Billboard reports that the song -- the lead release from Swift's new album "Reputation" -- is poised to make a huge debut at No. 1 on next week's Hot 100 chart. "Despacito" currently holds the top spot.
Billboard said the song could top 400,000 downloads, setting a new record for the best sales week of 2017.
In addition to debuting on top of the Billboard Hot 100, Swift's song could top the Streaming Songs chart too, and could even surpass the record for one-week streams by a woman. In 2015, Adele set that record when "Hello" racked up 61.6 million streams in its first week.
