Taylor Swift has added another chart milestone to her career as I Knew It, I Knew You debuts at No. 1 on the Hot 100. The song becomes her 15th leader on the ranking, extending a run of commercial success that has defined much of the past decade, according to Billboard’s historical data.
The latest chart results indicate strong support across streaming platforms, digital sales, and radio airplay. Industry tracking for the song’s opening week points to broad listener engagement, helping it secure the top position shortly after release.
The track has also drawn attention because of its connection to Toy Story 5, giving it visibility beyond Swift’s core audience. That crossover appeal appears to have contributed to the song’s strong launch and widespread discussion among fans.
