Taylor Swift

Net worth: $1.3 billion. Swift became a billionaire primarily through music — the only person on this list to do so. The Eras Tour grossed over $2 billion, making it the highest-grossing concert tour in history. She re-recorded her first six albums to own her masters after Scooter Braun acquired them for $300 million (a deal she called "my worst case scenario"). The re-recordings ("Taylor's Version") were so successful that streams of the originals dropped 90%. She has 14 Grammys, a Time Person of the Year title, and enough cultural influence to move elections.
