Grand Slam was AEW's New York City debut and marked the first AEW event to be held in its entirety within a stadium. Until All In London in August 2023, it was AEW's most attended event with 20,177 fans in attendance. The event was highly praised by fans and critics with particular praise towards the Kenny Omega vs. Bryan Danielson match, which received a 5 star rating from wrestling journalist Dave Meltzer. The Rampage broadcast was also notable for CM Punk's first wrestling match on cable television since facing Billy Gunn on the January 20, 2014, episode of WWE Raw.
