“This has definitely been the most exhausting, all-encompassing, but most joyful, most rewarding, most wonderful thing that has ever happened in my life, this tour,” Swift said, according to footage from the audience posted on social media.

“The celebration of the 100th show for me means this is the very first time I’ve ever acknowledged to myself and admitted that this tour is going to end in December,” she continued. “That feels so far away from now, but then again, it feels like we just played our first show on this tour. Because you have made this so much fun for us that we wanted to do 100 shows — 150-something shows that we have on the whole tour.”

Since the tour’s first stop in Glendale, Ariz., Swift has created a cultural phenomenon and solidified her pop dominance, performing in 17 states and 12 countries so far across North America, South America, Australia, Asia and Europe.

The 3½-hour-long show became the highest-grossing tour of all time by surpassing $1 billion in December, and it has broken attendance records at multiple stadiums. The film version became the highest-grossing concert film ever, according to the Grammy Awards.

Swift kicked off the European leg of her tour last month and will perform there through August. She will return to the United States briefly in October and November, with concerts in Miami, New Orleans and Indianapolis.

The tour’s final announced dates are in Toronto and Vancouver at the end of November and beginning of December, respectively. The last scheduled tour date is Dec. 8, five days before Swift’s 35th birthday.

“This tour has really become my entire life. It’s become — it’s taken over everything. I think I once had hobbies, but I don’t know what they were anymore, because all I do when I’m not onstage is sit at home and try to think of clever acoustic song mashups and think about what you might want to hear,” Swift said at Thursday’s show. “When I’m not on the stage, I’m dreaming about being back on the stage with you guys.”

She made the comments before playing the 10-minute version of “All Too Well,” one of her most celebrated songs. Dressed in the red sequined costume that corresponds with her “Red” album, on which the song appears, Swift smiled as she acknowledged the lengths to which fans have gone to attend the concert.

“You have done so much to be with us, right? You’ve made plans so far in advance. You planned what you were going to wear, you memorized lyrics, you got yourselves here, you figured out parking, you figured out transportation,” Swift said.

“I want to spend the 100th show just thinking about that and living in this moment with you and being here with you. And just know that I appreciate every single ounce of effort that you put in to being with us.”
