ENTERTAINMENT NEWS - The star's sixth album, Reputation, has sold 1.04 million copies in the US since Friday, says Billboard magazine.
That puts her ahead of 2017's previous biggest-seller, Ed Sheeran's ÷, which has shifted 919,000 copies to date.
Reputation also becomes Swift's fourth album to sell a million copies in the space of a week, following 1989, Red and Speak Now.
In fact, only she and Adele have sold a million copies of any album in a seven-day frame since 2012.
Notably, both artists withheld their records from streaming services like Spotify and Apple Music - a move which drives committed fans to buy or download the album.
It has been rumoured that Reputation will be made available on those services later this week.
