Post Malone's last two albums, Beerbongs & Bentleys and Hollywood's Bleeding, did 461K and 489K, respectively, in their first week.
Post's latest album Twelve Carat Toothache, will do nothing close to that.
HitsDailyDouble projects Posty's fourth album will do between 110K to 135K first week and will battle with fourth week Bad Bunny for number one on the album chart.
That's well below the initial predictions of 250 -275K and continues a string of rather disappointing first-week openings for A-list artists.
Post did very little promo for the album, which may have contributed to its soft opening.
Malone's albums tend to sell big well beyond their first week; all three of his previous albums have gone 5x platinum.
But he's starting in a hole this time.
