After tier 9 it resets back to 1 through 9 again with different players if you have the ones from the previous rewards. It just keeps resetting after 9 over and over again.
Fan rewards already go up to 9. A bonus level unlocks after tier 7. Then the rewards come at 40 and 55k. Just one legend per reward though. Then after you pass 55k a new reward starts with new players that are available and the more you spend it just keeps going and starting over.
