Stella Lefty’s “Boston” holds overwhelming trader consensus at 98.9% implied probability for the Billboard Hot 100’s No. 2 spot the week of September 26, driven by its consistent performance just behind Ella Langley’s record-setting “Choosin’ Texas.” The track recently claimed its first No. 1 on Country Airplay with 34.2 million audience impressions, reflecting strong radio growth across formats, steady streaming, and crossover appeal that has kept it locked at No. 2 on recent Hot 100 updates. Its long-chart run and promotional stability reinforce the market-implied odds. An upset would require a sharp surge from another track via major new data or a sudden drop in “Boston”’s metrics, both historically uncommon at this stage.
