**BbY WOW by KAROL G, Judeline, and rusowsky leads trader sentiment at 72% implied probability** for the Spotify Global weekly #1 ending September 4, 2026, thanks to its rapid late-August surge that has displaced prior frontrunners. The track, from Karol G’s August 7 album *NO ME ARREPIENTO DE SENTIR TANTO*, exploded after release, climbing to No. 1 on daily Spotify Global tallies and reaching No. 8 on the weekly chart (19.96 million streams) by late August, with particularly dominant performance in key Latin markets like Mexico, Colombia, Spain, Peru, and Ecuador alongside growing U.S. traction. Its momentum stems from strong streaming velocity fueled by Karol G’s established fanbase, the song’s viral TikTok-driven appeal (including an interpolation of a classic dance track), and high-profile production credits. This has allowed it to overtake tracks like Malcolm Todd’s “Earrings” and Justin Bieber and Nicki Minaj’s “Beauty and a Beat,” which now sit at much lower implied odds around 3–5%. With the chart week for September 4 still unfolding and the song holding recent daily peaks, traders see limited immediate competition capable of reversing its trajectory before lock.
