In January 2019, Adam Page signed with upstart promotion All Elite Wrestling (AEW). Page was scheduled to face Pac at AEW's inaugural event Double or Nothing after a confrontation between the two at an AEW press conference, but the match was later cancelled due to "creative differences". Instead, Page was the surprise final entrant in the Casino Battle Royale at Double or Nothing, where he last eliminated MJF to win and get an AEW World Championship opportunity. However, at All Out on August 31, Page was defeated by Chris Jericho in a match to crown the inaugural AEW World Champion. On the premiere episode of "Dynamite" on October 2, Page was defeated by a returning Pac, but was able to emerge victorious over him in a rematch at Full Gear on November 9.
