### 2019–2021

At the 2019 World Aquatics Championships, Horton won silver in the 400 m freestyle event where he came runner up to Sun Yang. In a controversial "stand-off" Horton refused to shake the hand of Sun or to stand on the winners' podium. Horton had previously called Sun a "drug cheat". On 28 February 2020, Sun was issued an 8-year ban by the Court of Arbitration for Sport (CAS) for tampering with the doping control process, with calls to reissue medals from affected events, though the CAS clarified that Sun would not be stripped of any of his medals because "doping tests performed on [Sun] shortly before and after the aborted doping control in September 2018 were negative" and "in the absence of any evidence that [Sun] may have engaged in doping activity ... the results achieved by [Sun] in the period prior to the CAS award being issued should not be disqualified." Horton has been criticised for remaining silent on Australian swimmers who have faced punishments for violating anti-doping rules.
At the 2021 Australian Swimming Trials, Horton came third in the qualification final for the 400m freestyle, failing to qualify behind Elijah Winnington and Jack McLoughlin. Horton would also make it to the final for the 200m freestyle and would come sixth, earning him selection for the 2020 Olympics in the squad for the Men's 4 × 200 m freestyle relay.

## Personal life

On 16 September 2023, Horton married his high school sweetheart Ella Walter, a nurse. They had been dating since 2015 and got engaged in January 2022. In one of the interviews, Horton described Walter as "the secret to his swimming success".
In 2019, both Horton and Walter became subjects of online abuse and death threats from fans of Chinese swimmer Sun Yang after Horton staged a podium protest at the world swimming titles in South Korea and refused to shake hands with Sun pointing out that he was unhappy that Sun had been allowed to compete at the world titles ahead of a Court of Arbitration for Sport hearing to decide his fate in a long-running doping allegations scandal.
