The defending champion Mensur Suljović lost 4–11 against Gary Anderson in the semi-final; a rematch of the 2017 final.

Anderson went on to win his first Champions League title by defeating compatriot Peter Wright 11–4 in the final.

It was also Anderson's 3rd major title of the season after winning that year's UK Open and World Matchplay.

A noticeable controversy was the walk-ons before the group match between Simon Whitlock and Peter Wright, where Wright's walk-on music, "Don't Stop the Party" by Pitbull, was played when Whitlock walked onto the stage, instead of his own track, "Down Under" by Men at Work.

The top 7 players on the PDC Order of Merit following the 2018 World Matchplay qualified.
