The centre-left bloc’s narrow 176-173 seat victory in Sweden’s September 13, 2026, parliamentary election established Magdalena Andersson’s Social Democrats as the largest party and positioned her to lead government formation talks. Kristersson’s resignation opened the process, but Andersson returned her exploratory mandate on September 28 after the Left Party withdrew support over the speaker election, leaving the Riksdag speaker to consult other leaders. This impasse has kept trader consensus on Andersson elevated while sustaining modest pricing for Kristersson, whose Moderates gained ground post-election, and smaller-party figures such as Ebba Busch and Elisabeth Thand Ringqvist. Ongoing negotiations and the four-candidate limit before any snap election remain the main variables affecting probabilities.
