Stella Lefty’s “Boston” commands 79% implied probability for the Billboard Hot 100 #2 spot the week of August 29 because its sustained radio surge, streaming gains, and Northeast airplay dominance have kept the track in the top five for multiple weeks following its viral country-pop breakthrough. Recent Luminate data showed continued growth in radio reach and sales, reinforcing trader consensus that the single’s crossover momentum will hold strong against newer releases. Contenders such as the generic mid-tier options at 50% reflect uncertainty around competing debuts or holdovers, while major artists like Taylor Swift (9.5%) and Morgan Wallen (8%) sit far lower due to current chart trajectories and release timing. The next tracking-week update will determine whether “Boston” maintains or slips from contention.
