Look What You Made Me Do was played more than eight million times on Spotify last Friday, more than any other song has achieved on its first day of release.
The music video starts with Swift crawling out of a grave and declaring her old self dead, portraying a hard-edged artist with nothing left to lose. In just one day, the clip racked up 39 million views, making it the most-viewed music video in a 24-hour period on the site.
Director Joseph Kahn celebrated the achievement on Twitter, telling Swift's fans "you are all amazing".
When asked who Swift is referring to, Antonoff told The Associated Press: "That's for her to tell you".
West also took aim at Swift on his track "Famous" previous year, in which he referred to the singer as a "b***h" and joked about sleeping with her.
