The gold went to American Grant Shoults.
"I'm very, very excited. We have an awesome US team. Super excited to start it off with a bang.... and I know that for the US team there's a lot more coming, so, very excited."
On the women's side, Britain's Rosie Rudin has set a new world junior record in the girls' 400 metre individual medley.
"I'm so shocked right now. I wasn't expecting to go that fast. I mean I did a good morning swim for me, but I still didn't expect to go that fast."
Australia has been dominant in both of the evening's relays, winning the 4X100 freestyle.
The girls team took the 4X200 meter freestyle gold.
