Artyom Zdunov, the United Russia incumbent heading the Republic of Mordovia since 2020, holds overwhelming trader consensus at 98.8% due to standard patterns in Russian regional head elections. He received presidential backing for nomination earlier in the year and benefits from established party machinery, administrative resources, and limited effective opposition in a multi-day vote running September 18–20. Registered challengers including Aleksandr Aleksandrov of the CPRF, Timur Geraskin of A Just Russia, Dmitry Masserov of the Greens, and Yevgeny Tyurin of the LDPR face structural barriers typical for non-ruling party candidates. The market assigns them minimal implied probability, consistent with historical outcomes where Kremlin-aligned incumbents secure decisive majorities. Late shifts remain possible only from unforeseen developments such as major health events or administrative disruptions before polls close.
