In the Forbes 2025 ranking, which takes into account the assets of the whole family, Mordashov ranks first among Russian billionaires (US$30.5∅B). . When he was 37, Forbes ordained him (along with Oprah) as a "new arrival" in the world of billionaires.

Mordashov was mentioned in the Panama Papers and FinCEN files leaks – a company associated with Mordashov paid for a number of Vladimir Putin's pet projects and gave generously to close Putin associates.

He is under sanctions due to the Russian invasion of Ukraine.
