The mixed 4 × 50 metre freestyle relay event at the 2024 World Aquatics Swimming Championships (25 m) was held on 13 December 2024 at the Duna Arena in Budapest, Hungary.
Records Prior to the competition, the existing world and championship records were as follows.
Background France, the reigning world record holders, did not enter a team despite returning three legs from their 2022 victory. That left Australia, the USA, Italy, and Neutral Athletes B team as the likely contenders. Australia raced without Kyle Chalmers and Emma McKeon but leaned on Isaac Cooper and Alexandria Perkins. The U.S. introduced Gretchen Walsh and Kate Douglass to a new lineup anchored by Jack Alexy and Chris Guiliano. Italy returned with a strong male trio—Alessandro Miressi, Leonardo Deplano, and Lorenzo Zazzeri—supported by the rising Sara Curtis. The Neutral Athletes B team featured the Russian athletes Arina Surkova and Egor Kornev. Hungary relied on Nándor Németh and Szebasztián Szabó, though lacked depth on the women’s side.
SwimSwam wrote that predicting the winners of the mixed relays was "nigh impossible" due to the amount of variables. They predicted USA would win, Australia would come second and Italy would come third.
Results Heats The heats were started at 9:02.
