Triple H's next appearance came at the 2018 Elimination Chamber event for the Raw contract signing of Ronda Rousey. During the segment, Triple H confirmed that there were no special stipulations in Rousey's contract, but she would have her debut match at WrestleMania 34. Before Rousey signed her contract, Kurt Angle brought up the incident from WrestleMania 31 where Rousey embarrassed The Authority and said that Triple H and Stephanie were now glad to own Rousey so they could manipulate her. This led to Rousey putting Triple H through a table and Stephanie slapped Rousey. Stephanie then retreated and Rousey signed the contract. The next night, the four had a segment to apologize and it ended with Triple H attacking Angle. The following week, Angle revealed that although Triple H and Stephanie were WWE executives, they also had contracts to compete as wrestlers. Angle reminded Triple H of his warning from after Survivor Series, and he scheduled himself and Rousey to face Triple H and Stephanie at WrestleMania 34 in a mixed tag team match. At WrestleMania, Triple H and Stephanie lost to Angle and Rousey after Stephanie submitted to Rousey's armbar. Triple H lost to John Cena at the Greatest Royal Rumble in Jeddah, Saudi Arabia.
