Grand Slam Mexico will take place two months later than it did last year, a decision likely influenced by the 2026 FIFA World Cup. The football extravaganza will be held, in part, in Mexico from mid-June to mid-July, which has resulted in CMLL tweaking their schedule to hold shows in Mexico City, Puebla, and Guadalajara every day of the week, thus making it unlikely for AEW to hold Grand Slam in June. The show will now be part of AEW’s build to All In later in August, and will come just two weeks after AEW Redemption, being held in Montreal on July 26.

The first edition of Grand Slam Mexico proved to be important to both AEW and CMLL, as it kick-started a month-long feud between MJF and Mistico after the latter defeated MJF by DQ. Their issues would culminate at CMLL’s 92nd Aniversario in September, where Mistico would defeat MJF in a Mask vs. Title match to claim the CMLL World Light Heavyweight Championship.
