Caeleb Dressel won three golds in one session to take his overall tally to six at the 2019 World Championships.
Dressel, 22, defended his 50m freestyle and 100m butterfly titles and helped the US win the 4×100m mixed freestyle relay with a new world record.
He won the 50m freestyle final in 21.04 seconds, with Britain's Ben Proud just 0.1 outside the medals in fifth.
Dressel then won the 100m butterfly in 49.66, a time second only to the world record he set in the semi-finals.
His time of 49.50 bettered the mark set by compatriot Michael Phelps - the most decorated Olympian of all time - in the 2009 World Championships by a third of a second.
Proud, 24, won 50m freestyle bronze in 2017 and qualified third-fastest for the 2019 final, but Dressel took gold 0.41 ahead of Brazil's Bruno Fratus and Kristian Gkolomeev of Greece.
"I knew what it would take to get on to the podium and I was exactly right," said Proud. "I just didn't quite execute the race as I would have hoped."
Dressel won the 100m butterfly final ahead of Russia's Andrey Minakov and South African Chad le Clos, with Britain's James Guy, who claimed bronze in 2017, coming seventh despite a season's best time of 51.62.
Along with Zach Apple, Mallory Comerford and Simone Manuel, Dressel won gold in the 4×100m mixed freestyle relay ahead of Australia and France.
They knocked 0.20 off the world record to set a new mark of 3:19.40.
Elsewhere, Britain's Anna Hopkin set a personal best of 24.34 in the women's 50m freestyle semi-finals, to qualify sixth-fastest for Sunday's final.
Highlights will be shown online and on BBC Two on Sunday (15:30-17:00 BST).
