The 2018 UCI BMX Supercross World Cup finals would crown the Elite Men and Women's champions after the 7 month World tour would wrap up in Santiago del Estero, Argentina. Niek Kimmann, Joris Daudet, and Sylvain Andre were all in the title hunt on the Mens side. For Elite Woman, Laura Smulders held a firm lead in points over Saya Sakaibara, and Judy Baauw, but it would come down to the last weekend to crown the champions.
