**BbY WOW** by KAROL G, Judeline, and rusowsky holds overwhelming market-implied odds for the Spotify Global weekly #1 ending September 4, driven by its rapid ascent to the top of daily global tallies and a peak weekly stream count exceeding 19.9 million. The track, released in mid-August from Karol G’s album *No Me Arrepiento de Sentir Tanto*, surged on the strength of dominant Latin-market performance in Mexico, Colombia, Spain, and Peru alongside broadening U.S. traction, where it also claimed the Hot Latin Songs summit and displaced one of Karol G’s own prior releases. Its momentum reflects strong fan-driven streaming, viral appeal among Spanish-speaking audiences, and consistent daily gains that outpace competitors such as Malcolm Todd’s “Earrings” or older catalog tracks. An upset would require a dramatic late-week acceleration from a rival in the final daily updates, which remains unlikely given the current trajectory and established lead.
