In the announcement of her new album, Taylor Swift appears to call herself "The Chairman of the Tortured Poets Department".

Many have theorized that this implies there are other members of the department, and that the album will feature a number of collaborations with other artists.

This market asks who Swift would collab with if this theory is true. Songwriting credits also count as collaboration.

You can add names to the market yourself, and you'll get trader bonuses if people trade on them. I reserve the right to N/A options for any reason.

If The Tortured Poets Department includes bonus tracks which are released within 48 hours of the album, those count.

I may make minor updates to these resolution rules in the spirit of the question, so please let me know if you have any suggestions.
