We have to ask ourselves to what extent this story is actually true. If you were to win that much money, would you share that information on the internet? Do not think so. There are many influencers active. The story may be real, but when things seem too good to be true, they often are. It is indeed a huge amount that is mentioned. I know the Superbowl is famous with big bets.
Sometimes when you heard something from an influencer or famous people in the internet talking about a website, services, product, etc. you will find it obviously as a sponsored content even though they don't announce it.
A $500,000 bet is not risky if this amount is just a spare to you, considering it's drake, although I don't know what kind of risk management he do, but based on the news seems like it's not the first time he bet such amount.
