In October Hurd participated in the Worlds Team Selection Camp. During the competition a shaky performance caused her to place fourth in the all-around behind Biles, McCusker, and McCallum, fourth on uneven bars, fifth on vault, sixth on balance beam, and seventh on floor exercise. The following day she was named to the team to compete at the 2018 World Championships alongside Biles, McCusker, Grace McCallum, Kara Eaker, and alternate Ragan Smith. During qualifications, Hurd qualified to the all-around final in second place behind Biles, the floor exercise final in fourth place, and the uneven bars final in fifth place. The US also qualified to the team final in first place. During the team final Hurd competed on vault, uneven bars, and floor exercise. She contributed scores of 14.633, 14.433, and 12.966 respectively towards the USA's team total. USA won gold with a score of 171.629, 8.766 points ahead of second place Russia, beating previous margin of victory records set in the open-ended code of points era at the 2014 World Championships (6.693) and the 2016 Olympic Games (8.209).
