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

Platform comparison

Market context

Russia’s next State Duma election is scheduled for 18–20 September 2026, and the market will be decided by which party increases its seat total the most versus the last Duma, not simply which party finishes first. United Russia starts from an already dominant position after winning 324 seats in 2021, so the key question is whether it can still add seats in a chamber where its baseline is high and the opposition is fragmented.[4][10]

That framing is why the current 67% crowd view sits close to the polling picture: recent projections still put United Russia well ahead on seats, with FOM estimating 243 seats for United Russia versus 70 for KPRF, 69 for LDPR, 41 for New People and 27 for A Just Russia – For Truth.[1] Comparable recent projections from other polling models also keep United Russia comfortably in front, although some suggest only modest seat growth rather than a large jump, which matters because the market is about seat gain, not raw vote share.[3][6]

Traders should watch the final candidate registration, any changes to district boundaries or seat allocation, and whether opposition parties are allowed to run full nationwide lists, because those factors affect who can convert votes into seats.[10][11] The main dependency is whether United Russia’s single-member district dominance holds; if it does, the party remains the most likely candidate to post the largest seat gain, but a stronger-than-expected showing by New People or the LDPR would narrow that gap.[1][3][8]

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.
