Background
editRussian Kliment Kolesnikov, representing the Neutral Athletes B team, entered as the favourite with the world record of 23.55 seconds and the fastest qualifying time of 23.90. His compatriot Pavel Samusenko had the second fastest qualifying time of 24.01. Other contenders included Ksawery Masiuk of Poland, who earned bronze at the 2024 World Championships and held a 24.44 national record, and Pieter Coetze of South Africa, ranked 10th globally. European challengers included Hubert Kós of Hungary, Thomas Ceccon of Italy, and Apostolos Christou of Greece. The United States fielded Shaine Casas and Quintin McCarty, and Isaac Cooper of Australia and Xu Jiayu of China were also in contention for medals.[3][4]
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 25.11 seconds. 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 25.99 seconds. 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.[5][6]
