Trader consensus on Polymarket heavily favors the Swedish Social Democratic Party (S) to secure the most seats in Sweden's September 13, 2026, Riksdag election, reflecting its sustained double-digit lead in recent polls at 32-33%—well ahead of Sweden Democrats (SD) at around 20% and Moderates (M) at 17-18%, per Kantar-Sifo (April 11), Verian (April 5), and Indikator (April 1). This positioning stems from the incumbent right-wing Tidö bloc's erosion, highlighted by Liberal Party turmoil after its March 13 "Sweden Promise" pact with SD triggered resignations and a narrow leadership survival for Simona Mohamsson on March 22, fragmenting potential coalitions. Seat projections grant S ~120 mandates versus SD's 75 and M's 64, though centre-left (S+V+C+MP) and right blocs hover near parity; economic pressures and immigration debates sustain S momentum amid stable polling trends over the past 30 days. Late scandals or shifts could narrow the gap before election day.
