Sidakov has supported the Russian invasion of Ukraine by participating in a pro-war rally in Luzhniki Stadium in March 2022.

Despite being children at the time, they understood what was happening when being evacuated from school, said Sidakov and he had friends and training partners who were being held as hostages.

In 2016 he captured his first gold medal at the Grand Prix by defeating Russian National champion, Khusein Suyunchev.

In the quarter-final, he beat NCAA champion, Olympic gold medalist and four-time world champion Jordan Burroughs 6–5, and Sidakov then beat Olympic Bronze medalist, and two-time European and World champion, Frank Chamizo by 3–2, advancing Sidakov to the final, opposite Georgia's Avtandil Kentchadze, a 2018 U23 European Championships Bronze Medalist – whom Sidakov defeated at the U23 Senior European Championships in the semi-final.

[citation needed] Sidakov was then placed on the Russian squad to wrestle at the 2019 European Games held in the capital of Belarus, Minsk.

[citation needed] At the 2019 World Championships, Sidakov first defeated Mexican representative, Victor Hernandez, by a technical fall, 10–0.

Sidakov would start his run with a fall win over Khanty-Mansiysk's Tsyrenov, followed by a 4–0 shut-out against Dagestan representative Dzhaparov.

In the final match, Sidakov faced Dagestan representative Razambek Zhamalov, who trains under the Saitiev brothers, in Khasavyurt.

On August 5, in the round of 8, Sidakov was matched up with former Olympian, Augusto Midana of Guinea-Bissau, who was defeated by a 12–2 tech-fall, resulting in a successful Olympic debut.

Sidakov would fairly easily dispatch of Kaisanov by a 11–0 tech-fall,[29] resulting in an advancement into the 74 kg finals opposite former Russian, and now Belarusian representative, Magomedkhabib Kadimagomedov.

[30] In the final against Kadimagomedov, Sidakov controlled ties and always had strong wrist control, which rendered Kadimagomedov's strong over-hook offense ineffective and never afforded his opponent to get in a good shooting position; Sidakov would win by 7–0,[31] accumulating one passivity point, a takedown, a cradle attempt and two push-outs to win the gold medal.

[34] Sidakov returned at the Dmitry Korkin Memorial where he defeated Kurban Shiraev in the final, winning the gold medal.

[35] Sidakov started the wrestling season with a gold medal at the Ivan Yarygin Golden Grand Prix after defeating Timur Bizhoev 4-0 in the final.

[36][37] Sidakov planned to wrestle at the Russian National Championships, held in Kaspiysk, Dagestan, but had to withdraw due to illness.

[40] In a tightly contested match, Sidakov defeated his teammate by the score 3-2,[41] winning a ticket to the 2023 World Wrestling Championships.
