The star's seventh studio collection Unapologetic is expected to top the Billboard 200 tally next week, making it a first for the Bajan performer.
Analysts predict the set could shift between 225,000 and 250,000 during its first week on sale in the United States, reports Billboard.
Industry insiders have claimed that, regardless of where the album lands on the chart, it will become her fastest-selling album yet.
So far, her best first-week sales were for 2010's Loud, which shifted 207,000 copies in the US upon its debut.
Meanwhile, Rihanna is on course to claim her fourth UK number one album with Unapologetic.
