Maxime Grousset of France led the 2024–25 season rankings, having improved his national record to 50.11 at the 2025 French Elite Championships. Canada’s Ilya Kharun and Josh Liendo ranked third and fourth in 2025 with 50.37 and 50.46, respectively; Liendo was the 2024 Olympic silver medalist and Canadian record holder with 49.99.

Qualification
editEach National Federation was permitted to enter a maximum of two qualified athletes in each individual event, but they could do so only if both of them had attained the "A" standard qualification time. For this event, the "A" standard qualification time was 51.77. Federations could enter one athlete into the event if they met the "B" standard qualification time. For this event, the "B" standard qualification time was 53.58. Athletes could also enter the event if they had met an "A" or "B" standard in a different event and their Federation had not entered anyone else. Additional considerations applied to Federations who had few swimmers enter through the standard qualification times. Federations in this category could at least enter two men and two women to the competition, all of whom could enter into up to two events.[4][5]
