Dominic Fike’s “Babydoll” dominates trader sentiment for the #2 Spotify song of 2026 at an 84% implied probability, fueled by its early-year TikTok-driven resurgence that propelled the 2018 track to billions of streams, a February 2026 re-release with a new music video, and a late-October No. 1 on the Pop Airplay chart. This catalog revival, amplified by radio airplay gains and strong global chart placement, has positioned it ahead of newer contenders and other resurgences such as Djo’s “End of Beginning.” Traders appear to weigh the song’s sustained streaming momentum and historical precedent for viral catalog hits against the risk of late-year shifts from frontline releases or holiday tracks as year-end totals lock in.
