Which party will gain most seats in Russian Parliamentary Election?

Platform comparison

Market context

Parliamentary elections are scheduled to take place in Russia on 18–20 September 2026, with 450 seats in the State Duma at stake. On Polymarket, this contract currently trades at a 2% implied probability for the "YES" outcome, reflecting the market’s view that no party other than the incumbent United Russia is likely to gain the most seats. The platform settles in USDC on the Polygon network using conditional tokens, meaning traders are betting on the on-chain resolution rather than the abstract political event.

Historically, Russian legislative elections have consistently reinforced United Russia’s dominance, as seen in 2021 when the party secured 324 seats with 49.8% of the vote. Current polls from PolitPro show United Russia (YeR) leading with 46% of voting intentions, while the incumbent coalition holds 66.2% of projected seats. Only New People shows potential for growth compared to 2021, but even VCIOM and FOM polls place it far behind United Russia, with conflicting figures on its actual standing.

Traders should monitor official announcements from the Kremlin regarding election preparations, as well as shifts in polling data amid Russia’s economic slowdown, which may fuel social discontent. The Russian Election Monitor recently highlighted that this will be the first State Duma election since the war against Ukraine began, adding a unique plebiscite dimension to the vote. Any unexpected changes in party list registrations or regional candidate endorsements could serve as catalysts, though United Russia’s entrenched position makes a breakthrough for another party highly improbable.
