Taylor Swift’s “Patient Zero” holds a 95% market-implied probability of topping the Billboard Hot 100 for the week of October 24 because its September 25 deluxe-edition debut on The Life of a Showgirl: The Encore produced the largest opening-week streaming and sales totals of the tracking period, dethroning Ella Langley’s record 24-week run with “Choosin’ Texas.” The track’s 34.5 million first-week streams, 65,000 sales, and star-studded music-video premiere at the 2026 MTV VMAs fueled sustained radio and consumption gains into the second chart week. Early forecasts already project another dominant frame, aided by bundled physical sales and playlist momentum. An upset would require an unprecedented mid-cycle collapse in streams or a surprise major release that captures disproportionate radio and sales share before the tracking window closes.
