Even if you’ve never watched a second of a boxing match, you’re almost certainly familiar with the most famous catchphrase in the sport: “Let’s get ready to rumbleeeeee!“
Michael Buffer’s legendary, booming voice has filled countless arenas with those five words, delighting boxing fans around the world and electrifying the atmosphere before the first punch is thrown. But Buffer didn’t just become a beloved figure in sports — he parlayed that iconic line into a staggering fortune.
Today, Michael Buffer has a net worth of $400 million, built on smart business moves, global fame, and an iron grip on his intellectual property. Here’s how he made it happen.

Early Life and Struggles
Michael Buffer was born in Philadelphia on November 2, 1944. When he was only 11 months old, his parents divorced and he went to live with his foster parents. He enlisted in the Army during the Vietnam War, serving for three years. When he returned, he spent 15 years trying to launch an acting and modeling career, with limited success.
By age 38, Buffer knew something needed to change. He had always been a boxing fan, but he found ringside announcers were dull and predictable. He thought his charismatic personality could land him a job, so he embellished his resume to show more experience than he actually had. It worked — he hosted his first boxing gig in 1982, and within a year, he was announcing every match promoted by Bob Arum’s Top Rank on ESPN.
The Birth of a Legendary Catchphrase
As Buffer’s popularity grew, he realized a catchphrase could propel him to new heights — maybe even make him the most recognizable announcer in the world.
He experimented with several ideas at first:
- “Man your battle stations!” — fell flat.
- “Fasten your seatbelts!” — didn’t fire up the crowd.
Then inspiration struck.
Buffer recalled Muhammad Ali saying, “I’m so pretty, I’m ready to rumble. Rumble, young man, rumble.”
He also thought about a line from New York sportscaster Sal Marchiano: “We’re ready to rumble from Resorts International.”
Combining the two, Buffer created the now legendary:
“Let’s get ready to rumble!”
Skyrocketing Fame — And A Major Problem
Buffer’s catchphrase was an instant sensation. His career exploded:
- He became the exclusive announcer for fights held at Donald Trump’s casinos.
- He was hired by World Championship Wrestling (WCW) to introduce all main events until the league shut down in 2001.
- He landed cameos in movies like “Rocky Balboa,” TV shows like “South Park,” and video games like “Ready 2 Rumble Boxing.”
But with fame came a problem: Everyone was using his phrase without permission.
Commercials, TV shows, even other announcers echoed “Let’s get ready to rumble!” — without Buffer earning a dime.
The $400 Million Business Move
Enter Bruce Buffer — Michael’s half-brother (and future UFC octagon announcer). Interestingly, the two didn’t grow up together. They didn’t even meet until they were adults.
It wasn’t until Bruce’s father (who was also Michael’s biological father) saw Michael announcing boxing matches on TV that he realized the connection. He introduced the two, and they quickly bonded, especially over their mutual love for sports and entertainment.
Bruce pointed out that NBA coach Pat Riley had famously trademarked “three-peat,” and suggested Michael trademark his own phrase.
Michael took the advice — and it changed everything.
By trademarking “Let’s get ready to rumble!”, Buffer secured the rights to his five-word masterpiece. Any time the phrase is used in media, advertising, merchandise, or video games, Buffer either gets paid directly or licenses it for a fee.
Over the years, variations have popped up with Buffer’s blessing, including:
- Progressive Insurance: “Let’s get ready to bundle!”
- Kraft Cheese: “Let’s get ready to crumble!”
- Ready 2 Rumble Boxing video game series
- Multiple movie trailers and promotional events
Thanks to licensing deals and trademark enforcement, Michael Buffer was earning an estimated $5 million per year at the height of his popularity in the late 1990s and early 2000s.
To date, Michael has earned hundreds of millions of dollars licensing his famous catchphrase. He earned $100 million licensing the phrase for the “Ready 2 Rumble” video game franchise.
Even today, when Buffer steps into the spotlight to deliver his five iconic words, he typically earns between $25,000 and $100,000 per event — and for especially high-profile appearances, his fee has reportedly reached as much as $1 million.
Michael Buffer Today
Buffer occasionally steps back into the spotlight. He introduced playoff games during the 2022 NFL postseason, and made appearances at major events like Jake Paul’s boxing matches in 2023.
Buffer has mentioned plans to sell the rights to his catchphrase upon retirement. Given the value he’s created, insiders estimate it could fetch a huge price from a brand or entertainment group eager to capitalize on its global recognition.
From a struggling actor to a centi-millionaire entrepreneur, Michael Buffer’s story is a masterclass in creativity, timing, and business savvy. He didn’t just find his voice — he protected it, scaled it, and turned it into a fortune.
And whenever he finally retires, one thing is certain: Michael Buffer — and his iconic five words — will always be ready to rumble.
