Notes

edit
  1. ^ Ilya Kharun initially represented Canada before announcing in January 2026 his intention to switch sporting citizenship to the US. Under World Aquatics rules, athletes must cease representing their former nation for 12 months before they can represent their new nation; Kharun becomes eligible to represent the US in October 2026. The attributed nation (or lack thereof) indicates which team he represented at the time.
