Market context

Legislative elections for Russia’s State Duma are scheduled to take place from 18 to 20 September 2026, with 450 seats contested in the lower house of the Federal Assembly. On Polymarket, the contract “Which party will gain most seats in Russian Parliamentary Election?” currently prices United Russia (ER) as the frontrunner at 61%, while New People (NL) holds second place at 30%[2]. The market assigns only a 2% probability to the “YES” outcome for any party other than United Russia gaining the most seats, reflecting strong on-chain confidence in the ruling party’s dominance despite the election being the first State Duma vote since the war against Ukraine began[3].

Historically, United Russia has maintained overwhelming control, securing 324 seats and 49.8% of the vote in the 2021 election, a pattern that frames today’s low probability for challengers[1]. Comparable cases show that while New People is the only party demonstrating potential growth compared to 2021, polling remains volatile: VCIOM places them at 13.4%, whereas FOM estimates just 6%, trailing both CPRF and LDPR[4]. This divergence underscores why the market heavily favours United Russia, as no opposition party has consistently outperformed the ruling party in recent cycles.

Traders should monitor Kremlin preparations for constituency boundary changes, which authorities are already adjusting ahead of the 2026 vote[8]. Key catalysts include official campaign announcements from New People, LDPR, and Just Russia, as well as the release of updated polling data from VCIOM and FOM[4]. The election schedule is fixed for September 2026, but definitive results may not be known until late September 2027, creating a long settlement window that ends on 20 September 2026 for the market’s primary resolution date[1][9]. Conditional tokens on Polygon, settled in USDC, will execute automatically once results are confirmed, ensuring transparent on-chain settlement without intermediary discretion.

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
