Brazil's Alison Dos Santos added silver to the gold he gained in 2022. Samba returned to the world podium for the first time since Doha in 2019, when he also claimed bronze.
Benjamin managed to maintain his momentum, despite knocking down the final barrier, and dipped to victory in 46.52 secs to hold off dos Santos, who clocked 46.84 secs. Dos Santos and Samba both passed defending champion Karsten Warholm of Norway in the closing stages, as did Ezekiel Nathaniel, who clocked a Nigerian record of 47.11 to pip him into fifth place and move to 10th on the world all-time list.
