**"BbY WOW" by KAROL G, Judeline, and rusowsky leads trader sentiment at 74% implied probability** for the global Spotify weekly #1 ending September 4, 2026, driven by its explosive recent chart trajectory and daily #1 surge. The track posted a massive weekly gain to reach No. 8 globally (19.96 million streams in one tracked period) and climbed to No. 1 on daily tallies, fueled by strong Latin market performance in Mexico, Colombia, and Spain alongside growing U.S. traction (over 4.3 million U.S. streams in the latest week). Its streaming momentum, supported by Karol G’s established fanbase, the collab’s viral appeal from her *No Me Arrepiento de Sentir Tanto* album, and consistent gains across platforms, positions it to lock in the weekly crown over longer-running or stabilizing tracks. Lower-odds contenders such as Justin Bieber and Nicki Minaj’s “Beauty and a Beat” (recently displaced at daily No. 1), Malcolm Todd’s “Earrings,” Steve Lacy’s “Oh Yeah?,” Tame Impala’s “Loser,” Dominic Fike’s “Babydoll,” Katy Perry’s “The One That Got Away,” and others like Shakira/Burna Boy or BTS reflect steadier or declining streams without comparable late-week acceleration. Key catalysts ahead include final daily updates through early September that will determine whether the Latin hit secures the weekly top spot.
