Bill Walters used to be a professional poker player before using his skills as a professional sports punter instead. Over nearly four decades, Walters has bet more money than anyone else in history and continued a winning streak that has earned him hundreds of millions of dollars. He’s living proof that sport betting is a game of skill. Like poker, Walters explains that winning sports punters have to analyze information then calculate risk and potential profits. In an interview with CBS News, Walters described his biggest and most audacious bet of all time. The New Orleans Saints were playing the Indianapolis Colts at the Super Bowl in 2010 and the consensus was that New Orleans were the underdogs. Walters analyzed all the information he had and discovered that it actually favored New Orleans as the most likely winners. He looked at the odds, calculated the risk and potential profit then decided to bet big. Walters bet $3.5 million on the supposed underdogs and New Orleans didn’t let him down. They defeated the colts 31–17 to win their first ever Super Bowl.

How much did Bill win?

No one knows, but given that the Saints were the underdogs, we’re sure he made a pretty penny off this single bet.
