strap a book. Whenever your income depends on the success of living beings in high performance situations influenced by many factors beyond your control the outcome is a lot less predictable.
In casinos, winners are a lot more predictable and can be figured into the budget easily. The number of winners per played unit is pretty much predetermined – it’s called payout rate. Additionally, high jackpot wins do not affect the casino per se as the jackpots are paid into with each spin of the wheel and the money is already sitting there waiting to be paid out. It is easy for the casino to factor in the winners. The affiliates however are only affected by a small percentage of this and there is no telling who will be affected how much and when.
Casinos also pay the percentage to affiliates AFTER DEDUCTIONS, such as jackpot fees (in this case the affiliates have already paid their dues for the large win), administrative costs and the like.
Thus, with bundling, the income of an affliate becomes capricious, while the income of the casinos becomes completely even at a much higher ratio, since about one third of the earnings that is the affiliate percentage is not paid out.
The one third is only my personal experience and capricious by nature. Someone more proficient in math than me can go and figure out exactly what this costs affiliates overall, factoring in the payout rate. That will be the figure the casino looks at. For the individual affiliate however the result is periodically catastrophic, since we are not paid on the profitability of the casino but on that of the individual player.
