**BbY WOW by Karol G, Judeline, and rusowsky** leads with overwhelming market-implied odds because it has held the top spot on Spotify’s global daily and Billboard Global 200 charts for multiple weeks, posting record weekly streams above 42 million with consistent double-digit gains. The August 7 release from Karol G’s album *No Me Arrepiento de Sentir Tanto* benefits from dominant performance in Mexico, Spain, Colombia, and other key Latin markets, plus solid U.S. traction that pushed it into the Billboard Hot 100 top 10. Traders see few realistic upset paths before the September 25 chart lock, as competing tracks from established artists show far lower daily volume and no comparable recent momentum. A surprise major release or viral shift could theoretically intervene, but current streaming data leaves little room for another song to overtake it in the final days.
