To be fair, I assume they did a "partnership" and not like just a sponsorship or something like that.  I am pretty sure that Stake didn't just outright paid Drake. The money and so forth part of the deal will probably not be pubic information or at least it is not somewhere I can find, which means to me the financials of this deal is totally mistery. However, I just assume that you can't just pay like 5 million to Drake and say "go share us to the world", that wouldn't really be smart on both sides because of unknown results. Drake could lose a lot if stake makes 100+ million on it, or stake could lose if it makes 100k. That is why I believe it must be some sort of partnership where both gain as much as they gain together.
