In June 2021, while announcing the FIDE Grand Prix 2022, FIDE gave its preferred match date as "at the end of 2022 or beginning of 2023". On 8 December 2021, FIDE President Arkady Dvorkovich announced that the Candidates was planned to be held in the (northern) of summer 2022 with the World Championship to follow in early 2023.
Radjabov had qualified for the previous Candidates Tournament, but withdrew after his request to postpone the tournament due to the COVID-19 pandemic was refused. With the postponement of the 2020 Candidates Tournament at the halfway point due to the pandemic until its resumption in 2021, Radjabov called for his reinstatement into the tournament. FIDE decided that it was appropriate to instead give Radjabov a direct entry into the 2022 Candidates.
