Match-fixing in football generates "hundreds of billions of euros per year" around the world according to Interpol.
Secretary General Robert Noble said revenues from illegal betting were "on the same scale as a Coca-Cola company".
He was speaking in Rome at a conference with FIFA on how to deal with the issue.
Mr Noble said that criminal networks were not only benefiting from the profits of match-fixing, but were also able to launder illegally-earned cash.
He said that no country was immune, citing Canada as an example.
The BBC reports some 200 delegates from 50 countries are attending the two-day conference.
Last year, FIFA announced a £17.5 million plan to crack down on match-fixing and illegal betting.
It said the money would be spent with Interpol on a 10-year anti-corruption programme to educate players, as well as referees and officials.
