...Ready for It?

"...Ready for It?" is a song by the American singer-songwriter Taylor Swift from her sixth studio album, Reputation (2017). She wrote the song with its producers: Max Martin, Shellback, and Ali Payami. An electro, electropop and industrial pop song, "...Ready for It?" incorporates elements of dancehall, tropical house, hip-hop, and trap. It features Swift rapping and singing over heavy synthesizers, bass drops, and programmed drums. Lyrically, the track uses criminal imagery such as bank heist and ransom to depict lust and infatuation in a newfound romantic connection.

Swift premiered "...Ready for It?" during an ESPN college football match on September 2, 2017; the following day, Big Machine Records released the song for digital download. The single was released to US radio as the second single from Reputation on October 24, 2017. Music critics generally described the production of "...Ready for It?" as anthemic and considered it a better single choice than Reputation's lead single "Look What You Made Me Do". While most reviews praised the production elements, several regarded the track as generic and indiscernible from mainstream trends.

The single both peaked within the top 10 and received platinum certifications in Australia, Canada, New Zealand, the United Kingdom, and the United States. The accompanying music video, directed by Joseph Kahn, features a dark, futuristic aesthetic and references sci-fi franchises. It depicts two versions of Swift dueling each other: a black-hooded human version and a mechanized, robotic version. Swift performed "...Ready for It?" live as the opener on the Reputation Stadium Tour (2018) and the first song of the Reputation act on the Eras Tour (2023–2024).
