With the WBA, WBO, WBC, IBF and IBO organizations you would think there would be numerous dual champions but there are only four unless you count Terence Crawford who had four before stepping up to welterweight.

Heavyweight champion from the UK Anthony Joshua with just twenty fights holds the WBA & IBF titles. American Keith Thurman holds welterweight titles in the WBC & WBA. Ryan Bennett of the UK holds the WBA & IBF titles at bantamweight.

The only boxer holding three titles is middleweight champion Gennady “GGG” Golovkin.

In Thailand there are two minimum world champions. There is Chayaphon Moonsri at 49-0 holding the WBC and Thammanoon Niyomtrong 16-0 the WBA title. They could be meeting in 2018.
