Sweden's September 13, 2026, general election produced a narrow 176-173 seat majority for the center-left bloc led by Social Democrats under Magdalena Andersson, prompting incumbent Ulf Kristersson to resign and triggering standard Riksdag formation procedures. Andersson received the initial mandate but returned it after failing to secure unified support, particularly from the Left Party over speaker and coalition issues. This leaves ongoing speaker consultations and potential alternative mandates, including to Kristersson's Moderates, amid typical coalition arithmetic challenges in Sweden's multi-party system. Traders assign Andersson the highest implied probability due to her party's seat plurality and bloc leadership, while smaller shares for other figures reflect limited paths outside the main blocs. Scheduled committee formations and any further votes could influence the timeline.
