SHAWN “JAY-Z” CARTER

 Co-founding Roc-A-Fella Records to capitalize on hip-hop music and to use it as a platform for urban fashion, Carter has grown his portfolio over the past 20 years and, according to Forbes, “has accumulated a fortune that conservatively totals $1 billion.” Through shrewd investments, acquisitions, and deals, his far-flung business kingdom includes Roc Nation and Tidal streaming service, among other ventures. Jay-Z also has a good eye for investments in innovative companies like Uber, beauty brand Julep, and stock trading app Robinhood.
