Michael Buffer: $400 Million
In a surprising turn of events, in-ring announcing has been a highly lucrative profession for Michael Buffer, with a net worth exceeding $400 million. Buffer is best known for his trademarked catchphrase, "Let's get ready to rumble." As the ringside announcer for Bob Arum and Top Rank on ESPN in the 1980s, Buffer gained significant exposure, and his catchphrase became an integral part of pre-fight ceremonies. The trademark and licensing of his slogan have continually filled his coffers.
