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

Platform comparison

Market context

Legislative elections to the 9th State Duma are scheduled for 18–20 September 2026, with 450 seats contested across party lists and single-member constituencies, including 11 newly created in occupied Ukrainian territories. United Russia, the ruling party holding 312 seats, is expected to retain its constitutional majority, while the market assigns only a 2% chance to any party gaining the most seats compared to the pre-election baseline. This low probability reflects historical precedent: in 2021, United Russia lost 19 mandates overall but still secured a constitutional majority, and non-systemic opposition has consistently labelled such elections as falsified due to systematic exclusion of independent candidates.

Traders should monitor the finalisation of the new constituency map, introduced in April 2025, and the outcome of primaries concluded in May 2026, which placed at least 37 incumbent deputies in non-viable positions, particularly in Krasnodar Krai, Tatarstan, and Bashkortostan. The party list for United Russia is expected to be headed by Dmitry Medvedev, alongside Sergei Lavrov and war participants, signalling a deliberate effort to appease the radical pro-war segment of the electorate. Recent polling volatility for New People—holding second place at 13.4% in VCIOM but trailing at 6% in FOM—underscores the fragility of opposition momentum, while internal purges within New People and LDPR, including the detention of Sergei Natarov and the wanted status of Alexey Boykov, further weaken potential challengers. Any shift in the 2026 map boundaries or unexpected candidate withdrawals could alter the seat-gain calculus, but structural dominance by United Russia remains the defining feature.

Methodology

Football-specific comparison page for Pronóstico: Which party will gain most seats in Russian Parliamentary Election?. Polymarket's live quote (Polygon order book) plus platform attributes for the three reference venues. Sports markets reward liquidity — Polymarket and Betfair are materially deeper than Kalshi (US-focused) or Manifold (play-money).

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
