Magdalena Andersson leads trader pricing at 80.5% as leader of the Social Democrats, whose centre-left bloc secured a narrow 176-173 seat majority in the September 13, 2026, Riksdag election. This positions her bloc to form the next government under Sweden’s parliamentary rules, even as internal negotiations among the Social Democrats, Left Party, Greens, and Centre Party remain stalled over coalition terms. Ulf Kristersson sits at 15.5% reflecting his status as caretaker prime minister from the Tidö parties and recent Novus polling gains for the Moderates plus rising personal trust ratings. Ebba Busch and Jimmie Åkesson trail at 3.5% and 1.1% because the right-wing bloc lacks the seats for a majority without cross-bloc support that has not materialized. The speaker’s upcoming Thursday vote on Andersson, expected to fail, and subsequent rounds keep formation timing uncertain but still favor the election-winning bloc’s primary candidate.
