Taylor Swift’s “Patient Zero,” the lead single from the Sept. 25 release of *The Life of a Showgirl: The Encore*, opened with record-setting streams and has held the top U.S. Spotify daily position for more than a week while ranking No. 2 globally. Its first full U.S. weekly tally exceeded 19 million streams, far ahead of catalog tracks and recent competitors such as Karol G’s “BbY WOW” and ADÉLA’s “Nicole Kidman.” Trader consensus at 98% reflects this sustained dominance and the absence of major new releases capable of overtaking it by the Oct. 9 chart lock. An upset would require an unforeseen late-week surge from another track or a sharp drop in Swift’s plays, both considered low-probability scenarios given current momentum.
