This question resolves by which artist's album is listed on Wikipedia as having sold the most in 2024.

Taylor Swift and Adele have dominated album sales in the US since 2009. Both Swift and Adele are engaged in performances until November 2024 - Swift with her Eras Tour, and Adele with her concert residency in Las Vegas.

Will an album by Taylor Swift make the most sales in the United States in 2024?

Note: The Wikipedia list includes any albums sold, so for example, an album released in 2023 made by Taylor Swift that becomes the best selling album in 2024 would still count as a YES for this question.
