According to the search results, the following belts are on the line for the Canelo vs Charlo fight:

• Canelo Alvarez will defend his four 168 lb belts, which are the WBA (Super), WBC, IBF, and WBO super middleweight titles.
• Jermell Charlo will move up from 154 lbs to challenge Canelo, and he will be risking his four titles in that weight class.

Its worth noting that once Charlo climbs between the ropes, he will be stripped of the WBO super welterweight title, which will be on the line in a fight in October between Tim Tszyu and Brian Mendoza.
