Hungarian Katinka Hosszú was a heavy favorite coming in to 2016. She had won both IMs at the 2013 and 2015 World Championships, and the 2012, 2014, and, earlier in the year, at the 2016 European Championships. But her form in 2016 had not been quite as strong, so there was some daylight for the other swimmers. Other medal challengers were considered to be Americans Maya DiRado and Elizabeth Beisel and Spain’s Mireia Belmonte.

Hosszú may have been sandbagging or simply training through competitions, as she returned to form in Rio, winning this event by almost five seconds over DiRado, in the world record time of 4:26.36, as Belmonte took bronze. Hosszú came to Rio having won 56 international medals, but never an Olympic medal. She would win three golds and four medals in Rio, also winning the 200 IM and the 100 backstroke. DiRado took bronze in the 200 IM but defeated Hosszú in the 200 backstroke to win that gold medal, adding another gold in the 4x200 free relay. Belmonte also added another individual gold, winning the 200 butterfly.
