Stella Lefty’s “Boston” commands the highest market-implied odds for the No. 2 slot on the Billboard Hot 100 dated September 26 because it has held that exact position on recent charts behind Ella Langley’s record-setting “Choosin’ Texas.” The track’s sustained momentum stems from TikTok-driven virality, crossover radio airplay on country and pop formats, and consistent streaming and sales data that have kept it ahead of other contenders. Traders see limited immediate threats from tracks like Taylor Swift’s “I Knew It, I Knew You,” Ariana Grande’s “hate that i made you love me,” Morgan Wallen’s “Been By Now,” or Langley’s additional entries, given current trajectory and historical chart patterns. The next tracking periods and official chart updates will determine whether any late surges alter the ranking.
