Australian Kaylee McKeown and American Regan Smith went one-two in the 200m backstroke, just as they did in all three backstrokes at the 2023 Worlds, both backstrokes at the 2024 Olympics and in the 100m back earlier at these worlds.

American star Katie Ledecky won her seventh world title in the women’s 800-meter freestyle on Saturday, fending off the challenges of Canadian sensation Summer McIntosh and Australia’s Lani Pallister.

In other events, Gretchen Walsh became the first American woman to ever win gold at the world championships in the 50m butterfly. Regan Smith and Claire Curzan took silver and bronze, respectively, in the women's 200m backstroke. Jack Alexy's bronze in the men's 50 freestyle was his third medal of the 2025 world championships.
