Stella Lefty’s “Boston” commands overwhelming trader consensus at 98.5% implied probability for the Billboard Hot 100’s No. 2 spot the week of September 19 because the track has held that exact position for multiple weeks on the strength of consistent multi-format radio airplay, streaming volume, and crossover appeal. Its country-pop blend continues to deliver steady gains without signs of fatigue, while Ella Langley’s dominant “Choosin’ Texas” locks down No. 1 and leaves little room for other titles to surge. Recent data show “Boston” maintaining top-five placement amid competition from tracks by Ariana Grande, Morgan Wallen, and Taylor Swift. An upset would require a sharp late-week acceleration in streams or sales for one of those contenders or an unexpected new release breaking into the upper tier before the tracking period closes.
