Taylor Swift's music as a reputation for being very standard musically. Indeed, many of her songs use the standard pop music chord progressions and are in major keys. I read something from someone on Reddit who said that Look What You Made Me Do is her only song in a minor key. Maybe this was a few years ago, because I am aware that "no body, no crime" and "Vigilante Shit" are also in minor keys.

This market will resolve to the number of Taylor Swift songs which I believe to be in minor keys by July. 

Note that many of her songs have verses that are in minor keys or seem to be in minor keys and then the choruses are major. I am only counting a song as being in a minor key if there is a V chord with a raised third. 

Disclaimer that I follow common-sense spirit of the market and my own intention rather than exact wording in the event that there is a dispute that cannot be resolved by examining the text of the market. 

This market was created to give people an incentive to tell me if there are any other Taylor Swift songs in minor keys.
