CM Punk had a memorable rivalry with Matt Hardy's brother Jeff, but also faced Matt in singles and tag team matches in WWE.

The last time CM Punk and Matt Hardy shared a ring was in 2010, when they wrestled for NXT Season 1. Their last singles match against each other was in 2009, in a Beat the Clock Challenge on SmackDown.

Matt Hardy debuted on AEW television in March 2020 after leaving WWE. A match between them in AEW could blow the roof off of the arena.

Jon Moxley is another star that CM Punk has faced a few times in WWE, during Punk's rivalry with The Shield. Moxley, who went by the ring name Dean Ambrose in WWE, was gaining prominence when Punk's WWE career was coming to an end.
