Since we launched this chart in late October, Republic has pretty much owned it. Monte Lipman and his squad have been riding an extended hot streak fueled by consistent sellers (Pop Smoke, The Weeknd, Post Malone, Taylor Swift’s folklore) and jacked up by one big new release after another: Ariana Grande’s Positions in November, Tay’s evermore in December and Morgan Wallen’s Dangerous (Big Loud) in January.

All that heavy ordnance lifted Republic to a 35% share in total activity for the week ending 1/14, which the company has nearly equaled a week later, with 31%. IGA, meanwhile, has picked up two percentage points to finish with 18%, as the two UMG labels once again slice off roughly half of the marketshare pie. It just doesn’t seem fair. But like the Kansas City Chiefs and the Tampa Bay Bucs, they’ve fought off every challenge. Impressive.

Our Top 100 Weekly Marketshare Chart, which is determined solely by volume, shows the relative performance of the major labels by percentage at the top tier of the overall business.
