United Russia secured a projected record 355 seats in the 450-seat State Duma following the September 18–20, 2026, legislative elections, driven by 57.8 percent support in the party-list vote and leads in 208 of 225 single-member districts. This outcome reflects the party's entrenched dominance in a tightly managed process that excluded significant opposition, combined with elevated turnout near 59 percent and official framing of the vote as a demonstration of national unity. The results maintain the party's constitutional majority well above the 301-seat threshold, consistent with historical patterns of incumbency advantage under the mixed electoral system. Final seat allocation remains subject to complete counting and any redistribution among qualifying parties that cleared the 5 percent threshold. Scenarios that could alter the tally include adjustments from remaining precincts, legal challenges to specific district results, or procedural reallocations, though preliminary data from the Central Election Commission strongly support the current projection.
