**BbY WOW** by KAROL G, Judeline, and rusowsky holds overwhelming market-implied odds near 99% for the weekly Spotify Global #1 around October 16 because it has dominated daily and weekly charts for weeks. The track logged its fifth consecutive week at No. 1 on the Billboard Global 200 with roughly 36 million streams in recent tracking periods, outpacing challengers by wide margins and extending a record run atop Spotify’s global daily ranking. Strong Latin radio airplay gains, sustained TikTok momentum, and the song’s placement on Karol G’s latest album reinforce its streaming consistency across regions. Traders see limited realistic upset paths, such as an unexpected blockbuster debut from a major artist that could briefly close the gap, though current data shows no such threat materializing before the chart locks.
