American swimmer Bobby Finke set a new world record in the men's 1500m freestyle with a time of 14:30.67, surpassing Sun Yang's previous record. Australian swimmer Kaylee McKeown achieved historic success by winning the women’s 200m backstroke, setting a new Olympic record of 2:03.73, and becoming the first woman to win back-to-back doubles in the backstroke at the Olympics. McKeown's victory marked her fourth individual Olympic gold, making her the first Australian athlete in any sport to achieve this feat. Additionally, Léon Marchand of France narrowly missed setting a world record in the men's 200m individual medley, capturing gold with an Olympic record time of 1:54.06. McKeown also secured a bronze in the 200m individual medley due to American Alex Walsh's disqualification.
