Intercontinental, and Hardcore titles. Following WrestleMania 31 in 2015, WWE (which four years earlier ended the brand extension and unified several titles before that) established an updated version of the Grand Slam consisting of the four then-active men's titles in WWE: the WWE World, Intercontinental, United States, and WWE Tag Team Championships. Thirteen wrestlers have been recognized as Grand Slam winners under these new parameters (including five who were already recognized as Grand Slam winners under the original guidelines). The brand extension was re-established in 2016 and WWE indicated that two new championships that had been introduced, the Universal Championship and the SmackDown Tag Team Championship, count as acceptable substitutes for their counterpart titles (WWE Championship and WWE Tag Team, now Raw Tag Team, respectively) as part of the Grand Slam. Chris Jericho completed the original format the fastest, completing it in 728 days between December 1999 and December 2001, while Kurt Angle completed the modern format the fastest, completing it in 966 days between February 2000 and October 2002. On February 21, 2021, WWE acknowledged The Miz as the first wrestler to complete the Grand Slam twice under the revised 2015 format after winning his second WWE Championship. Seth Rollins would become the second two-time Grand Slam Champion by winning the WWE United States Championship a second time in October 2022. Triple H, Chris Jericho and Christian have each completed the original Grand Slam format twice, while Jeff Hardy has completed it three times, although it is unknown if WWE officially recognises these achievements.
