If it's just a partnership with stake, with stake being the one in charge of the funding, what if he successfully wins one of his bets with such a large amount of money? Will Stake also be the one to take the winning reward, or will it go to his pocket?
 
I think I prefer to go with the guy who says it's just like a stake reward for him with a bonus for promotion, which he could possibly use to wager in a few sports games. Such an explanation is fair enough considering the kind of figure that Drake is.
