Jay-Z

Net worth: $2.5 billion. Hip-hop's first billionaire built a conglomerate that spans music (Roc Nation), streaming (Tidal, sold to Square for $350 million), champagne (Armand de Brignac, 50% sold to LVMH), cognac (D'Usse, sold to Bacardi), cannabis (Monogram), and venture capital (Marcy Venture Partners). Jay-Z has won 24 Grammys but his real talent is dealmaking — he turned a rap career into a diversified portfolio that generates wealth independently of music. Married to Beyonce. Combined net worth with his wife: $3.5+ billion.
