Taylor Swift’s *The Life of a Showgirl: The Encore* deluxe edition, released September 25 with four new tracks including “Patient Zero,” triggered a 619% unit surge to 173,000 equivalent albums the following tracking week, vaulting the project back to No. 1 on the Oct. 10 Billboard 200. That streaming-heavy spike, fueled by fan engagement and the album’s prior record-breaking run, underpins the market’s strong implied probability for the Oct. 17 chart. Sustained consumption from the new material positions it ahead of recent toppers like Miley Cyrus’ *Bass Persuades*, Olivia Rodrigo’s *you seem pretty sad for a girl so in love*, Ella Langley’s *Dandelion*, and Stray Kids’ *This & That*, though mid-October releases or late surges could still narrow the gap before chart lock.
