For the third Olympics in a row Usain Bolt had won the 100 metres and 200 metres. In the previous two Olympics the Jamaican team with Bolt had won the gold in the relay. Jamaica with Bolt; his predecessor as world record holder Asafa Powell; and the equal second fastest man in history, Yohan Blake, were favourites. Powell had been on the 2008 winning team, Blake had been on the 2012 winning team. USA were expected to be the strongest opposition with the Olympic 100m silver medalist Gatlin; Tyson Gay tied for second fastest in history; and the World Indoor Champion Trayvon Bromell.

The Asian 4 × 100 m record was improved three times at the 2016 games. The record before the Olympics was 37.92, run by China at the 2015 World Championships in Beijing. In the first semi final, with a new lead off leg, China improved the record to 37.82. Japan improved the record twice, to 37.68 in the second semi final and a new record of 37.60 in the final.

In the heats, Jamaica, USA and Canada rested their stars, while Japan and China did not. USA had the fastest qualifying time winning heat 1 ahead of China, Japan the second best time winning heat 2. Jamaica squeaked through to second place in their heat giving those four teams the preferred center lanes on the track, while Canada's third place relegated them to an outer lane.

The final began with USA in lane 3 and Jamaica in lane 4, with the USA's Mike Rodgers vs Powell. In the first leg the leaders were Jamaica, USA and Japan with lead off runner Ryota Yamagata. At the first handoff, both USA and Jamaica ran up on their outgoing runners, Gatlin and Blake, to their outside, Japan's exchange went smoother, gaining more than a meter. At the second handoff, things went smoother for all the teams as Jamaica, USA and Japan looked about even, with Nickel Ashmeade, Gay and youth world record holder Yoshihide Kiryū for the three leaders. Through the turn Kiryū appeared to gain against both Jamaica and USA. China were next, with Canada, Great Britain and Trinidad and Tobago further back. After the final baton change, the world junior record holder, Bromell, against world record holder Bolt, and Asuka Cambridge, a half-Jamaican Japanese runner, Bolt seemed to gain an edge on both Japan and USA, but had to slow as he fumbled to grab the baton. Leaving the zone Bolt only had inches on the other two leaders. Down the straightaway, Bolt pulled away to lead by two metres and Cambridge held a smaller lead over Bromell which Bromell could not close. Jamaica had a clear win, with Japan clearly second and USA third with Bromell falling at the finish line. The Andre De Grasse-anchored Canadian team finished fourth which became significant. Almost fifteen minutes after the race, after USA had joined Jamaica and Japan in their victory lap, the USA team were disqualified for exchanging outside the designated zone in the first baton change. Replays showed the baton change began before Rodgers and Gatlin had entered the exchange zone. Gatlin's late start resulted in Rodgers reaching Gatlin too early. The disqualification meant that Canada was elevated to the bronze medal, which was in stark contrast to four years ago when the Canadians, believing they had successfully secured the bronze medal when the race ended, were disqualified for a lane infringement.

Jamaica won the gold for a third consecutive time, and Usain Bolt won his 9th track and field gold medal. This also gave him the distinction of being the first man in history to complete the Triple-Triple (winning the 100 metres, 200 metres and 4 × 100 metres relay, in 3 successive Olympics). His accomplishment was later mooted by the doping disqualification of his teammate in 2008, Nesta Carter, reported in January 2017.

The following evening, the medals were presented by Valeriy Borzov, IOC member, Ukraine, and Du Zhaocai, Council Member of the IAAF.
