Forbes estimates Paul McCartney’s fortune at at least $1.4 billion, making him the world’s third-richest musician after Jay-Z and Taylor Swift. His largest asset is MPL Communications, a publishing company valued at $250 million or more that owns thousands of songs, including Buddy Holly’s catalog. McCartney founded MPL in 1969 and built its holdings over decades, while also pursuing ownership of music rights he said the Beatles had initially lost.
