Taylor Swift’s “Patient Zero,” released September 25 as the lead single from the surprise “The Life of a Showgirl: Encore” expansion, has driven overwhelming trader consensus at 95.7% implied probability. The track posted the biggest U.S. Spotify debut of 2026 with 6.125 million streams on day one and held the top daily spot with 2.34 million streams the following day, far outpacing steady competitors such as Ella Langley’s “Choosin’ Texas” and Malcolm Todd’s “Earrings.” Four new Swift tracks simultaneously claimed the top U.S. positions, fueled by fan streaming surges and the song’s VMAs video premiere. While an upset remains theoretically possible if post-hype streams decline sharply before the weekly chart locks, the scale of the opening and sustained momentum make a reversal unlikely.
