The 22-year-old Frenchman had won four gold medals and was the poster boy of the Olympics this summer.
The Frenchman becomes the first male swimmer since American record-breaker Michael Phelps at Beijing 2008 to win four individual golds in a single Games.
American great Ledecky again set new standards, cementing her reputation as the greatest distance swimmer the sport has known.
The Frenchman will also go for gold later on Wednesday in the 200m breaststroke.
The men's and women's triathlons were given the green light a day after the men's event had been postponed because of pollution levels in the Paris waterway.
The 22-year-old was greeted with a massive roar when he entered the arena and the noise did not let up until long after he had touched the wall in an Olympic record time.
