Recent opinion polls for Sweden’s September 13 parliamentary election show the Social Democrats leading, followed by the Sweden Democrats and Moderates, leaving a tight cluster of smaller parties—Left Party, Centre Party, Greens, and Christian Democrats—vying for fourth place with support levels between roughly 6% and 8%. Trader pricing reflects this uncertainty, with those four parties holding the highest implied probabilities while others trail. Limited recent differentiation in polling averages, combined with stable bloc dynamics and no decisive campaign events in the past month, has kept probabilities closely matched. Further shifts could arise from the final weeks of campaigning, televised debates, or movements near the 4% threshold that alter turnout or preference flows among centrist and left-leaning voters.
