Starting his season strong with a bronze medal at 2017 CS Finlandia Trophy, Rippon then went on to win silver medals in both of his Grand Prix assignments, 2017 NHK Trophy and 2017 Skate America. His placements at these events qualified him for his second Grand Prix Final. During his free skate at Skate America, Rippon fell on his shoulder while executing a quad lutz, but he was able to continue with his performance without stopping. At the 2018 U.S. Championships, Rippon placed 4th.
