CM Punk has been at the top of his game ever since he came back to WWE. “The Best in the World” is a lock to compete at the upcoming two-night WWE SummerSlam event in August. Interestingly, it is the same event that featured his return to singles in-ring action last year after recovering from his triceps injury.
Punk has made a lot of rivals leading up to this year’s grand summer spectacle. With that in mind, let’s look at five potential opponents for “The Cult of Personality” at SummerSlam 2025.

AJ Styles

AJ Styles is one marquee name that CM Punk has not battled after achieving main event status. Moreover, there has been a reported beef between the two individuals for years. This could come head-to-head in an epic clash between two top superstars in a blockbuster match. Furthermore, it will be the first-ever match, making it a top addition for the WWE SummerSlam 2025 card.
Dominik Mysterio

Dominik Mysterio was tormented by CM Punk when he was a kid on WWE television. He was also the first WWE superstar Punk faced in a non-televised singles match. With Dirty Dom holding the WWE Intercontinental title at the moment and having a beef with Punk, it could be enough reason for them to square off in a title match at SummerSlam.

Roman Reigns

CM Punk has taken shots at Roman Reigns ever since returning to WWE. Punk was partially at fault for Reigns’ partnership with Paul Heyman imploding. The OTC could come back to reignite the WrestleMania 41 feud with The Second City Saint. This could lead to an explosive yet marquee showdown at the historic SummerSlam taking place in New Jersey this year.
Seth Rollins

Seth Rollins has continued to be a major roadblock in CM Punk’s path in WWE. From snatching away his best friend, Paul Heyman, and WrestleMania moment to denying him top opportunities, it has been nothing short of a heated rivalry. With both individuals having one singles win over each other, SummerSlam could decide the final victor in this captivating feud.
