In order to compile our ranking of the richest rappers, we use the same procedures employed in the calculation of our annual billionaires list: poring over financial documents, valuing major assets, and consulting with analysts, managers, attorneys and other industry insiders.
Drake’s net worth grew 50% over the past year to $150 million, boosted by holdings ranging from real estate to his Virginia Black whiskey, as well as a lucrative tour and new residency at the XS Nightclub in Las Vegas.
Even after claiming to be $53 million in debt in 2016, Kanye still holds a net worth of $240 million with the majority of it stemming from his partnership with adidas.
Diddy’s $740 million net worth comes from his majority holding in Ciroc and his tv network Revolt.
