We read about his wife earlier on in the list, and now here's the other half of the power couple. Whilst Jay-Z is undoubtedly a rap legend and a major star, he's not the global icon that his wife is, and nor has he sold as many records. So how is it that he comes in higher up on this list?
The answer is that he's got serious business smarts. He created Rocaware clothing, built up the brand, and sold it for $204m. He co-owns Roc-A-Fella Records and is the principal owner of the streaming service Tidal. He has shareholdings in Arsenal Football Club, the New York Jets, and a series of nightclubs. In short, Jay-Z has invested his money wisely, and seen major returns on it over time. His money enables him to help the needy - he personally donated $1m to the victims of Hurricane Katrina.
