Polymarket Contradiction: Odds Favor United Russia to 'Gain Most Seats' Despite Projections of Significant Losses in Upcoming Duma Election

A Polymarket prediction market on the Russian parliamentary election shows high confidence in United Russia gaining the most seats, even as recent polls and analysis suggest the ruling party is set to lose a substantial number of mandates.

The upcoming Russian parliamentary elections, scheduled for September 18-20, 2026, are drawing significant attention, including on prediction markets like Polymarket. A specific market asks: "Will United Russia (ER) gain the most seats in the next Russian parliamentary election?" With a trading volume of over $8.8 million, the market currently shows a 69.5% probability for "Yes" (United Russia gains the most seats) against a 30.5% probability for "No". However, a closer look at recent data and analysis reveals a potential mispricing, as projections indicate United Russia is more likely to lose, rather than gain, seats.

The Market and Its Stakes

This Polymarket focuses on which political party will achieve the greatest increase in its seat count in the State Duma, compared to its performance in the 2021 election. The 2026 elections will fill 450 seats in the State Duma, with 225 elected by party-list proportional representation and 225 in single-mandate constituencies. For the Kremlin, these elections are not expected to bring significant political change but rather serve as a "managed procedure" to renew institutions and complete the current political system's transformation.

United Russia's Shifting Landscape

United Russia (ER), the ruling party, secured a constitutional majority in the 2021 elections with 324 seats (49.8% of the vote). However, the political landscape has evolved significantly, particularly with the ongoing conflict in Ukraine. Recent polls suggest declining support for United Russia. While state pollster VTsIOM reported United Russia's support at 35.3% in mid-July 2026 (down from 49.82% in 2021), the PolitPro Election Trend, which aggregates data from various institutes, shows United Russia with 47% support as of August 30, 2026.

Crucially, the Kremlin's internal expectations for United Russia's vote share have reportedly been lowered from an initial 55-60% to an average of 45-50% nationwide, with sources close to the Presidential Administration not ruling out further drops. This decline is attributed to public fatigue with the war, economic anxieties, and disruptions caused by Ukrainian strikes on Russian territory.

Projections vs. Polymarket Odds

Based on the PolitPro Election Trend's projected seat distribution for the 2026 elections, a stark contrast emerges when evaluating the "gains the most seats" criteria:

  • United Russia (ER): Projected 234 seats in 2026. Compared to 324 seats in 2021, this represents a loss of 90 seats.
  • New People (NL): Projected 55 seats in 2026. Compared to 13 seats in 2021, this is a gain of 42 seats.
  • Liberal Democratic Party of Russia (LDPR): Projected 63 seats in 2026. Compared to 22 seats in 2021, this is a gain of 41 seats.
  • Communist Party of the Russian Federation (CPRF): Projected 71 seats in 2026. Compared to 57 seats in 2021, this is a gain of 14 seats.
  • A Just Russia – For Truth (SRPZP): Projected 27 seats in 2026. This is no change from their 27 seats in 2021.

These projections suggest that United Russia is on track to lose a significant number of seats, making it highly improbable for them to "gain the most seats." Instead, parties like New People and the LDPR are projected to see substantial increases in their mandates. The Yabloko party, an anti-war opposition force, has also faced pressure, with Russia's Supreme Court removing it from the ballot in August 2026.

Analysis of Market Discrepancy

The current Polymarket odds, heavily favoring United Russia to gain the most seats, appear to contradict the available polling data and seat projections. This discrepancy could stem from several factors:

  1. Misinterpretation of Market Rules: Participants might be overlooking the specific resolution criteria of "gains the greatest number of seats" rather than simply retaining the most seats overall.
  2. Skepticism of Polls: Market participants may distrust public polling in Russia, given the history of electoral management and the current atmosphere of repression.
  3. Anticipation of Electoral Manipulation: There might be an expectation that the Kremlin will ensure United Russia is officially reported as gaining seats, regardless of actual voter sentiment or pre-election projections.

While United Russia is still expected to retain its overall majority in the Duma, the market's focus on gains presents a different challenge. The significant volume on this market suggests strong conviction, but the underlying data points to a potential disconnect between market sentiment and projected outcomes for the ruling party's seat changes.
