On August 4, Gilman competed in the first date of the men's freestyle 57 kg of the 2020 Summer Olympics, where he went the distance in a razor-close loss to eventual winner of the Olympic Games and two-time and reigning World Champion Zaur Uguev from the Russian Olympic Committee. As the Russian kept advancing on the bracket, Gilman was pulled into repechage to compete on August 5, dominating Gulomjon Abdullaev from Uzbekistan and '19 Asian champion Reza Atri from Iran in order to capture the bronze medal for the United States.
