On August 15, 2016, the TNA King of the Mountain Championship was once again retired when Lashley unified the title into his TNA World Heavyweight Championship. In a March 26, 2018, article on the Impact Wrestling website, the eligibility of the Impact Grand Championship, which replaced the King of the Mountain Championship, as a Grand Slam title was confirmed. However, on June 4, 2018 during a press conference Austin Aries unified the Grand Championship with the World Championship. Thus any future Grand Slam winners will be limited to those who had already held either the Legends/Global/TV/King of the Mountain title or Grand Championship.
