This market will settle to Yes if Boston by Stella Lefty is the #1 song on any Billboard Hot 100 chart dated in September 2026. Outcome sourced from Billboard.

Billboard typically updates the Billboard Hot 100 chart each Tuesday (with adjusted release schedules on some holiday weeks), reflecting data from the previous week (Friday-Thursday). Each Billboard chart is then dated Week of (date of the upcoming Saturday). Under this framework, the charts dated September 5, September 12, September 19, and September 26 would qualify.
