Wrestling / Grand Slam Champion

In Professional Wrestling, a "Grand Slam Championship" is not a championship in and of itself. Rather, it's a special achievement given to wrestlers who have won at least four certain titles in their career. Currently, WWE, TNA/Impact Wrestling, Ring of Honor, New Japan and World Wonder Ring ST★RDOM are major promotions with a Grand Slam methodology^note One could think of those first 4 promotions and their world titles as a Grand Slam Championship of men's professional wrestling (except ROH would now be replaced by AEW, especially since they now own ROH), though no one has been able to pull this off yet. AJ Styles has come the closest, winning the world titles in WWE, TNA, and NJPW, though other minor promotions have their own Grand Slam methodologies.

See also Triple Crown Champion, a feat which in most cases is required in order to achieve the "Grand Slam", usually involving three Championships that are required for a Grand Slam.

WWE has absorbed the history of WCW and ECW, however neither promotion had four titles eligible for a Grand Slam. If the WCW World Television Championship was recognized as eligible, all WCW Triple Crown Champions except Goldberg and Bret Hart would also be Grand Slam Champions. Booker T would be the only man to have earned Grand Slam Champion status in both WCW and WWE, and would be the only man to have earned both without counting the same championship for both. AJ Styles is the only man to have earned the Grand Slam Champion status in both TNA and WWE. Kevin Owens and Finn Bálor are the only Grand Slam Champions who are not considered Triple Crown Champions due to not winning the WWE Championship, but the Universal Championship instead. Seth Rollins and Roman Reigns are the only Grand Slam Champions since the establishment of the modern format to win newer versions of World Titles (the Universal Championship and the new World Heavyweight Championship introduced in 2023) that do not qualify as requirements for WWE's Triple Crown for some reason (Rollins has won both, and was in fact the inaugural holder of the newest title).

On March 1, 2021, NJPW retired its IWGP Heavyweight and Intercontinental championships, merging them into the new IWGP World Heavyweight Championship. NJPW has not announced whether it will establish a new Grand Slam, even though it added the US-exclusive Strong Openweight Championship^note US-exclusive in that it's defended only on its US shows later that year and the NJPW World Television Championship in 2023.

All Elite Wrestling

AEW is as of this writing just shy of its 4th anniversary, and booker/CEO Tony Khan doesn't seem to like frequent title changes, so this hasn't come into play yet. However, AEW does have 3 singles titles and 2 tag team titles, so a Grand Slam Championship would certainly be possible and would consist of:

• The AEW World Championship
• The AEW International Championship (formerly the AEW All-Atlantic Championship)
• The AEW TNT Championship
• Either the AEW Tag Team Championship or the AEW Trios Championship

So far no one has been able to win more than two of those titles. A women's grand slam, or even a women's triple crown, wouldn't be possible as AEW only has two women's belts. However, AEW now owns Ring of Honor^note Technically AEW doesn't own it, Tony Khan does, though in practice it's the same thing, while the two companies are being ran as separate promotions (or at least as separate TV shows) there's lots of cross-pollination between the two and ROH champions frequently appear on AEW programming. AEW has more or less absorbed ROH's history into its own canon, similar to what WWE did when they bought WCW and ECW, so a hypothetical AEW-ROH combined Grand Slam Championship would look like:

• The AEW World Championship
• The ROH World Championship
• The AEW Tag Team Championship
• The ROH Tag Team Championship
