UFC 217 was the first UFC event to feature three title changes on one card.
Held at Madison Square Garden in New York City on November 4, 2017, UFC 217 produced three championship upsets. Georges St-Pierre defeated Michael Bisping for the middleweight title, T.J. Dillashaw stopped Cody Garbrandt to reclaim the bantamweight championship, and Rose Namajunas defeated Joanna Jędrzejczyk for the strawweight belt.
The event was historically notable because all three title fights ended with a new champion. St-Pierre’s victory also marked his return to competition after a four-year absence and made him a UFC champion in a second division.
UFC 205 is sometimes mentioned in similar discussions because it featured multiple major title fights and was the UFC’s first Madison Square Garden event. However, UFC 217 holds the specific record for the first card with three championship changes.
