Ukraine would host one of the groups in the tournament under the plan which is understood to have been sanctioned by Ukraine's president Volodymyr Zelensky and the governments of Spain and Portugal, according to The Times.
The new partnership is reportedly to be announced by Spain and Portugal football chiefs during a news conference at European governing body UEFA's headquarters on Wednesday.
Ukraine has been under invasion from Russia since February 24 with the national team and domestic leagues taking place behind closed doors in Poland, who they co-hosted Euro 2012 alongside.
Reuters has contacted the sport's world governing body FIFA, which organises the World Cup, and UEFA for comment.
The 2022 World Cup will begin on November 20 in Qatar, while the 2026 edition will be played in the US, Canada and Mexico.
