Taylor Swift’s “Patient Zero” commands near-certain trader consensus for the Billboard Hot 100 dated October 24 because it already logged two weeks at No. 1 following its debut on the deluxe edition of *The Life of a Showgirl: The Encore*, released September 25. The track opened with 34.5 million U.S. streams, strong radio impressions, and 65,000 sales in its first tracking week, then held the summit despite a steep drop in consumption as Swift added a piano version, limited vinyls, and an expanded video to sustain buyer interest. Its momentum displaced Ella Langley’s record-setting “Choosin’ Texas” and placed three other new tracks inside the top five, illustrating the broad fan engagement and multi-format strategy that typically locks in chart dominance. An upset would require an unusually sharp second-week decline plus a competing release posting outsized gains in the final days of the tracking period.
