Pronóstico: Which party will gain most seats in Russian Parliamentary Election?

Platform comparison

Market context

Legislative elections are scheduled to be held in Russia on 18–20 September 2026, with 450 seats in the State Duma of the 9th convocation at stake[1][3]. Going into this contest, United Russia remains the ruling party, having secured 324 seats and 49.8% of the vote in 2021[1]. Current on-chain pricing on Polymarket reflects a 55% probability that United Russia will gain the most seats compared to its pre-election tally, a figure anchored in USDC settlements on the Polygon network using conditional tokens.

Historically, Russian parliamentary elections have consistently favoured the incumbent party, with United Russia dominating the 2021 and 2016 cycles by maintaining or expanding its seat share[1][8]. Comparable cases show that opposition parties like New People, CPRF, and LDPR have struggled to achieve significant growth, though New People is the only party currently showing potential for gains relative to 2021 levels[4]. This historical pattern frames the current 55% probability as a conservative estimate rather than an aggressive bet, given the entrenched dominance of the ruling party in the authoritarian system[7].

Traders should monitor announcements from the newly appointed Central Election Commission regarding voting procedures and coalition scenarios, as these will shape the final seat distribution[3][6]. Recent polling from PolitPro indicates United Russia (YeR) leads with 46.4%, while VCIOM data places New People in second place at 13.4%, though FOM data suggests a different ranking where New People trails CPRF and LDPR[2][4]. The settlement window ends on 20 September 2026, with results needing definitive confirmation by 30 September 2027 to avoid an "Other" resolution, making the timing of official announcements a critical dependency for market settlement[1].
