Which party will gain most seats in Russian Parliamentary Election?

Platform comparison

Market context

Legislative elections to the Russian State Duma are scheduled for 18–20 September 2026, with 450 seats at stake in the lower house of the Federal Assembly[1]. On Polymarket, the contract "Which party will gain most seats in Russian Parliamentary Election?" currently prices United Russia (ER) as the frontrunner at 56% probability, while New People (NL) trails at 33%[2]. This on-chain pricing reflects conditional tokens settled in USDC on the Polygon network, where traders are betting on the party that will secure the greatest net increase in seats compared to the pre-election baseline[2].

Historically, United Russia has dominated the Duma, holding 324 seats after the 2021 election with nearly 50% of the vote[1]. Comparable cases show that incumbent ruling parties in Russia typically maintain their majority, as confirmed by recent poll trends where governing parties hold 66.4% of seats[4]. However, New People is the only party currently showing potential for growth relative to 2021, though its standing varies significantly between polling agencies like VCIOM and FOM[5]. This volatility frames the 56% market probability as a cautious bet on continuity rather than a guaranteed outcome.

Traders should monitor official campaign announcements and the Kremlin’s preparation strategy for the first State Duma election since the war against Ukraine began[3]. Key catalysts include the release of final candidate lists and shifts in voting intention trends, particularly for New People, which holds second place in some polls but lags in others[4][5]. Recent analysis from the Nest Centre highlights how the Kremlin is structuring the electoral environment, which will directly influence seat allocation[3]. Any deviation in these scheduled dependencies could alter the conditional token settlement before the 30 September 2027 deadline.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
