**BbY WOW by KAROL G, Judeline, and rusowsky** holds a dominant 98% market-implied probability for the top spot on the Spotify global weekly chart ending September 25 because the track has led Billboard’s Global 200 and Global Excl. U.S. charts for a second consecutive week with roughly 42.5 million streams in the most recent tracking period. The collaboration benefits from Karol G’s established Latin-pop fanbase, consistent week-over-week streaming gains, and broad international traction across Latin American markets and beyond. Trader consensus reflects this sustained momentum and the absence of comparable challengers in current data. Realistic upset scenarios would require a late-week viral spike or major promotional push for a track like Earrings by Malcolm Todd or a catalog resurgence from older releases, though such shifts appear unlikely given the current gap in daily and weekly streaming volume.
