In the semifinals the following day, Murphy swam the fastest in both semifinals heats with a time of 52.24 and advanced to the final.

His time of 52.19 seconds won him the bronze medal. Speaking to national newspaper USA Today about winning the bronze medal after winning the gold medal in 2016, Murphy said, "Winning an Olympic gold means you're the best in the world. Being third in the world is no slouch." On the fifth day of competition, Murphy advanced to the semifinals in the 200-meter backstroke with a time of 1:56.92, seventh overall in the prelims. In the semifinals, Murphy swam over one second faster than in the prelims with a time of 1:55.38 and qualified for the final in third place.

In the final of the 4×100-meter mixed medley relay, Murphy swam the backstroke leg of the relay, Lydia Jacoby the breaststroke, Torri Huske the butterfly, and Caeleb Dressel the freestyle leg of the relay; they placed fifth. It was the first time the event was included in the Olympic program for swimming. Murphy held off the field in his leg of the relay, tying Thomas Ceccon of Italy for first at the wall. The American team fell to eighth place by the end of the butterfly leg of the relay but made up some time on the freestyle leg to place fifth overall. Jacoby's goggles had fallen off during her leg of the relay, to which Murphy responded, "Anyone that's swam with their goggles in their mouth like she did, she did fantastic." On the final day, Murphy swam backstroke in the final of the 4×100-meter medley relay with teammates Michael Andrew (breaststroke), Caeleb Dressel (butterfly), and Zach Apple (freestyle). The relay won the gold medal in a world record time of 3:26.78, setting a new Olympic record in the process. By the end of the 2020 Olympics, Murphy had won a total of six Olympic medals, four in individual events and two in relay events, between his first (2016) and second (2020)
