CM Punk's first WWE world title reign in 12 years lasted only five minutes. Punk overcame a fantastic, grueling match with Gunther at WWE SummerSlam on Saturday only for Seth Rollins to spoil the evening.

WWE SummerSlam Night 1 was headlined by a World Heavyweight Championship bout between Gunther and CM Punk, but it was the returning Rollins who stole the show.

WWE delivered its biggest show of the summer with SummerSlam 2025, starting with a Night 1 that included multiple title changes and surprise celebrity interactions.
