Stella Lefty’s “Boston” commands the strongest market-implied odds at 73.5 percent, reflecting traders’ assessment of its recent streaming gains, playlist momentum, and promotional push that position it for a likely top-two finish on the Billboard Hot 100 for the week of September 12. Several unnamed tracks and the “Other” category sit at 50 percent, underscoring broad uncertainty about the exact runner-up. Ella Langley’s “Be Her” and “Choosin’ Texas,” alongside Taylor Swift’s “I Knew It, I Knew You,” register in the mid-teens, indicating measurable but secondary airplay and sales support. Lower odds on legacy cuts from Dolly Parton and Morgan Wallen’s “Been By Now” suggest limited recent velocity. The next chart update and final streaming tallies remain the key swing factors before resolution.
